Is vehicle actually overheating? Could be a bad temperature sending unit or gauge Check temperature with a thermometer If thermostat does not open vehicle will overheat


Inoperative cooling fan(s) Bad thermostat Bad fan switch sending unit Bad fan relay Blocked radiator cooling tubes (internally)


Temperature Gauge Sending Unit The sending unit is located in the front section of the manifold in the vicinity of the thermostat.


If it's not blowing out all of the coolant in a short period of time, you probably have a bad water pump. On the other hand, if you ARE blowing out all of the coolant, it's probably a damaged head gasket.



The coolant temperature sensor is near the thermostat outlet at the front of the engine. You are facing the engine. It should be located to the right of the thermostat outlet. The sending unit on the left of the thermostat outlet, is the temperature gauge sending unit.


Temp sending units in general (not always) are usually found close to the thermostat.

Didn't mention the year or engine size but temp sending units are generally found close to the thermostat.

I had the same problem. relaced the tep control sensor and sending unit and it worked. One is located next to the thermostat housing and the other is further over on the intake.




check thermostat and temp sending units there should be two



One is the temperature sending unit for the gauge and the other is the sending unit for the computer. The housing is called the water outlet. There is a plastic bypass valve that melts when the car overheats. It is inside the water outlet. If you changed your thermostat and still get no heat you need to replace this water outlet housing. There is no way to fix the plastic bypass. You have to replace the water outlet housing.
