Question about 2001 Jeep Grand Cherokee
I have a problem with my Jeep overheating and the fan won't come on. We have checked that the fan moves freely, we've replaced the temperature sensor, thermostat and the fan relay. We even jumped the fan to make sure it works and it does. We're running out of ideas of what the problem could be. Could you help us with this problem.
I need to know what all has to be taken off, the easiest way, to replace a radiator fan motor for a 2001 grand cherokee?

Remove right front headlight cut out the plastic right below where the headlight rest on. Just a 4"x4" square and take out the plastic there you will see the relay,2 screws and remove the relay. Patch the hole with duct tape and put the headlight back, no need to remove the grill or bumper.

Are you sure you replaced the radiator fan relay? This relay is a solid state relay and is very hard to get at. It is very common for these to go bad. It is located in right front corner of the engine compartment behind the right headlight. You can barely see it let alone get your hand on it. It has two 5/16 screws holding it down. The PCM sends a signal to this relay telling it to turn on the fan. Having said all this I am assuming that you do have an electric fan. Some grand cherokee's have a hydraulic fan depending on year and engine that uses power steering pressure and a solenoid to actuate it.

I had the same problem. Replaced the fan motor , thermostat and relay. Worked great for about two weeks then started over heating again when idling, i.e. the fan motor was not coming on. While the engine was hot I reached my hand between the battery and fan to check the connector from the fan to the relay. When I wiggled the connector the fan motor would run until I let go. One of the wires was broken behind the insulation in the top of the connector. And naturally these connectors are usually dealer items not available at your chain auto parts stores

I did all this and it is alot easier to take out your right headlight but keep in mind that you have to remove the grille which is attached to the bumper . the relay is right there its square with 2 (5/16) bolts .. unclip it and remove ...

100 degrees f? That is way too cold Either you have the wrong thermostat or it is wide open. 180 degrees is nominal and give you the best performance.. With AC on, expect 190 to 200 degrees. We are talking farhrnheit and not ccelsius, correct?

suggest that you rent a pressure tester from auto zone or advance auto and preform a pressure test on your cooling system. follow the instructions on the test of pressure to your cooling system,also check for coolant leaks onto the ground from radiator area. may be bad water pump,broken hose,heater hose,upper radiator,lower radiator,or a bad radiator itself. a simple pressure tester will reveal the coolant leak. but make sure to follow the instructions with the pressure tester,as you can damage your coolant system otherwise. thank you for choosing fixya.com
