I know my 5.3 was a little clogged up from dexcool. There was just a bunch of restriction. I bought the best coolant flush I could and it actually made it stop. It used to overheat with the a/c on.

How is yours overheating. Under what conditions? How many miles are on the truck? Does the a/c have clogged fins in front of the radiator blocking air flow?

Does the temp just keep climbing when you start the truck of just spike when you least expect it? Or under a load? Only on a hot day?
