Hy Trev, you're checking everything else, why not the belt tension, it's not rocket science? Just a note to everyone, if your car starts to overheat in traffic, slip it into neutral, and raise the r.p.m. slightly, this increases the rate of coolant flow through the rad, and the engine fan speed as well. A stuck thermostat will just let the engine get hotter and hotter, the fact that the engine does cool back down says the thermostat is functioning. We could put a 160 degree thermostat in it and give you 20 degrees more wiggle room.
