    If OAT based coolants are good, wouldn't it stand to reason that HOAT based coolants that seem to be the recommendation of choice for a lot of European vehicles that have aluminum components would be an even better choice for 5.7L in a 97 K1500. I don't care what anyone says, I have personally seen the damage Dexcool does even with following the manufacturers recommendations.
