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?

It runs fine most of the time till you hook up a trailer and drive. trailer can be empty or full does not matter but if you start to clime even the slightest hill the temp starts to go up slowly but if you let off it cools down. It happens on cold and hot days. As for mileage it is 180,000. NO clogged fines on the ac, or radiator.
