randy, i would bet that you have a cracked head. are there any stains on the side of the block anywhere. also pull your plugs, if your burning coolant it will show different then the rest of the plugs. i dont think the cracked man would cause that, mine was cracked and i never had any problems.

Yes, a blown head gasket or cracked head/block could cause overheating, but everyone I have seen continues to overheat at idle. A simple way to check if this is causing your overheating is to start the engine while it is cool with the cap off and look for air bubbles coming out of the radiator as it heats up. A mechanic shop can also do a sniffer test to detect exhaust gases coming out of the radiator. My money is still on a clogged radiator.

A cracked head, block, or blown head gasket that causes the coolant to burn away would also make the truck overheat at all times (because all the water is gone).
I once had an old Buick with one of the above problems (I junked it). It ran like a top as long as I kept water in it. I would fill the radiator every morning. The plugs were dry, the oil looked good, and it did not smoke. But the water in the radiator would just disappear without a trace. And when it did, of course it overheated no matter what speed I was going.
