What type of change interval would you recommend for mostly city driving? Manual says every 32 km/20 miles. Is that a bit aggresive considering this is labelled as "long-life coolant"?

From what others have said, the toyota red and pink coolant are very good. I have the pink (super long life) coolant from the factory in my corolla. I am planning on draining/refilling with pink in either 2 years or 50K. Good preventative maintenance

like any coolant the key is the change it every 20-50k miles. if you live in severe climats whether cold or hot i would go with 30k miles whether it says long life or not. this will keep from the need of flushing. just drain and fill. its easy...


-- btw you can use the green prestone (any make, any model) coolant in toyotas. its cheaper than yota stuff. just change it out every 30k. it will be fine.....

Toyota Pink = 100k (first change), 50k thereafter. I plan to drain and refill every 50k. Prediluted 50/50

Toyota Red = 30k. I flushed it at 30k and 60k. Just plan on drain and refill every 15k here on out. Must add water.

Toyota's current red coolant is an OAT (Organic Acid Technology, like DexCool), which like most Japanese coolants contains phosphates but no silicates.

It differs from DexCool primarily in that it lacks 2-EHA, which Toyota seems to believe creates some problems with gaskets.

From what I've seen the current Honda Coolant is about the same despite the color difference.

If you own only Toyotas their coolant makes a lot of sense.

Universal antifreezes, which are usually some version of a DexCool clone, often contain 2-EHA, which is something of a no-no.

In my own fleet, which includes a Toyota which came with the red fluid, a Hyundai, and an '06 Malibu I've settled on G-05, which is factory fill on Ford, Chrysler, Mercedes, and some others.

The slight trace of silicates doesn't seem to cause any problems in years of use, it avoids the low coolant problems that arise with DexCool and its clones, it's long life, and it's pretty much as close to a universal coolant I've been able to find.

DexCool and Toyota Red must be pretty close, because Toyota uses the red/pink in the Matrix; and GM uses DexCool in the Pontiac Vibe, which are the same cars with same engine.

The phs of Prestone green and Toyota red are 11.1 and 6.8, according to a virgin coolant analysis on this tread. 1-7 is acid, 7-14 alkaline. So there is a basic difference in the chemical composition of the two. Levels of silicon, boron, molydenum, and phosphorus are also quite different. I do not think they are interchangeable and do not think green is compatible with Toyota.

dave to your dismay people have been running green coolant in yotas for years and years with little or no issues. the key is the change the fluid regularly 30k miles or less since it isnt a long life coolant.. also use distilled water

I am not dismayed at all. The fluids are manifestly not the same. Where is your data?

I have been using regular green in my Toyota Avalon for 8 years (as a matter of fact, I just drained and filled it Friday) and never had a cooling problem- no leaks, no nothing. Thats just my own experience. Car is a 97 Avalon

My Dad has been useing Dex Cool in his 1995 Tacoma for a long time. Recently I replaced his thermostat and flushed the system. Since the water here in Michigan is hard I decided to use Zerex G-05 this time around. THe water was softened tap water. So far no problems at all. As long as you do not have coolant that pass's through plastic pieces I do not think their is anything wrong with useing Dex-Cool in a pinch. I prefer G-05 because I am familar with it and know that it works well even with hard water and that it is safe to use even when coolant pass's through plastic parts!

So as long as you are flushing I would think G-05 or Pentosin would be my first choices followed by all others.

JohnBrowning:

Is that G-05 the Dex-Cool compatible stuff? Or their other universal A/F?

Cheers, sounds like this could be a good substitute.

G-05 is NOT Dex-Cool compatible. G05 uses Silicates and Borates.

Thanks for the heads up.

Would you choose to run a previously-filled Dex-Cool vehicle with G-05?
