It sounds like it may be your electric cooling fan. When the car is sitting idling does the fan behind the radiator ever come on? If not then this is your problem. Your car doesn't overheat when it moving because you're passing air through the radiator with the movement of the car. The problem could be the fan itself, the fan relay, or a temperature sensor.

Coolant sensor keeps saying bad would that cause it to over heat jeep laredo 97 grand cherokee


Yes, cause that sensor operates the electric cooling fans by the radiator, if those fans or fan don't come on, the radiator can't cool down as quick and causes the engine to run hotter.

you electric fan probably isnt working with vehicle warmed up lift hood and watch temperature gauge when it starts to over heat check to see that fan is working if not it could be the fan relay or fan itself if the fan does turn on its most likley the thermostat

2003 Grand Cherokee Overheating


This might help you as it looks as though you have an electric fan to cool , there should be a sensor on your radiator hoses upper and lower.they are actually switches triggered by the coolant temperature in side the hose. While your Jeep is sitting idle, shut off the AC as it adds to the heat off the engine not to merntion useing more gas. you should make sure both high and low speeds on the coolant fan work. good luck if this does'nt help check out the post, with more, on the 1995 Jeep heating up..

Many cars have a thermoswitch threaded into the radiator that activates the fans when engine exceedes normal optimum opperating temp. This sensor may have failed , or one of the 2 wires that go to it may have come unpluged or broken

follow top radiator hose from radiator to engine wear hose ends, it will be clamped to whats called the gooseneck, thermostat is under that. you will have to drain coolant, not all, maybe 1 half gal. before you remove it. 2 bolts new gasget new thermostat, just remember spring on new thermostat goes in engine.

I have a Nov 1990 Cherokee jeep Laredo with a heating problem. The radiator and thermostat have been renewed with the problem still has'nt been licked. Any suggestions for what to do next? Dave


If it's lack of heat, it could be the heater control valve. If the jeep has alot of miles on it, the heater core should be reverse flushed.

1995 jeep lalredo 4x4 keeps geting hot


The problem with these jeeps is that the older they get the more clogged the radiator geats.
The radiator in the Cherokees are only a single row of tubes.
You can try to flush out the radiator, but replacing it with a heavy duty type is probably a better option.
Your car is not getting enough flow to cool down the engine.
Also you want to check that the electric fan is coming on. There is a coolant sensor in the radiator.
