when the car turns off, suddenly the guage will (sometimes) go all the way to the hot position... but when you turn the car back on, the guage will move back to the position it was in
is this normal? is it going ot cause a problem?
thanks

Looks like your thermostat is not working properly, or something is blocking the proper flow of coolant. Last time I had a similar problem in a 1990 Taurus, the thermostat had fail in the almost closed position. You can check by feeling the upper radiator hose while the engine is running, and just after shut down. If the hose is hot the thermostat is open and allowing coolant flow.It should also allow some compression. If it is cool and compressible, it suggest it is most likely closed and not allowing any coolant flow. Shut the engine down and observe the temperature and hardness of the upper radiator hose. If it becomes really hot and rock hard, you most likely have a thermostat stuck in the closed position.
