2000 Jeep Grand Cherokee Laredo In-line 6 cyl. 4.0L from North America - Comments

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.

I have a 2000 Grand C. Jeep 6 cyl. The car has 125,000 miles. I recently experienced low coolant and oil pressure problems. I had the water pump replaced, the oil sensor switch replaced, and the oil pump replaced. The repairs were done individually in that order. I am still experiencing low coolant although the car does not seem to overheat. I recently had a pressure test and there were no leaks. When the car is started in the morning I have the proper oil pressure. As soon as the car warms up the oil pressure fluctuates and eventually activates the alert indicator (bell sound). The engine sounds fine and there are no performance problems. I brought the car back to the service station that did the repairs. The mechanic suggested that I use a heavier oil for the pressure problem. I will let you know the results. This may be the last attempt before an engine overhaul. Jeep should have a recall for these problems.

I am serious about the recall on the 2000 Jeep Grand Cherokee. Right now, I am out of a car because the thing started overheating. If anyone wants to call Chrysler because of all the problems with this car please contact me.

Thanks.

Oh No... what did I just get myself into. I just bought a Jeep Grand Cherokee (November 9th). This is the first car I have ever had to buy. I don't have a lot of money and I also financed it. I'm REALLY hope mine will be a good one.

Don't count on it getting any better. I have a 2000 GCG and have the same problems with overheating. Had a new water pump, fan motor, radiator and now a new radiator hose being installed. I have spent more on repairs on this overheating problem than anyone can imagine. Something needs to be done and it is still overheating. All these repairs in the last year. Has 120,000 miles. All problems relate to overheating. Now having problems with the transmission. If anyone out there has any suggestions PLEASE I cannot afford more repairs.

I bought a 2000 jgc I worked it off. 200,000 miles

The guy I got it from said that it needed

a value replaced. I got it home and it ran, but not good.

I finally took off the head. I was mad to see that number 5

piston had a hole in it that I could stick a screw driver in.

Right by the spark plug end. The lower part of the engine didn't sound good. I was thinking about putting a used one in

but hearing all this I think a screwed up.

Looking for a good motor thomas_cole78@yahoo.com.

Hello All. My mom has a 2000 GGC with the I6 motor. When she would stop the oil gage would drop to 0 and the check gages light would come on, but when you accelerated, it would go back up to 40.

I took off the oil pressure switch and found it had oil on the actual plug, so I knew it was bad. I replaced it (50 bucks) and the gage now reads 42 all the time.

Thank goodness that's all it was... I hope this helps someone.

I too have a 2000 GC and have all of the symptoms. Door acuator, overheating, transmissions slippage (or not wanting to shift at times), tail lights, cooling, heating (or lack of), and I have to stop listing them because I just get mad thinking about it. I have filed a complaint with the National Highway Transportation Safety Association (NHTSA). Maybe if enough complaints get filed, they will look into it, I doubt it, but you never know.

I have a Jeep Grand Cherokee 2000. It has 106,000 miles. It has had a lot of problems over the years, but I had an excellent warranty so I lived with it. That warranty is now expired. My jeep has had problems with the tail lights and have had to replace both assembly units completely. I had both door electronic door locks replaced, as well as a problem with the key assembly on the steering wheel, which locked and I was unable to start the car at all. That time I had to be towed in on a wrecker because the steering wheel was locked, and therefore the wheels were too. I have had at least four major oil leaks repaired, and most recently, I had the fuel pump replaced due to a cool leak. That was three months ago, and the coolant light has just come on again. As a side note, the driver's side seat electronics stopped working, and that had to be replaced in order to adjust the seat. I promised myself I would sell the car before the warranty expired, but I didn't, and I very much regret it.

I have a 2000 Grand Cherokee and have had the motor go out, and had to replace my radiator. I'm also am now having problems with the transmission.

I bought my Jeep with 137,000 miles on it and have had one problem after another.

The 2000 Jeeps should be recalled. I agree.

Greetings, I too have a 2001 Grand Cherokee with 79,000 miles that’s losing antifreeze not visibly causing the “low coolant” lamp and after warming the oil pressure drops causing “check engine” lamp to appear. I’ve never seen any abnormal gauge readings, but I have noticed for sometime steam coming out of my hood once the engine warmed. I mentioned this to my local (neighbor) repair guy, he had no answer.

Two trusted local mechanics both said “sell it”, sell your problem to someone else, I said that’s not me. They both said “they did it to you”.

After reading all these similar comments I too believe these engines are flawed, but getting anything out of Chrysler would be shocking.

I own a 2000 jgc with 140,000 miles, with all of the same problems you all have spoken of (door locks, key won't turn, radiator, and the mother of all the tranny). This one in particular worries me is the tranny. Almost 3 years ago I had it rebuilt and it was fine for 6 months ($700). Then it started again and that was two years ago. It stops when the engine heats up, and my mechanic said the Torque converter leaks pressure. So when the engine is warm it shifts fine. I want to fix it, but I'm not sure its worth the money.

I have a 2000 jeep grand cherokee and I have 173,000 miles. I have had to replace the water twice. I have had the fan problem, the fan now runs constantly, it is suppose to run intermittenly. I cannot find the problem. The check engine light is on constantly, despite having a tech. check it for me.

I too have a 2000 Grand Cherokee Laredo 99,969 miles. The low coolant issue is where I'm at now, after already fixing most all of the other issues people have had on this site. I have to fill the overflow bottle every other day and I never see where it's leaking from. The car does not overheat either.

The mechanic said I need a new water pump and fan clutch. He showed me where it was loose and he could rock it back and forth. Said it would most likely get sheared off any day now and leave me stranded.

That sounds reasonable to me. Did anyone else have these repairs and did it fix the problem?
