If fuel is in the oil then you may have a head gasket or a piston sleeve is crack to rule this do a compression test and check for cracks and leaks on the outside of the car or truck.
Did you make sure that you are putting the themostat in correctly? If you put it in backwardthis can sometimes cause this problem.
The coolant sensor moniters the coolant temperature. A faulty thermostat could cause the engine to run cool.
A defective thermostat can cause the engine to overheat. It can also cause the engine to not reach full operating temperature if the thermostat is stuck open. It is possible this could set the check engine light.
Answerno thermostat but only temporarily.A thermostat functions to regulate the flow of water between the engine and radiator.On an average outside temperature day (75 degrees), "no thermostat" would result in (1) the engine not reaching operating temperature in the normal engine warm up cycle time and (2) much later in the cycle the engine would overheat caused by the water not remaining in the radiator long enough to cool down. More extreme outside temperatures would impact the previous results.No thermostat or a defective thermostat that is stuck open. Also could be a deffective coolant temprature sensor. Or air bubble aroune the sensor on some cars.
No it will not.
The first thing that I would check is the wiring and the temp sensor @ the engine. Sorry but I do not know where the sensor is located on the engine. Usually they are not too hard to locate. i would replace temperature sender usual located near front of engine near thermostat housing
Yes, just about any sensor on the engine could cause a no start.Yes, just about any sensor on the engine could cause a no start.
the most common cause would be a stuck closed thermostat.
Not likely. A bad O2 sensor would illuminate the check engine light and the engine performance would suffer.
Driving through flood water would cause the ignition to fail and stall the engine.
The thermostat control engine temperature. If it fails the engine can run hot or cold - that would happen long before over-heating caused the engine to stall.
There is an engine temperature sensor that operates the cooling fan.
yes sometimes cause if it fails open the temp sensor will kick the light on tellin its too cold or opposite if the thermostat fails closed
A bad thermostat can cause an overheat. A bad temp sensor can show an overheat when the temperature is normal.
this is normal for this engine, in fact anything short will trip a check engine light. the cause will be a low coolant condition, a thermostat stuck in the open position or a bad coolant sensor. this is normal for this engine, in fact anything short will trip a check engine light. the cause will be a low coolant condition, a thermostat stuck in the open position or a bad coolant sensor.
If the thermostat was not installed correctly, the housing can crack but it would leak engine coolant not oil.
I would suspect the thermostat is stuck open. Replace the thermostat.
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.
The thermostat is failing.
Cold engine, extremely cold weather, malfunctioning temp sensor, malfunctioning thermostat.
Have you tried replacing the o2 sensor? Perhaps the thermostat as well. My 94 has 94000 miles. My O2 sensor was bad causing the engine to run too lean......sounded like it was choking itself out. Also, my thermostat needed replaced and that too helped it run better.
you looked at it Timing out of adjustment can cause overheating.
It could cause the check engine light to come on with a code concerning cooling system/thermostat performance.It could cause the check engine light to come on with a code concerning cooling system/thermostat performance.
