Sure it is. The point is Peak GL is an unique product that is patented by Peak. However, it CANNOT be compatible if it doesn't contain phosphates from Asian vehicles and it cannot be compatible with other vehicles that require silicates.

Where do I begin? Yes Deathcool replaced the green stuff GM used. It was a totally reformulated product that GM hoped would last longer than the green stuff. And since they have a lot of pensions to pay, it is helpful having a name they can license for other companies to make Deathcool. Of course history has shown us a lot of people have had problems with Deathcool and have actually replaced it with the green stuff. A class-action lawsuit against a coolant technology says it all. I am pretty sure green, Asian, and G-05 have never been sued.

G-05 is very similar to Green and because of the OAT it has a longer service life than Green. But keep in mind we are not talking about filling classic cars that maybe ahve iron blocks, brass radiators etc, that originally were factory filled with Green. Those cars should get Green anyway, and perhaps you're right G-05 is the next most compatible choice. We were discussing cars that did not come with green originally. Also what you are saying only supports my staements earlier that Green worked fine in Asian cars.

Baloney? So a company that says there should be multiple coolants available is wrong? That's nuts. At least Zerex and Havoline offer G-05, Deathcool, and green. Zerex takes it a step further with their Asian and Extended Life formulations. In a nutshell, Zerex has 5 possibilities to choose from and Havoline has 3.

On the rest of your quote, very good! But somehow you have this idea that I am trying to get to OP to switch the G-05 when I am not. I am STRONGLY advising the OP to use Asian HOAT coolant for his Asian vehicle. And you are wrong about the classics. G-05 is superb in them...

"Turcotte says G-05 is less radical than Extended Life, and it's backward and forward compatible, which means that it can be mixed with green conventional antifreeze or the latest inorganic types. It's particularly well-suited to keeper cars, he thinks, because of the way it combats the sort of corrosion that comes with being a garage potato."

Turcotte is smarter than probably anyone on this board in regards to coolant.

How many times do I have to say that?

I am wondering if you have Deathcool stock or something. I stand by that bold statement. Prove me wrong if you can which you cannot. So you want the OP to use Deathcool? Are you crazy? How many times do I have to tell YOU that if OEM requires a phosphate HOAT or a silicate HOAT that it is best to stick to that formulation? Deathcool doesn't meet this requirement nor do any of the Deathclones nor does Peak GL.

TO THE ORIGINAL POSTER:
It's really your decision on what you want to use. You should really stick with the OEM recommended fluid which is Asian phosphate HOAT coolant.

PGL, G-05 or what have CAN be compatible in any car it's just not the same as the manufacture recommended/required formula. Anyone knows that. Just because a manufacture recommends something doesn't mean nothing else can work or can't be better. How many times have you said "deathcool" is crummy, yet it is factory recommended. I think you are too hung up on silicants and phosphates. But of course using the recommended fluid is the safest bet.

Well I think you are a little too suspicious of GM licensing. They are not going to get rich off a license. How is that any worse than some manufactures not licensing their required fluid and requiring you to get through them? Anyway,people have put Green with silicant in dexcool cars, just like people have used Green in European cars in the past. So as it goes, sometimes you go against the factory recommendation and the sky doesn't fall. you could add PGL to list of not being sued nor being known to cause problems.

I only said that one of Zerex's charts was baloney for recommending a dexclone for just about everything, but now that I think about it it might have been Prestone and if so I take that back. I don't think oiffering multiple coolants is wrong. What I do think is wrong is how manufactures can't get together and agree on a coolant.

I believe I said G-05 would be better in a classic, so this isn't the first time you've put words in my mouth so to speak. I don't disagree with anyone recommending the OEM coolant, but you still seem to have a strong favoritism of G-05 and dismissed PGL falsely earlier calling it a dexclone etc, but whatever. My point was we were never talking about classic that originally used Green when discussing coolant choice.

Well thanks for the link, it's good to hear that G-05 is compatible with classics and green but no mention of other organic types according to a Zerex guy. That really wasn't what's at debate here though.

