What is Dex-Cool compatible?
Posted 14 January 2004 - 01:21 PM
What can I use as a substitute. I see Prestone makes their extended life stuff that is compatible with Dex-Cool and I also saw Havoline is compatible.
Any pro recommendations? Anything to stay away from?
I don't think there would be a difference vs. using the GM stuff. But, I just want to make sure.

I know someone that owns a company that rebuilds those old Cadillac 4.9L pushrod V8's. These are weird wet-sleeve engines with an aluminum block and iron heads, backwards from the norm. These engines had major combustion chamber leakage problems due to corrosion and such. Anyway, he said they will ONLY use genuine Dex-cool, NOT Prestone's Dex-cool compatible stuff because it doesn't have as good anti-corrosion properties as real Dex-cool.
Anyway, I personally would avoid the Prestone stuff. Not to mention, I used to run Prestone green coolant in my car and the head gaskets corroded from the inside out despite having changed the coolant annually.

GM Dexcool was originally made by Havoline. You can get the Havoline stuff and it should work just fine. Just make sure to use distilled water to mix.
