Did you make sure that you are putting the themostat in correctly? If you put it in backwardthis can sometimes cause this problem.
stop an engine
Does that mean that you replaced the thermostat AND the sensor? If not, you really need to replace the thermostat. A sticking thermostat can cause temperature swings and potentially overheat the engine. BTW, BMW engines tend to have serious problems when they overheat. Don't let it overheat or you might be buying a new engine.
A bad thermostat can cause an overheat. A bad temp sensor can show an overheat when the temperature is normal.
If the engine is overheating the temp gauge will go all the way to the right and a red light will come on.
check thermostat or water pump, I've had both problems before and it will cause the car to overheat. The temp sensor is on top of the engine right in front of the spark wires. It go's down into the engine.
check thermostat. check engine fan coolant sensor possible locations radiator or thermostat housing. check electric fan working
The coolant temp. sensor could be bad....or the thermostat could be stuck shut.....there are a few things it could be actually
The engine temp sensor is on the front of the engine, next to the thermostat housing.The engine temp sensor is on the front of the engine, next to the thermostat housing.
My 2000 would overheat at idle; in park & slow traffic. Ran normal on the highway. I 1st replaced the fan relay everyone has been blogging about, engine still overheated. Next attempt for victory, I replaced the temp sensor switch; defeated again. I then replaced the thermostat & haven't had a overheating incident since.
Protects, no. The only temp sensor is the coolant temp sensor. The car will run until the engine is ruined if allowed to continue overheating.
If it's not really overheating but you're getting warnings, it's probably a faulty sensor.
check the temperature control sensor....
