Most likely cause is the temp sensor that controls the fan is reading improperly causing your fan to constantly run. Although being stuck on is alot better than not coming on at all which is usually the case. Replace the sensor and you should be all set, but if you are mechanically and electricly inclined you could re-wire the fan to a switch on your dash and control it at will, just a suggestion as a switch is probably cheaper than a sensor.

Good Luck
hopet his helps

1994 buick skylark overheating why


Check the coolant level.
The radiator must be full, coolant should be mix of 50/50.
If it is full, and stays full when overheating, the most common cause is a defective cooling fan.
One of your electric radiator fans is for your A/C and one is for the radiator cooling
Any time the temperature gauge/ or red light comes on, that fan should be running.
Raise the hood and look the next time it overheats, and if no fans are running, you need get it fixed quick, lest you blow a head gasket.
The problem could be either the electric fan motor, or the sensor switch that screws into the engine block.
If the coolant stays full, and the fans are running, you may have a stuck or closed thermostat.
God bless your efforts.

My 1991 ford f250 engine temp gauge never reaches normal range for very long. Most of the time it stays below normal.


assuming you are not low on coolant, then the only things that can make it too cold is if the thermostat is open all the time, or the electric fan stays on all the time.

It is easy to see if the fan is on all the time or not. If it is, it could be the relay or the sensor. Unplug the sensor at the radiator, and the fan should stop, if not then the relay is stuck.

If the thermostat is open all the time, both hoses to the radiator will start getting warm at the same time. They shouldn't. The thermostat side should stay cold until the thermostat opens, then get hot all at once.
That 3 bolts off thermostat cover, put it in not water to see when it opens.
Or just replace it since they are cheap.
Use a new gasket and sealer, or O-ring.
Don't put it in upside down. expansion pellet goes towards engine.

Electric fans run alltime and tempgauge stays on cold .already replaced coolent sensor.


You need to have the cooling system serviced. Drain the coolant, replace the thermostat which is more than likely stuck open, flush the system, and refill with a 50/50 mix of the correct antifreeze and distilled water. You may also need to replace the thermal sensor for the cooling fan if it stays on all the time. Know that when the A/C is on, the fan runs continuously. So make sure the A/C is turned off.

Does the fan on a 94 jeep grand cherokee run all the time ?


The mechanical fan runs all the time but only engages full when it is hot. The electric fan should be on full time only when the a/c is on or the engine needs extra cooling. If the electric fan is on all the time, likely either the relay is stuck in the on position or is getting bad information from the computer or sensor.(or someone modified the system to make it stay on)

Replaced the 2 O2 sensors in front of engine. was wired wrong because dealer that i got car from years ago cut from engine harness, timing belt broke replaced it and the water pump. car started to over...


is the electric fan coming on?if not it will do exactly what you describe.
once in a while at a steady 40mph speed,it may cool down.
there is a fan switch on the radiator that drives a fan relay.
you can wire 12v to the fan and see if the car stays cool,if you can not figure out the electrical.

if you changed the sensors on the head , then the fan temp sending unit on the fan assembly is faulty. it's sending a false reading to the computer therefore keeping the fans running replace this and the proble will be resolved
