going from blue coolant to orange? #5123077 06/02/19 01:50 PM

i got a 1995 ford fiesta in the uk, its has a 1.6 16v zetec silvertop engine. car has always been run on blue antifreeze for over 20 years. specs it conforms to are: British Standards BS6580 (2010) and ASTM D 3306 & ASTM D 4985, SAE J 1034, AFNOR NF R 15601. and is Ethylene Glycol based.
problem is that i have to keep changing it out every 2 years and since i do less then 6000 miles in 2 years it seems wasteful and a bit of a hassle for me.

now i have seen orange coolant that is specced as : Full organic long life coolant, 1-2-Ethanediol based – Organic acid technology formula. Ethanediol based coolant, silicate, boron, phosphate, nitrite and amine free, which is a multipurpose long life formulation dedicated to engine which require “. Dex-Cool” coolant Recommended in engine cooling circuit which needs GM6277M norm

wikipedia says 1-2-Ethanediol is similar to Ethylene Glycol. this orange coolant is specced at 5 year change intervals.
is this safe for me to use in my car that has a cast iron block and aluminium head? or should i just put up with the 2 year change intervals and stick to blue?

blue stuff i have been using:

and the orange stuff i have been looking at:

Ethanediol = Ethylene Glycol, the same thing

I woudn't use that orange coolant as it's basically Dexcool, which contains something called 2-Ethylhexanoic acid which can be very bad for cooling systems not designed for it.

I use this in my two Fords : https://www.amazon.co.uk/Comma-XSG4...081029&s=gateway&sr=8-1-fkmrnull

Comma G40

This also lasts 5 years and doesn't have the 2-Ethylhexanoic acid, i use it in my two Fords and it works well!

It works very very with alloys, the mix of Silicate + Organic acid inhibitors is probably the best there is for Alloy or Aluminium, and it also works perfectly well with Cast Iron, copper, brass, solder...

slybunda,

Why are you changing coolant every 2 years on a 1995 Model year car?

I'm with JC1. And I wouldn't use another type of antifreeze. Stick with what came in the engine.

well i bought the car in 1998 so still driving it today. book says (and coolant bottle) to change every 2 years or xx mileage. for me i always hit the age before the mileage.

I would choose one of the long life coolants out there that does not have silicates or 2-EHA.

When it comes to engines with water pumps driven by the timing assembly, I prefer the coolants made for Asian cars. The Honda Type 2 blue coolant is silicates free, contains no 2-EHA and is a five year coolant.

Flush the system well to completely evacuate all old coolant from your system, and refill your system with that and distilled water and you'll not have to worry about it for a really really long time.

What reasoning is behind your preference for Asian type coolant for timing belt driven pumps?

Free of silicates. Asian manufacturers like a silicate free coolant to prevent silicates from causing wear on the water pump. Heavy duty manufacturers for the same reason.

The Honda Type 2 and I believe the Toyota Red/Pink also have no 2-EHA. Exactly where I like to be for an older car with a hard to reach water pump.

I'm pretty sure i've read a study which showed that the claim that Silicates are in some way harmful to water pumps was false.
I'll try to find it.

That's their side of the story. Those making the engines feel differently. No way to know for certain, but there is certainly no disadvantage to a silicate free coolant so I am not seeing any reason to use silicated coolant.

VW went from a Silicate containing IAT formula in 1996 to a full OAT, then in 2012 went to a Silicate containing HOAT, they basically just added 400-500mg / L of Silicate to the OAT they were using, and that is what they use to this day.

I am in fact using VW G12++ Spec coolant, a.k.a G40, in my two Fords, i was using a full OAT coolant before and have noticed a number of small coolant weeps it had in certain places have stopped leaking completely, this is probably due to the fact that Silicates help seal small porosities that would otherwise leak.

This coolant has Silicates, Sebacic Acid, Sodium Benzoate, and some kind of Azole or Copper protecting OAT inhibitor the name of which i don't remember for copper and a pH of around 8.5, with a reserve alkalinity of around 5 IIRC

Silicates are excellent at protecting aluminium and have synergistic effects when used in combination with other inhibitors like Azoles and Sebacic Acid.

I hear you, but silicate free coolant does a perfectly good job of protecting everything, with no drawbacks at all.

Sure, but Silicate can make it even better.