I never recommend dexcool or a dexclone in anything but a GM vehicle. I don't have any real disagreement with someone suggesting to stick with the OEM coolant. But you seem to be implying that since G-05 is a H-OAT with silicates that makes it in fact better than any OAT period, or perhaps it could be more suitably used in an Asian car. You may only be recommending Asian formula for them. But you seem to dismiss PGL because it doesn't have silicants or phosphates, and while that does preclude it from being the recommended formula for an H-OAT application, that doesn't mean it can't or won't work as good or better in them.
 
Each of your replies above seem to contradict each other.

I also find it funny you have not linked to any evidence backing up our assertions whereas I have both here and in other threads we have participated in.
 
Actually Zerex has since modified their chart, removing the newer Dexcool for the Asian vehicles & replacing it with Asian Vehicle. IMHO, the reason the Japanese & Koreans recommend phosphate inhibitors is to protect against water pump seal failure due to silicate drop-out, GO-5 has actually been around longer than Dexcool (Mercedes), and is an EXCELLENT choice for older vehicles that came with green originally. Dexcool is great until you have problems-then it eats engines, case closed, sorry, GM stockholders! I'll add that Ford is now moving in the Asian direction as well-beginning to use Mazda FL-22 coolant in the Mazda-designed engines. A TEN YEAR lifespan for the factory fill of Toyota SLLC can't be a BAD sign!

And, I would agree with you. Zerex marketing aside, the only Asian make that I have seen specifically recommend phosphate in their coolant is Toyota.

I also find it now interesting, the new spin being put forth that anything other than OEM or a Zerex product(other than Zerex Dex) now being termed 'deathcool'. lol Peak Global Lifetime contains no 2eha, and therefore is not dexcool or a dexclone. Like Bill in Utah, I'd have no reservations/issues using it in any Asian vehicle including Toyota, whose branded coolant is too expensive, IMO.

Curiously though, Zerex still recommends Dexcool for many vehicles on the their coolant application chart. Also very curious is the fact, that before the introduction of their Asian coolant, Zerex recommended Dexcool for all Asian models. The pdf here still shows it.

I personally have now run Peak LL and Prestone AM in 2 different Asian makes, Nissan and Toyota, for ~5years with regular maintenance(2-3yrs/30-40k) with zero issues, both still have all original cooling system equipment. I've not been scared off by the dexcool/2eha monster (ie. some intake gaskets on some GM products). There's many cars, including GM, using dex that have had zero issues, with regular cooling system maintenance. That said, I can understand those that have their reservations about the dexclone universals, in such a case, Peak GL is a fine choice.

Lastly, before I would choose Zerex Asian Premix 50/50 for a simple radiator drain and refill of existing coolant chemistry, I would try to match the coolant chemistry already in the system. Failing that, I would do a complete distilled flush series choosing a new full strength coolant of choice, like Peak GL. Assuming I could find it, I would not mix Zerex Asian premix with existing chemistry. Until they make it in full strength, Zerex Asian won't be a considered choice for me.

I DO agree that 100% coolant.....and add my own distilled water would likely be cheaper....
But to the point of keeping the cooling system with fresh, clean coolant....doing a couple of drain and flushes....say...every 2 years should keep the system clean....and not needing any system flushing.


Asian vehicles for the most part specify NO SILICATES. G-05 is great antifreeze but it is low silicates rather than NO SILICATES as required.

Since we are picking apart each others arguments here (debating), I wish to add my comments about the use of dated links from so called "experts". Most of these "experts" are just stating their OPINION, which may, or may not be any better than the rest....watch: WHICH OPINION IS TO BELIEVED MORE, AND WHY?

Dr. Turcott (2002)
- suggested that the Zerex Extended Life would become a proven product for vintage vehicle....his OPINION didn't materialize.

- Turcott recommends G05 for vintage cars (vs Weissler below)

_ Turcott said you CAN intermix green and G-05, but is that best practice?

Ford says you CAN mix it also, but they RECOMMEND not doing it in this Ford FAQ:
http://www.paulmachenry.com/documents/CoolantFAQs.pdf
" What is the interchangeability of Motorcraft Premium Engine Coolant(Green) and Motorcraft Premium Gold Engine Coolant? Can Motorcraft Premium Engine Coolant be used to top off a vehicle equipped with Motorcraft Premium Gold Engine Coolant?
Ford does not recommend mixing coolants."

- Turcott states about G05 "I've got a 20-year history that says this really works." Then states at the end "I have no personal experience with any of these products."

