    I gutted the A/C and heat components from my truck recently. The heater hose ran from the intake to the heater core, through the heater core, out a second pipe and into the radiator. I was wondering if hooking the hos from the intake to the radiator could be one of the gremlins causing my truck to oveheat?

    Interesting question.

    I'd suspect it can't help. The intake is an outlet (that is pressurized hot coolant) and the radiator inlet for the heater is on the "cold" side of the radiator.

    I can imagine that it might make a difference in engine temp, since the water that would normally be cooler (after passing through the heater core and long coolant lines) is coming into the radiator much warmer than before.

    If you've got room and the water pump has it, you could swap the nipple on the intake for the plug on the water pump. That's an unpressurized (and "cold") tap.
