Help with operating temp ?
any body know what the normal Operating Temp is for a V6 4.0, 5 Speed with No AC ? (1992 Ranger ) Haynes says opening temp for the thermostat is 192 F I installed an aftermarket mechanical Temp gauge due to the instrument panel gauge failure. I'm reading about 194 f (90 C) on the gauge. Haynes says Fully open should be 226 F. Never seems to get there. The Truck runs just fine but I'm worried I may have a Thermostat problem. What do you think ?
