Ql have an '88 Toyota pickup with a 22RE that continues to try to overheat. The temperature gauge goes almost to the overheated mark then falls back to normal. The truck does this every morning when I crank it up to go to work. It tries to overheat even faster if I turn the heater on. It only does it once a day unless I allow the engine to cool down again. Could this have to do with the head gasket or something serious?

A I think you have a blown head gasket. Check your oil for coolant. Is the oil brownish white and frothy? Or let the oil sit and drain it, then you'll be able to see coolant in the oil that comes out. Also do a leak-down test on the engine.
