Jeep Cherokee and Grand Cherokee Overheating
I recently went to the mechanic to get my engine belt replaced. The next day I took it out to discover that the car has begun to overheat. I dont know what the issue could be. There is no coolant leaking either. Any thought as to what the problem could be and what I can do to fix it?

if over heating when stoped would think that elect fan not running right or up to speed if me would replace elect fan
dealer should be able to check if have exaust gases in colent sure sounds as if have bad head gasket
have they checked raddiator flow so as to see if raddiator is pluged?
For anyone having overheating problems with their Jeep Grand Cherokees take these necessary steps before taking your vehicle to a dealership..........
1. If your vehicle is equipped with a fan clutch, take your hand with the vehicle turned off of course and spin the fan by hand... you should feel resistance, if there is no resistance you will need to replace the fan clutch.
2. If the fan clutch has resistance, turn the air conditioning on... look at the electric fan motors.. both should be spinning if they are not spinning there are two possibilities... there is a relay that is known to fry for the electric motors... verifiy it is working correctly... if it is then you need to replace the electric motor for the fan....
**** another quick and easy way to check the clutch fan is while the engine is running find a focused flashlight of laser pointer and shine it onto the fan blades.. you should see a consistent circles of light if it is spinning properly... if your seeing the laser pointer or flash light hit on blade at a time than you can gurantee that it is the fan clutch.
******* Never take your vehicle to the DEALERSHIP until you have ruled out all simple causes************ The fact that the vehicle is not overheating when your on the highway tells me that the vehicle in fact does not have a HEAD GASKET issue... and the problem at hand is probably an external cooling device... the Fan cluctch or Electric Motor fan...
could also ruened the water pump as think i read that some of the water pumps had plastic impellers
Many thanks
I bought a 2000 Jeep Cherokee Sport with 45k mile (yes, that's right) three days ago. Had them change the timing belt at the dealer before I took it. Have driven it 200 miles. Pulled in the driveway just now and fluid (I think it is coolant) pouring out from under the front.
Of course, dealer now closed and I'm without a car until Monday or Tuesday.
Any ideas would be helpful. I've read on other sites that the water pump should have been changed when they changed the timing belt. Would that cause all the fluids to pour out?
HELP!
Don't know what else to do besides the water pump. But either it works or don't...doesn't it? I don't want to remove the pump only to find nothing's wrong with it. Should I replace the pump or should I donate the truck.
He told me the fan was perfectly fine as well as the relay, (which the jeep dealership would never tell me, and it was the exact same problem for the past 4 yrs with my jeep overheating.) He said the problem was in my electrical motherboard or something like that. He said it the electrical system just wasn't working properly which made it to where my fan wouldn't run right. For 100.00 he connected my fan to the battery (i believe) so that the second my jeep turned on the fan started right away. I've never had an issue with the overheating ONCE since he did that. Now i'm not stating it's the perfect solution for the long run, but if your short on money i'd suggest looking into it as a short time fix. Down here in vegas it will stay hot until mid to late oct so this was the perfect solution for me until i can get the money to fix the main problem. Personal opinion i love my jeep but i think i heard it best from 1 person, with a jeep you either get a real winner or you get a lemon. As i've stated i've had issues with the radiator fan, which i now feel was unjust. All of the window regulators have went out and i've had to replace them all, the power seat on the driver side has had issues with 2 of the buttons, Check ignition light comes on for no reason when it wants to, sometimes it stays on for days, to weeks and then for no reason like putting 5 dollars in gas in it when its 3/4 filled already it goes away all of a sudden lol, it shutters when your stopped at a stop light like it wants to die, and like most jeeps once you get it up to 60 or higher mph it vibrates and hums like crazy. Sorry for long response, i hope this may have helped in some way.... Doug
My 01' JC has 82,000 miles. All winter the heat would not work and it was leaking coolant and the check engine light would go on and off.
Two weeks ago I had a new radiator and thermostat installed and a new belt (something to do with the alternator) installed. When I picked up the car, I drove it around for about 30 minutes and the heat worked fine and the check engine light did not come back on. The next morning, it had leaked reddish fluid and when I started the engine there was a loud screeching noise. I went back to the shop and they suggested I drive it for a few days and see what happens. The leak stopped that day. But, the screeching got worst... now, I hear it every time I start the engine, when I turn on the heat/air, when making turns and even sitting at stop lights! I never had this problem before.
I'm taking it back tomorrow so any suggestions would be helpful because I don't trust the mechanic! :sick:
Thanks!
I really hope someone can help me. I have a long story that I will make short. I was idling in a parking lot and my JGC spiked in temperature. The "check gauges" light came on and I shut the car off and it started pouring out greenish fluid. I had the car towed to the repair shop. They installed a new thermostat and electric fan relays and sent me on my way. As I was transferring all of my gear back into my car in the parking lot of repair shop (car running with air on low), it did it again! Overheated and poured out green stuff. Repair guys came out and were quite embarrassed. They pushed my car back into the bay and got back to work on it.
Next idea was that the radiator cap was bad. Two hours later they called me and said I could come pick up my car. It must have been a bad radiator cap. Well, 3 minutes later they called back and said never mind, the car had overheated again. It didn't get to the point of pouring out the green stuff, but it was close. They told me they would call me the next day and let me know what they found.
So, today I was told that I had blown a head gasket. They say it was caused by my car overheating. How do I know that the blown head gasket was caused by me and not them??? And why wasn't that blown head gasket diagnosed earlier? Am I stuck with this huge bill or should I fight it? I feel like they should have caught it before I overheated the car again! For crying out loud, I was still in their parking lot! One last thing, my radiator was replaced 6 weeks ago and prior to that, 10 months ago! Of course,the second one was covered under a warranty!
Sorry this is so long. I appreciate any feedback or ideas. Thanks!
Dealer said oil cooler built in to main radiator, The oil cooler has burst into the water system, needs replacing and flushing out. £3,500. This is far too much money. The water header tank has a lot of oil in it. Can't see any water in the cooling system. Contacted a radiator company they want £470 for a new radiator, Can any body tell me how long it should take a garage to change the radiator and flush the system out please
Also, I was warned the heater core was cracked but they had disconnected it and would fix it later. Pshaw.
