Question about 2001 Jeep Grand Cherokee
Engine overheats when idling in heavy traffic.had a new radiator fitted-unfortuneatly mechanic fitted an aftermarket chinese made product without my knowledge,charge genuine price though?? fan has been recond but problem still exists.mechanics answer to my problem is "should buy a decent car as Jeeps are a heap of ****" How is a women supposed to get her vehicle serviced properly with an attitude like that,cheers Sue
It could be the thermostat which is cheap and easy to replace. The mechanic should have replaced this along with the new radiator.

Had this problem and one thing that even Chilton manuals only show in fine print sorta say is that Jeep cherokee has a relay sensor for the coolant fan usualy right behind the passenger or driver side headlight you may have to remove the bumper also its rather easy.Its a liitle black box thats screwd down on the panel just unscrew it unplug it replace mine ran me around $60.00.Before I learned about this after replacing the thermostate and just about to rip out the water pump my buddy told me about the sensor after replacing over a year ago no problems.

Have you confirmed the fan has a good ground, sounds like you have eliminated the issue of 12 volts, when you turn on the fan then the AC does the compressor run? if the compressor runs pull the plug to the fan motor and check to see if has 12 volts with a test light, wait for moment because the fan may not run until the AC system pressure reaches a certain pressure point, this means that even though the compressor is running the fan may not always run, There is a quick test for the fan circuit, disconnect the fan sensor at the thermostat housing, the fan should come on, this is failure mode, so if the switch goes open the fan will run to keep the engine from overheating , let me know after the tests are run.

SOURCE: no heat when car not moving
Ok, judging from what you've said it sounds like a vacuum issue. The temperature controls are activated by vacuum which is produced by the engine. Look for small hoses that lead from the intake manifold to the firewall, check them and make sure they are not broken, disconnected, or leaking. The vacuum directly controls the doors inside your dashboard which push the air to the heater core. Also make sure that the coolant hoses going to and from the firewall are hot. If all that checks out, then the controls inside the car may have gone bad, or may have become disconnected from the vacuum supply, or the actuator door inside the dash is stuck or broken.

Yes you have to check your pressure with a mechanical gauge first. If the pressure reading is good replace the oil pressure sending unit. They are known to go bad, and oil pumps going bad is rare.

Check the fuse for the fan and use a test light to make sure that the circuit is functioning. Warm up your car then feel along the top and bottom of the radiator to check for cold spots. If you find any then you may need to replace your radiator. If your heater isn't currently working it may be that since it is a part of your cooling system.
