Re: What is the best rad flush for '05 Chevy?

Just a tip....Use distilled water when mixing your coolant, Using ANY other water will contaminate the cooling system with chlorine, fluoride, Iron, & a host of other chemicals & minerals.

Ive run several cars/trucks on 50/50 Dexcool/distilled water for a full 150K with no problems.