Weissler:

Now we go to Weissler's link that you posted in another thread, regarding best coolant for vintage cars:"We have in previous articles pointed out that today's coolant inhibitor packages contain a small amount of copper-brass protection, but may provide little protection if a radiator is made with high-lead solder. Results of industry standard tests of the new Toyota extended-life coolant now show a substantial weight loss (corrosion), both in a 50-50 mix aud in a 33% coolant mixture (solder corrosion is much greater in this more diluted solution). If you have to change a radiator or heater core, use aluminum. Or, if it's an older car and the owner wants the lowest-cost radiator, you might procure a soldered-together copper-brass unit. Conventional American coolant should provide better protection against solder corrosion, which can result in radiator tube restrictions and leaks."

My point is, which of the linked "experts" are we to believe, Turcott, Weisler, or Ford? I tend to believe the manufacturer first, and use the others for learning purposes only. THEY POST OPINIONS, NOT THE GOSPEL

I can only agree with you and your experiences. If Dexcool is workable in Asian vehicles, I don't see any reason why PGL wouldn't be as or more workable. Zerex has been all over the map on their recommendations just as I recalled. It still looks like G-05 may lack compatibility as I suspected since Dexcool has been recommend more in Asian cars than G-05 has. All reasons why I've been suggesting a complete flush especially before switching to G-05. Then when Zerex comes out with an Asian Formula they change their recommendations lol.

Well Peak comes out with an AF that claims longer life and more capability than all of the others, and some people want to throw it under the bus just because it's not an H-OAT. They don't want to consider that PGL's OAT might be better than the rest and it might be an as good or better product.
 
Good points. "Experts" and even manufacturers don't agree and aren't really giving us any definitive data. The article was dated and Dr. Turcott was Zerek's guy just talking offhand and not giving out any real propietary or test data. Basically, all the article was about was replacing Green in classics with whatever Zerek would recommend. That's not really what the discussion here is about, ie, modern cars that used some type of H-OAT or OAT.

Some may take the simpler route and just go with whatever the OEM recommends. But what if you don't want to go with the OEM, say in a GM car with Dexcool? I'm of the view of favoring PGL over G-05.
 
I believe they are all good coolants and the most important thing is proper vehicle maintenance period. G-05 has been used in asian vehicles as well as Dexcool without any disastrous affects. My biggest problem is having three different coolant types Hoats Poats and PGL. PGL is getting hard to find,Not crazy about a Hoat in my Asian vehicles, Poats not available as concentrates, but when they are that is what I will probably use for all three.
 
What antifreeze patents does Old World Industries (the company that produces and markets Peak antifreeze products) hold? I just did a patent search and cannot find a single patent with Old World Industries as assignee.

In contrast, CCI, the inventor of Japanese first and second generation P-OAT technology, holds dozens of antifreeze patents. BASF, Prestone, and Texaco (now Chevron) also hold significant antifreeze patents.

Old World Industries is effective at marketing antifreeze but I have not been able to find any technical substance behind the company. Do they have a research laboratory? I can't find any technical publications written by Old World Industries scientists and engineers. What am I missing?

I agree with your assessments. You know, even places that carry it don't have much stock of PGL. That may be a sign that the aftermarket is really embracing PGL. We will see how it stands up to the test of time. You know what the ironic thing about Asian P-OAT is? I think if it didn't contain phosphates that don't work well if hard water is used, they'd probably be a lot more willing to offer it in full strength. I'm not saying they are justified or right though because Green has phosphates and is available in FS. Since it is not offered in full-strength and some cars are basically impossible to drain the block after a flush, what are you left with but G-05 or PGL (barring Dexcool of course)?

Coolant_Man, let me see if I have your advice straight. You recommend OEM coolant except if it's Dexcool. You don't recommend Dexcool or Peak GL either in anything because neither is a hybrid with silicant or phosphate (I think you are oversimplfying things and assuming but I've already went over that). So what if you have a GM vehicle? You've also said that traditional Green is damaging to new cooling systems. So what is left but Asian formula and G-05. GM block drains are either impossible or too much trouble getting to, and since Asian is a pre-mix it is ruled out. So that really only leaves G-05 for GM.

