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!
