Default Coolant

Pulled the radiator, flushed out and flushed out the garbage from between the fins. New hoses so I am wondering what should I use for coolant.

I see an older post about "Dexcool".

What is the best coolant to put back in a 1990?

Your thoughts are appreciated.

I use NAPA, it has the silicates (says it on the bottle) and meets the 1825-M GM spec. It's green in color and inexpensive.

Your main concern is that you want ethylene glycol with silicates and it must meet 1825-M GM Spec.

GM part # 12378560 (expensive) and Original Zerex are other options.

DO NOT USE DEXCOOL WHICH CAN BE ANY COLOR BUT IT IS TYPICALLY ORANGE OR RED.

Good Luck!

I think I paid under $10.00 for the Napa stuff.

Just FYI, NAPA has NAPA Gold Filters 40% off this month. Not sure if its my area or National

Stopped by Advance Auto on the way home. Prestone and Advance's coolant doesn't contain silicates. Peak antifreeze does. $12.50 a gallon.

The key is to get the stuff that is the old formula. Thanks for the advice everyone!!!
