Fan relay is located under pass headlight. Remove light assembly, use 2 1/2 " hole saw to drill hole in plastic housing ,3"from back wall, 3'' from left side.This will put you right over relay. Unscrew two bolts,replace. Relay was $40.... dealer wanted$350 to remove front bumper to replace it.

The Pulse Width Modulated (PWM) cooling fan relay is located below the right headlamp behind the bumper fascia (Radiator Cooling Fan Relay Location).

  1. Remove front bumper and grill assembly.
  2. Remove 1 support bolt near front of reservoir (Radiator Cooling Fan Relay Location).
  3. Remove 2 reservoir mounting bolts.
  4. Remove reservoir from vehicle to gain access to vacuum hose (Vacuum Reservoir Removal/Installation). Disconnect vacuum hose from reservoir fitting at rear of reservoir.
  5. Disconnect electrical connector at relay (Radiator Cooling Fan Relay Removal/Installation).
  6. Remove 2 relay mounting bolts (Radiator Cooling Fan Relay Removal/Installation) and remove relay.

Change the sensor, but it will run hot like that if you are not moving fluids across it. It is basically measuring air temp for a minute. Could be a totally stuck thermostat. Change both. That cooling system is critical on a cherokee.

2000 Jeep Grand Cherokee with a 4.0L engine... the temperature only rises to about 150 degrees and stops... sometimes lowers a bit even at highway speeds. Normal operating temp is about 210-215 degrees. ...


The thermostat controls the temp of the engine. The temp sensor tells the gauge what temp to display. If the heater is still putting out a lot of heat then it may be a false reading temp gauge. If however the temp is noticibly cooler then replace the thermostat. A stuck open thermostat would also cause the engine to warm up slowly. check for a loose/dirty connection at the plug on the temp sensor.

The clutch on the fan is defective or your radiator is clogged due to mileage and age. Not sure what engine size or mileage is on this vehicle,but these are two basic areas to start with. Worst case would be a head gasket issue.

Replace the cooling fan clutch. It is the silverish round device that the fan attaches to. This component is heat sensitive and will only function correctly when hot. They are known to fail over time. Also inspect the radiator for good coolant flow. DO THIS when engine is cold only or have a shop check it out for you.

1998 Jeep Grand Cherokee Engine Stays Cold


If you have verified that the dash temp gauge is correct by checking temp of coolant in radiator,yes your guess would be what i would change,the engine needs to have a 195degree thermostat in it.195 degrees is what the computer is programed to see as normal running temp.

STOP DRIVING.

Go to a shop and ask for a cooling system pressure test.

After they pump up the coolant system,they will point out is there any INTERNAL or EXTERNAL leak(s).


Internal leak is the first sign of blowing head gasket. (NOT GOOD)

External leak can just a small hose.


Start monitor cooling loss.

Start monitor the oil level

Change the thermostat and gasket.

The temp sensor is cheap. Change it at the same time.

Use 60/40 coolant mix is you has high odometer reading like 160,000+ miles


DO NOT ALLOW the coolant and oil cross mix.

As soon as it mix,you are ready for a majot head gasket repair.


Good luck.

Your thermostat is stuck closed. It needs to be changed right away. By the way the operating temp on that motor is 160 degrees so you are running hot you have just been lucky so far. Good Luck