Personally, I'm not too crazy about silicates. And the easiest and most effective way to flush out many cars' cooling system is with a water hose connected to tap water and to a T-flush. Even though hard water is not an issue around here, I'd rather not use it with a phosphated anti-freeze even if the Asian was full-strength. Plus the potential for one coolant and not need 2 different ones or more and the potential to mix PGL with others in a pinch, are some of the reasons why I'm leaning towards Peak GL.
This is some of the reasons why I'm leaning towards PGL over G-05,
 
I really don't know. Maybe Old World Industries is owned by another parent company? With a name like "Old World", it makes you think it might be European. Maybe Old World Industries did not feel it was necessary to patent their inhibitor but only to not divulge what it is? I'd assume Old world has some patents somewhere. I never really tried to search for them I don't really know what can be concluded from your questions if anything. No other brand seems to have their OAT and non-Dexcool formula.

True that, the full strength was not available at Walgreens, and only a small amount of premix. A recent email from a fellow Bitoger regarding Peak Professional Lifetime available at Pep Boys, was answered saying that it is the same as PGL. It sounds like the similarity of Peak Extended Life available at Wally and Peak Long Life.

Quote:

Agree 100%. If you maintain the cooling system on a reasonable interval, then your cooling system will generally serve you well.
 
Oh this is going to be fun...

I think the best way to approach all of this is to link directly to a few Asian OEMs and their recommendations.

Now remember as you read these that the Asians want phosphates and not silicates whereas the rest of the world wants silicates so here we go...

Toyota
"Toyota recommends Genuine Toyota Long Life Antifreeze Coolant (factory red fluid) as the first choice when maintaining your vehicle. Toyota coolant was developed to meet the specific requirements of our engines and provides maximum protection without the use of harmful silicates. Silicates, a main ingredient in the vast majority of antifreeze coolants, can actually damage the water pump seal, causing leakage. Our coolant is a high-performance, non-silicate coolant that provides better protection for metals without deterioration of the water pump seal."

In other words, phosphates are used and Toyota water pumps are not compatible with silicates.

Mazda
"In extreme climate, at extreme temperatures, Genuine Mazda Super Coolant - specially formulated for Mazda engines - provides year-round protection. The Genuine Mazda Long Life Coolant (FL22) is a superior, high-quality coolant. It reduces the operating temperature of the engine and has anti-freeze protection to -44°C."

FL22 also contains phosphates.

Nissan
Page 8-9 "When adding or replacing coolant, be sure to use only a Genuine NISSAN Long Life Antifreeze/Coolant (green) or equivalent with the proper mixture ratio of 50% antifreeze and 50% demineralized or distilled water. The use of other types of coolant solutions or coolant colors, such as orange, may damage the engine cooling system."

The interesting thing about this is the warning to not use, "other types of coolant solutions or coolant colors, such as orange, may damage the engine cooling system." I would bet ORANGE means Deathcool. So we can also safely assume this covers Deathclones.

Now all of these Asian coolants are HOAT coolants. Instead of using a low dose of silicates, they use a low dose of phosphates.

Now the primary coolant manufacture for Asian coolants is CCI. It's US subsidiary is called Intac. Apparently, there is no website for Intac. This was the best I could find...

http://www.jei.org/Restricted/BR98/347x/347_JinUS_Chem.html

Now I am going to return to the point I have been trying to make not only in this thread but in others...

STICK WITH OEM!!!

Would it be nice to have ONE universal coolant? Sure! But the way things are today, that is not going to happen.

And I keep seeing this argument being brought up about Asian HOAT being pre-mixed. So what? They want you to flush with pre-mixed coolant only. Why? Because they know many owners of their vehicles will not use distilled water. Using the RIGHT coolant and the WRONG water can be disastrous to a cooling system. Use distilled water. I suppose one could flush out an Asian cooling system quite a few times with distilled water and then drain the entire cooling system and then flush a couple more times with pre-mixed coolant only. It would be nice though to have a concentrate to jack up the coolant ratio to 55-60%. I think it is the Nissan pre-mixed coolant that comes in 55% coolant to 45% distilled water so at least there is one out there going higher than 50/50.

Now mechanicx and sayjec believe you don't need a HOAT coolant using phosphates even though they are called for SPECIFICALLY by Asian OEMs. By their logic, you can use Deathcool in a Ford or a Chrysler though we know both of those companies investigated going to Deathcool and discovered it was bad so they therefore went to G-05. Those recommendations and warnings I linked to above are there for a reason.

