Since you have already changed everything that you have, I can not think of anything new that might cause your Jeep to overheat. Are you going by the meter in your vehicle or doing separate temperature measurements? I had a defective temperature gauge that caused me to chase my tail till I did separate measurements.

    How do you go about getting accurate temp readings if you suspect a faulty gauge? What if you already replaced the coolant temp sensor?

My 2000 Jeep Grand Cherokee is overheating. Where should I start, the fan is running.


Check the water level in the RADIATOR, not the level in the RESERVOIR.

If that is fine, it may be a stuck thermostat.

2000 jeep grand cherokee is overheating, replaced the radiator, face works, water pump seems to be working, replaced the fan relay. thinking of replacing the thermostat and wondering what it could be if...


If the fans don't come on to cool the radiator then maybe it's the thermal fan switch, which sends the turn on signal to the fan relay, that might be bad.

It keeps running hot. I have a new radiator, new thremostat, new water pump and new fan. Is there a relay switch or fuse somewhere


There is a radiator fan relay switch located inside the passenger headlight enclosure. You may to remove the front grill to get to it or cut a hole there and you will see the relay.Also in the fuse box under the hood there is another fuse. It might be labeled TCM. Hope this helps.

The car keep overheating, there is water in the radiator and the resevior tank 2000 jeep grand cherokee i check the oil their is no water found in the oil the water from both unit stays full


Sounds like your thermostat is stuck closed. Shouldn't be more than a $20 part from autozone and is simple to replace. Follow your top radiator hose to the motor and it will connect to your thermostat housing. Disconnect the hose (antifreeze will run out) unbolt the housing, and replace the old thermostat. Refill radiator and bleed the system.

Overheating while Eating


Bad themostat, dirty radiator (the front of it), corroded interior core of the radiator, weakening water pump, bad radiator fan.....just to name a few. More than likely? Low antifreeze level, or the thermostat.

I have an intermittant overheating problem with my 2000 jeep grand cherokee. It only happens when sitting in traffic or at a drive thru. I have replaced the thermstat, fan relay module and coolant sensor....


Once the radiator fan operates when hot, then that part of the system is fine. It definitely sounds like the radiator needs flushing out. I had this same problem with a taurus and I flushed the radiator out for a good twenty minutes; you should have seen the stuff that came out! Disconnect the lower hose and drain **** then stick the garden hose in the radiator cap. I would surely do this.
