Coolant recommendation
Is there any new recommendation on coolant to use? I have used 50% Havoline Dexcool with distilled water and a bottle of water wetter in the past and is it still the way to go?
Thanks

I recall that DexCool is not recommended. If you switch, be sure to fliush; Dexcool and Zerex may not play well together because of the sodium silicate in the Zerex.

I have been swapping over to Zerex Go5 seems to be a good choice as a lot of others have as well,
get it at NAPA pick up 2 gallons of coolant,
and 2 gallons Distilled water at the supermarket

If swapping to G05 from something else, make sure to do a complete flush, to include drain plug removal. I would assume would be doing that anyway.

From what I have been told, and have learned from chemist, you would want to use an extended life coolant that doesn't have silicates. Silicates can cause pre-mature water pump failure. Texaco/shell originally developed the extended life (OAT) coolants, and performed many long term tests with them. I believe the G05 has silicates?

I use Amso...
Wait.
I use whatever is silicon- and silicate-free, including Dexcool, from my Friendly Local Auto Parts Store. No problems.
There was a Decool issue years ago (5+) and it's resolved. BTW - "Dexcool" isn't a specific brand but a label to show compliance with GM specifications. Just like "Dexron" is for ATF.
