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.
Not directly.
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.
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
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.
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.
There is an engine temperature sensor that operates the cooling fan.
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.
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