In regards to Zerex recommending Deathcool for Asian vehicles prior to the introduction of Zerex Asian, it was not only them doing this. Havoline did the same thing and Super Tech, Prestone, and Peak are obviously still doing the same thing with their "universal" coolants. At least Zerex now as a formulation specifically for Asian vehicles. I think the fact Deathcool was recommended as an equivalent for Asian coolant was flawed.

Back to Peak GL. Peak says it works in everything. I don't buy this for one second. Peak GL DOES NOT CONTAIN silicates and it DOES NOT CONTAIN phosphates. So then someone please explain to me how it can magically work in Ford and Chrysler vehicles wanting silicate HOAT G-05 and how it can work in Asian vehicles wanting phosphate HOAT Asian coolant?

The fact remains that Peak GL is an OAT coolant. Deathcool and Deathclones are also OAT all of which contain about 90-95% Ethylene Glycol and about 5% Diethylene Glycol. Deathcool and Deathclones use 2-EHA and sebacate (both are plasticizers and organic). Peak GL uses something else. The Peak GL MSDS says this proprietary concoction is made of hydrated inorganic acid and organic acid salts. It is rare for an MSDS to list everything on it which I have never liked.

Even mechanicx has agreed it is best to stick with OEM but yet he still recommends a coolant that obviously cannot be OEM. That makes no sense to me.

I really don't know what more can be said on this subject. I stand be my signature 100% which currently says...

"There is no such thing as an All Makes All Models/Universal coolant. Stick with OEM unless it is Deathcool in which case switch to G-05/Zerex Green."
 
On your Turcotte section...

I guess we can assume something changed. That's the trouble with predictions. Perhaps there are classic car owners out there that do in fact use a diesel coolant such as Zerex Extended Life.

Turcotte did not say that at the end. That was the author of the article; Patrick Bedard.

On your Ford quote. This really is not a quote. I bet the author of that PDF is using information from the Motorcraft Online Catalog which lists each of its coolants and advices to not mix them with each other. I believe this is done simply to convey that the mixing of different coolants is not recommended. However, it is not impossible. I have plenty of G-05 to top off my vehicles as needed. If it were an emergency and I had no G-05, I would use distilled water until I could obtain some G-05. In more regards to G-05, if it is topped off with regular old green 3 yr./36K mile coolant, the long life properties of G-05 diminish.

Now on to your Weissler quote. He is correct. After all, this was the OEM coolant of that day. But conventional green is becoming harder to find. On top of that it is limited by it product lifetime. However, you did not use the full quote from the article which is this...

"If you have to change a radiator or heater core, use aluminum. Or, if it’s an older car and the owner wants the lowest-cost radiator, you might procure a soldered-together copper-brass unit. Conventional American coolant should provide better protection against solder corrosion, which can result in radiator tube restrictions and leaks. But no coolant provides perfect protection."

So who do believe? I agree with you to believe the OEM. The problem is we ahve to move on when the OEM recommendation is no longer available.

Yup that is pretty much it and it is quite simple. I am still waiting for you to provide valid links to back up your facts such as I have to back up my facts.

I certainly have not ruled out Asian HOAT. I have no problem with it being a pre-mix and have explained a few times why it is that way. There is NO WAY I would want to use traditional high silicate high phosphate American green coolant in any vehicle I own or work on. It is inferior to what is available now. I, my family, and my friends all drive original American vehicles. The best choice for them has been G-05 which I have been using since about 2003. If any of them were Asian, I would use Asian phosphate HOAT coolant without any reservation.

After all, there is no documented evidence of HOAT coolants turning into mud or eating gaskets like Deathcool as been documented as doing numerous times.

This is some of the reasons why I'm leaning towards PGL over G-05,

And this is the reason I use G-05. It works perfectly in all the vehicles I own and work on. Some silicates (and in regards to Asian coolants, some phosphates) are a good thing. They provide instant protection to cooling system surfaces that Deathcool, Deathclones, and Peak GL cannot do.

