well the truck overheated on the way home from the inland valley, got it cooled off and it seemed to run fine called the hook and had it towed home anyway didn't want to risk it. Got out the radiator pressure tester and although it was high at first it went back down when the thermostat opened and it seems to run at its normal temp so I think the heads are okay, at least for now. My question is does anyone know of a larger radiator or at least a better one that would fit the truck? I figure that might help a little with the cooling plus the fill neck on mine is cracked, not leaking yet but probably will soon. Oh and my truck does have air conditioning if that makes a difference. Thanks guys.
