The engine coolant temp sensor is in the assembly that the pressure cap (radiator cap) goes on. it's under the part that the cap goes on, closer to the engine block. you can see the wires and the plug going to it. here's the remove and replace step by step:
1. disconnect battery negative terminal (they always tell you to do that when you work on electrical parts)
2.partially drain cooling system below level of ect sensor
3.disconnect ect sensor
4.remove ect sensor
and to reinstall
1.install ect sensor torque to 168 in-lbs
2.connect sensor electrical connector
3.connect battery negative terminal
4.refill system with coolant
hope that helps

Why is My 04 PT Criuser running hot and there is coolant in the radiator ?


check your cooling fans make sure they are working, to do this start your engine and turn on the ac the cooling fans should be running, if it does the next thing to check is the temp sensors, to do this turn off the ac, while the engine is running keep an eye on your temp gauge if the dial is going up above normal or at the point where you say the engine is running hot check if the cooling fans are running,
1) if not running, cooling fan sensor is not working, replace
2)if running, thermostat is shut, the thermostat regulates the flow of coolant in the engine it is fully open at normal operating temp and close if coolant is cold, replace

Radiator fan not running while car is on


There could be a number of reasons why the fan is not coming on. First of all, it will not come on until the temp reaches a level necessary to have it on. In addition, if the a/c is on, it should be running at all times while the a/c is on. If your car has a/c, turn it on and check to see if radiator fan is running. If not check the following, coolant temp sensor, radiator fan relay fuse, radiator fan motor, coolant fan switch and temp sensor. Start with the easiest, the fuse and work from there. Most switches and sensors can be tested with a simple ohmeter.

Fan is not coming on and car is overheating


Fan not working. Check connection under vehicle. Very common connection is bad. Are has been pulled loose from someone hanging a droplight on it while changing oil or working under PT. Run a hot wire directly to fan to check high side and low side operation. If operating and connection is good. Check temp sensor located by radiator fill cap not overflow. Has a single wire. Relay is in fuse box under hood. The fan connection can be cleaned and will work for a while. But I have found it comes loose in a short amount of time. I just cut the connector off and install aftermarket. There is a lot of over heating problems with PT.

98 Honda civic cx over heating when stopped in traffic - I went thru cooling system, replaced hoses, thermostat, fan, radiator cap. After that stated to overheat on freeway after about 40 miles. pulled...


Unplug the fan on sensor. It should have one green wire and one black wire. Use a paper clip and jump the two wires. Turn the key to the run position, the engine does not need to be running. Does the fan come on? If not check the green wire for 12 volts and the black wire for ground. If there is no ground than run a new ground wire. If the is no power check the heater/air conditioning fuse in the under dash fuse block. If there is power and ground make sure both the cooling fan fuses are good and both the cooling fan relays are good.

The cooling fan does not turn on when my 96 Chrysler Concorde when the engine gets hot...where should I look for the problem?


Somewhere around the flange of the engine cooling radiator is a thermostat that opens and closes a circuit for the fan, but first check the fuse box in the engine compartment and look for the engine fan relay fuse... Check it out first!

Hi i just brought a buick century 1998 and well is overheating and i dont know what it could be?


It could be many things. Low coolant, fault thermostat, a blockage in the system, worn or broken water pump impeller, slipping belt on water pump pulley, the cooling fans may not be operating (this could be a faulty temp sensor, fuse, relay, wiring or the fan motor itself).

Radiator fan not working replaced relay,temp


You didn’t mention replacing the temperature sensor located on the block in the path of the ‘cooled’ coolant.
I can’t tell you any closer where to look for it since you didn’t specify which engine you have.
This device is a solid state item called a thermistor.
With the air temperature around 77 degrees F and a 'cold' engine, it should measure about 10,000 Ohms and hot, around 1,200 Ohms while disconnected from its mating connector.
With the ignition on, and the connector disconnected from the sensor, you should measure about 5 volts coming from the ECU.
If this has failed, the ECU is not getting the right info back from the sensor and doesn’t know if the fan is needed or not.

95 grand am radiator fan only runs with AC on


Cooling Fan Temp Sensor is the First thing You Check (with what you have described) Cooling Fan Should ALways come On When The A/C is turned On as A/C Adds A Load to Engine, If Temp Sensor is Faulty it Will Not Give GROUND Signal to ECM >For COOLING FAN >RELAY to Give ground and turn ON The Fan.
There ARE 2 temp Sensors that Serve Different Purposes 1 is for Dash READING GAGE & Or TEMP LIGHT the Other is For ECM or Fan Relay (SAME Thing) you Said>""can disconnect the sensor and fan continues to run" < This Leads me to think you Changed the Wrong One. Not Questioning your Skills Just Here to Help.
TEMP SENSOR FOR 3.1L V6 is Located upper RH rear of engine compartment, near exhaust system. Temp SENSOR for 2.3L Engine is Located in LH rear of engine compartment.
I Hope this Helps Lead you to a NON-OVERHEATING Pontiac.
Good Luck and Have A Great Evening. rejakwilson