I'm not sure what facts I need to back up with links. There's no link necessary to back up the fact that Dexcool does not need inorganics to protect well. The field service has shown that. Your links are not backing up your statements.You make statements like the Asian want phospates and everyone else wants silicates, but that's not exactly the case. GM apparently didn't want silicants (or phosphates). And at the time dex-cool was introduced. there wasn't a real choice besides G-05. Diamler Benz probably had something to do with G-05 being selected by Chrysler, and Ford seems to be moving toward the Asian which does have phosphates. But the point is it looks like few really want silicants. Then you make the unfounded and leaping assumption that if you don't have one or the other inorganic, you'll have the problems of Dexcool (which you blow out of porportion). Sure Dexcool hasn't been enbraced, but you are making an assumptions about why it hasn't because it lacks an inorganic. You have no facts to prove that non 2-EHA OAT need an inorganic to prevent problems. What you have are assumptions.

Well you are entitled to your preference so I won't quible with that.

But there is no documented evidence that a non-hybrid OAT that doesn't contain 2-EHA such as PGL has ever sludged or ate gaskets either. I wish I could find the link but a Dupont study regarding coolants and plastic did show Dexcool was a little more aggressive to certain plastic than G-05, but G-05 wasn't harmles to them either. I can't remember the details, but the point is G-05 may not be much better. Also Dexcool doesn't just contain 2-EHA it contains sodium neodeconate (sp?) in licensed Dexcool that states it's ingredients. So Dexcool may have been revised slightly from it's dark days and doesn't oxide without the neeed for silicants or phosphates.

But see the problem is I know this instant protection thing is no issue on a Dexcool FF vehicle. So your reasoning for dismissing PGL aren't really substantiated. Besides, probably Dexclones are the most sold coolant and being put into cars that were never FF with it and being mixed with G-05 and Asian. I'm not going to keep debating the point. But your opinions on PGL (and Dexcool for that matter), and that G-05, and silicants and phosphates are the end-all-b-all aren't fully substantiated whether you thinks so.

The real issue I take with you is you twisting my, and sayjac arguments, and saying I'm reasoning that dexcool is good for putting in everything. I can concede when you make a good point, but apparently you can't and have your mind-closed on the whole anti-freeze discussion.

OK now that is just dumb. Field service shows Deathcool protects well? RIGHT. There have been stories of mechanics out in the field finding Deathcool damage in lots of GM vehicles. My links back up everything I have been trying to tell you. Did you actually take the time to read any of them? I am starting to wonder.

GM wanted a coolant that lasted longer. They thought they had that by creating Deathcool. And when it was introduced, there were other choices. G-05 certainly but also Asian phosphate HOAT and there were numerous diesel coolants out there. Chrysler would not have wasted time and money researching Deathcool for use in its vehicles which happened before their decision to go to G-05. Ford is using Asian HOAT in Mazda engines.

There is no assumption to it. You seem to keep pretending that Deathcool problems don't exist when they in fact do. A class action lawsuit that decided in the favor of GM customers certainly proves a problem. You are the one making assumptions. I HAVE NEVER said that adding an inorganic compound to Deathcool would make it better. The only thing that is going to make Deathcool better is its removal from the market. And you are doing a huge disservice by recommending Peak GL in an application that it can't possibly support. The OEM says use a phosphate Asian HOAT. Peak GL doesn't have phosphates in it. Therefore it cannot work in the OP's vehicle.

It hasn't been out long enough to have damaged documented for it. I would really like to see this DuPont study you mention.

I think you mean NEODACANOIC ACID. Some Deathcool versions also have used POTASSIUM HYDROXIDE and SEBACATE. Have these made a difference? Since some people are still having problems, perhaps not.

Well if you are of the belief instant protection is not needed in a cooling system then I have no idea what to tell you. I guess all those water pumps that have been in Deathcool systems with cavitation damage on their impellers and those running a coolant with silicates or phosphates or both that didn't have this damage was all a figment of my imagination.

There is no twisting to it. You are both recommending a coolant that cannot be perfectly fine in an OEM application requiring phosphates. And you keep dancing around this fact even though I have already made numerous good points for not using Peak GL. You keep saying it is fine but you cannot substantiate that claim. I have already linked to several Asian automakers earlier who say to stick with their OEM phosphate coolant or use an equivalent that has phosphates in it such as Zerex Asian. I am almost positive you have not taken the time to read any of the links I have posted.
