LISTEN TO THIS IMPORTANT MESSAGE!!!!!!!!!!!!!!!!!!
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...

Not sure if you'll recieve this as it is an older post, but the only info i have for you is not much i'm in the same boat, my 2002 jeep GC laredo does the EXACTTT same thing, there was a recall on the radiator fan because they were basically chit, but once it blows out, your radiator fan relays blows out as well, this has happened to me the past 4 yrs all in june or july, and every year they replace the fan for free since it was an inital recall but it costs me 340 out of pocket for the relay that it blows out, alos i get the exact same message about coolant low and yadda yadda, i have no idea about that, i keep a full bottle of coolant in the jeep along with a jug of water at all times because honestly i have no idea when its going to happen so i take no chances, however if you do get this and have any other further knowledge on this problem let me know would ya, thanks.

Ok So far I still can't figure it out. I changed the relay behind the headlight to find out the one I bought is bad. So I put my old one back in (because the over heating problem is intermittent most of the time until recently)and of course the fan is spinning. But the temp is still going past 210. Tried the laser idea ,and If I point it at the fan it will hold a continuous dot form the laser in a still position(if that makes sense) so what else can I do or need to resolve the over heating problem?

if over heating is intermitant the fan could still be bad and not running up to speed could still turn but not fast enought to cool raddiator

I wish i had more info for you, it took me 3 weeks just to get an appointment at the jeep dealership to have my radiator fan and relay replaced (for the 4th continuous yr in a row) and when i got there i told them to come up with a legit reason why this happens every year but then they told me they needed to keep the jeep for 3 days to do a 4 hr job because they were backed up so i just said screw it and left as the jeep is my only vehicle but i swear if i find out why jeeps are so shitty and constantly have these over heating problems i will post the solution as soon as possible

I had my cooling fan on my 2000 JGC Laredo 3 times and it just went out again. It is fine when I drive, but when sit idle too long it over heats. What gives? got any suggestions for the underlying problem and how to fix t.

Hey there starz8235 I have a solution but i'm not going to guarantee you 100 percent this is the correct answer but i will tell you it's what happened in my situation. I live in las vegas and the for the past 4 yrs my radiator fan has blown out and in return so has my radiator fan relay in my 02 JGC laredo. Every yr i bring it into the same jeep dealership and every yr they replace the fan for free but i pay 340 out of pocket for the relay since the fan itself was originally a recall but not the relay so i get stuck there. I consider myself lucky when it happened this past june. I brought it into the shop but they were so backed up they said they needed to keep the jeep for 3 days and i said screw that, so i went to some rinky dink auto shop and found AN HONEST MECHANIC if you can believe that.
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
