Overheating Problem
Well, after head gaskets, a thermostat, two water pumps, and a new radiator the culprit to the overheating in my situation "boiled"
down to the heater core. The issues I was having with the temp shooting up and only being able to be dropped back down by increasing the RPM's was due to a heater core issue. After driving it one night and experiencing the same old temp. spikes, I cranked up the heater and watched the temperature skyrocket. The next day I bypassed the heater core, and it solved the problem.... For the first time in 3 months, the temp stayed in the normal operating range and did not fluctuate. I was a little suprised it was the heater core, becuase I was not getting the typical signs of a clogged/bad heater core (smell and windows fogging up), but since this cooling system incorporates a constant flow design to the heater core, I guess it would make since that even a small restriction in the core will lead to overheating. Anyway, I hope that anyone else with the same problem will try bypassing the core, and seeing what happens.
One a side note, since I already dumped a ton on money into this car, am not going to be getting the heater core replaced for awhile. Does anyone know how many watts the cigarette lighter can handle, as I will be buying one of those portable heaters that I will have to stick up on my dash this winter.
