Car has new thermostat installed very recently. Was working before I pulled old engine. I just pulled my engine and replaced it with another engine. I have a lisle coolant funnel on the crossover access, have the radiator cap removed and the front of the car on jackstands. Car heats up to normal temp on gauge, fans come on and I have the heater on high and have hot heat in car. hose below thermostat will not get hot! Has anyone else had issues getting thermostat opening? I dont really trust my gauge because Ive had the car overheat with the gauge reading normal before. its an 05 GT btw, I think they changed thermostat location at some point on the 3 valves. Anyone have any ideas? should I take the car on a short drive and see if that helps?
