I bought a 2000 cherokee in June 2005, I replaced the water pump in Nov 2005,it was leaking anti freeze bad. Everything was fine until yesterday (Feb 26 2006) with the coolant low light came on. Is this normal? live in New York and it has been cold last couple days.

To the previous poster with the low coolant issue: I would suspect that when you replaced your water pump, the coolant system was not fully re-filled. I know you fully believe that you filled it, but you didn't, because you filled up the radiator while leaving the block empty, not waiting for the thermostat to open and draw the coolant into the block. Your warning light finally came on after driving the car for a couple of months with the cooling system only half full. Take off the radiator cap and check the fluid level. Fill the radiator to the brim. Then let the engine run until it warms up and physically observe the level of the radiator with the cap off. Don't put the cap back on until the temperature gauge moves off cold, or fluid starts spilling over the radiator cap neck. After you put the cap back on, then fill the overflow bottle to the proper level. The same thing happened to me when my car went to the body shop. They replaced a freeze plug, and the mechanic's flunky was given the responsibility to refill the cooling system. He would have sworn on the Almighty Throne that he filled it, he believed it, but driving it home the car overheated with the temp gauge buried, and I knew the stupid SOB had only filled up the radiator, without bothering to wait for the thermostat to open. They all do it, even though they're the experts and know it all...

I can't believe what I am reading. At 69,000 miles I had to replace the water pump and fan clutch in my 2000 GCL 4.7 V8. It is still overheating. I do not know what to do. I have heard that the fan relay could be bad, but the fan is kicking on. My next guess is that the radiator in obstructed. If anyone has any suggestions please let me know. I may go ahead and replace the thermostat just in case. This is a nightmare.

Well add another ditto to this forum. I have a 2000 JGC. I bought it used and I had the dealer replace the clutch fan and water pump when the low coolant indicator came on. After a month or so it returned. It seems that I am intermittently losing coolant. Last month I started getting the check gauges indication at start-up. (Low or no oil pressure) Combined with having to replace two of the door locks (grinding sound) I know there is definitely something wrong with this model year. Why else would I find other owners experiencing the same issues?

I have been having issues with my 2000 Grand Jeep Cherokee. Just recently, the vehicle kept cutting off while driving, I had the crank position sensor changed, I had the oil pressure switch changed. The tie rods had to be replaced they broke one day on the way to work and now there is another issue with the oil pressure.

The back brake lights stopped working properly the third day after purchase, three traffic stops by the the New York Police Department for faulty equipment and three years later.

I love this vehicle and it handles very well on the road, but I think I made a bad choice with the 2000 Jeep Grand Cherokee.

Wow sounds like some people got some bad Grand Cherokee's. one of my coachs have an old 97 Grand Cherokee with the 4.0L (same drivetrain as in the newer Grand Cherokee's) and it has over 170,000 and not one problem with it. and they didn't change the motor design at all from 87-04. anyways. for the coolant problem, are you sure you don't have a hole in the radiator? our Neon got just a small hole and the car kept over heating for the longest time, with no sign of leakage, until we parked it on a hill and came back like 5 min. later and there was nothing, but coolant all over the ground. I put some of that stop radiator leak thing and so far its worked great.

I own a 1997 JGC 5.7l V8. Got it last year 20Sept06. 30days later coolant light came on and we found coolant mixed with the oil. Fixed the everything, I mean everything. Still I am losing oil pressure and heat build gauge seems to be working over time. I always wanted a jeep finally got one... and seeing how many people have the same issue as me... I will never buy one again.

I have a 2000 Jeep Grand Cherokee and I'm having the same coolant issue I have changed the thermostat, fan motor, water pump and the coolant sensor and it's still running hot the only other thing we can think of is the coolant fan relay. Any suggestions for this?

I purchased a 2000 Jeep Grand Cherokee Laredo, it came with all the bells and whistles, 131,000 miles. Looks and runs great and got it for a good price. I love this truck. The only major problem I'm having is that the Low Coolant Level warning indicator keeps coming on about every 2 weeks or so, and won't stop beeping until I top off the reservoir.. I've gone through almost 10 jugs of coolant / antifreeze in the almost 3 months that I own it.. I keep 2 jugs on board now at all times. This is really starting to annoy me. I met a guy with the same truck and same problem. What's going on? There aren't any visible signs of leakage anywhere so where is all this coolant going??

I have a 2000 Jeep Grand Cherokee also, and am having the same problems that most of the other people have stated.. It keeps over heating when it gets hot outside. Every four or five days I need to put coolant in the car.. There is no leak, get a new thermostat, new water pump, I don't know what else to do.. Plus the locks make this funny noise and I have to lock them manually. Also the rear tail lights don't work when my lights are on.. But during the day they work fine.. I will never buy a jeep again. So many little problems that the manufacturer should deal with, not me.
