I just fixed a similar problem with the water pump and thermostat. 2000 Jeep Grand Cherokee Limited Edition. Had a similar problem with the lock sound about two years ago. What I want to know is how much the dealer charged everyone for the water pump / thermostat replacement? I think we should send all of these comments to Chrysler and see if we can get a recall issued for the overall coolant system and door locks. If you agree, post on the board. Thanks.

We have experienced numerous heating problems with our 2000 Jeep Grand Cherokee. The radiator has been replaced 3 times, 5 thermostats, 2 water pumps and finally the motor. We are waiting to see what happens now. I definitely believe there are defects somewhere.

I have a 2000 Grand Cherokee Laredo I just bought for 5000. Has 133k on it, and in the 3 days I've had it, it's caught in 2nd and 3rd gear... I'd get to 10 mph, shift, then 15 it would catch, 20 catch, 22 shift.

Low coolant light came on today, looked at the level, it was empty and it was full last night. Coolant leaked over top of the oil pan. Dealer said he's not sure what's wrong.

Brakes are good, engines strong.

Oil light comes on after I run it for a while.

Part time four wheel drive light stayed on while in 2 wheel drive.

My question is anyone got any problems exactly similar? If so what did you do about it, and what parts did you replace, how much did it cost, and does Jeep cover any of these parts on recall or anything if I'm not the original owner?

I have a 2000 Grand Cherokee and mine runs hot a great deal of the time. The temp gets to the red and the check gauges light comes on. After I turn the car off and start it up again it hesitates and misfires. Is this thermostat? water pump? or engine issue?

I am another sucker that owns a 1999 JGC Laredo In-line 6 cyl. 4.0L 4WD. I just replaced the water pump last week. Thankfully, no more leaks have been detected, but when I lift the hood, even if only after a few moments of running, the jeep is still running hot. Hopefully that's normal and isn't an indicator of future problems.

My fuel gauge will not work sometimes too, and it will show empty when I have a full tank. This runs in conjunction with my Jeep not being able to start, or starting after about 10 seconds of turning over. I am guessing something is wrong with the fuel pump? I checked the battery and its showing 12.59 volts, the alternator is at around 13.3 volts, so I don't believe it is an electrical problem.

Also, my brake light keeps coming on intermittently. I just changed the front brakes and rotors- and both boots were torn!- but the light will still come on. Do I need more brake fluid?

The Jeep is a very nice ride, loaded with everything and very convenient for those long trips, but I've had it for 7 months now and its already been a hassle. --I only have 80,000 miles on it too. What more can happen?!

If you coolant is bubbling you may have a bad head gasket or cracked head.

I own a 2000 Jeep Cherokee Limited - I do love the look of this vehical, but have had some issues like the rest of you. My heater does not blow hot air - blows cold. The light " low coolant " came on. I did add it, it was low. Still no hot air. Makes for a cold winter. Also it runs high in park, sounds very loud. The passenger side power door lock does not work. It seems a lot of people I talk to have the same issues with Jeeps of this make and model.

I have to agree with everyone who owns a JGC for 2000. A lot of the problems everyone else is having, I'm in the same boat. I've replaced the thermostat 3 times and the water pump once. And now I've got an issue with the vehicle overheating and the fan not coming on. One of the pins inside the connector melted last night when trying to figure the problem out and the fan does not come on at all. A total recall is a MUST. Now I'm at my wits end on what to do next.

My father owns a 2000 JGC Laredo and last night he was driving on the highway when he blew a frost plug. No warnings nothing to indicate a problem. We did a compression test on it today after having it towed back about 70 miles. On number 1-6 cylinders 30 psi on 6 and 60 psi on cylinder 1. So this is just another frustrating piece to the puzzle. This vehicle has only 58,000 original one owner miles.

I agree with the recall. I have a 2000 JGC Limited and about three months ago I had a problem with coolant loss. Then I was driving it and had a low oil warning light run. I took it in and they pressure tested and found no problems. I then took it into Jeep Naperville and they said they couldn't find the problem with the oil pressure, but suspected the fan or the the fan relay and wanted $700 (but it might not fix the problem). I have read problems about this issue and asked "is this common?" and they said they have never had these problems; then I read this today and am even more mad. I have no idea what is wrong, and don't want to replace everything to find out what is wrong. There should be a recall on JGC for this oil pressure and coolant problem. My car has 79000 miles, and this(problem) is aggravating.

2000 Jeep Grand Cherokee Unexplained Coolant Loss.

4.0L I-6

Most all GC's in 2000/2001 model years develop a crack in the cylinder head between #3 and #4 cylinders. The effected head have a casting number of #0331. First year for the coil packs on the spark plugs. I've replaced with a older style head casting #0630 and had to be creative in making a bracket to support the coil packs. This effected 65% of all GC's with the 4.0 in 2000/2001.

Chrysler is aware of this design flaw as the newer 2002 and up are redesigned completely.

There is no recall that I'm aware of. Good Luck.

2000 Grand Cherokee 4.0L 6-cyl with 144,200 miles, original owner.

Just recently noticed the sweet smell of an antifreeze leak, no sign of a puddle on the garage floor or where I park at work, began searching for the source. I found a stain on the header pipe and realized why there was no puddle, it took a thorough cleaning of the engine to diagnose that the head gasket was blown, although I only see oil oozing near the #3-4 cylinder on the passanger side I’m sure the antifreeze is doing the same and landing on the header pipe where it cooks off. I was just about to order parts and have my head machined when I read this latest post. Since my symptoms are so close to this story I have no confidence in attempting rework of the existing head, I'm sure I could have it tested for a crack, likely FPI, but why spend the money. Are there any options other than an OEM head? If this is chronic to some degree factory spare parts are likely to be no better in time.
