Coolant Leaking problems of the 2000 Jeep Grand Cherokee

Jeep 2000 Grand Cherokee laredo inline 6cyl 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 have had a slow coolant leak for the last year and cannot figure out why. Also the oil gauge is reading 0 at idle, but goes back to normal when driving. I also have had three different cylinder misfires in the last year. I have taken this vehicle to different repair shops and nobody can tell me where the coolant is going and if these are all related. I have replaced the water pump, oil pressure sensor switch, spark plugs, rail pack, spark plug boots, and thermostat. Vehicle has 120k miles.

2000 Jeep Grand Cherokee laredo 4. 0l inline 6 with cracked cylinder head (between #3 & 4) allowing coolant fluid to leak into engine. Noticed coolant disappearing @90,000 miles. Had pressure test by 2 different dealers. Cracked cylinder head diagnosed by second dealer recently. Problem appears to be a defect in the cylinder head casting #0331. Discovered many other owners with same problem at carsurvey. Org. Under Jeep cherokee reviews. Please order a recall! I could not believe how many people have experienced the same scenario as myself on carsurvey. Org website.

Jeep Grand Cherokee, 2000' losing anti freeze with no obvious source of leak. Now overheating to max temperature even though fully serviced with coolant.

All 2000 grand cl v6 have this problem with no recall. Engine overheats, loses coolant & can't find leak.

My wife and I purchased a 2000 Jeep Grand Cherokee from the dealership. About two years ago the 4. 0 liter 6 cylinder engine started using coolant and causing the coolant light to alarm. The oil pressure would drop to "0" and sound the check gauges alarm. We took the car to the mechanic shop for costly repairs and troubleshooting. They replaced the water pump, couldn't find any leaks, and replaced the oil pump and rear main seal. They checked the bearing clearances and found them within tolerance. The car is still using one to two pints of coolant every three days and the oil continues to drop to "0" after warm-up. We replace the 4 wheel disc brakes and rotors every two years. The hood gas shocks won't hold the hood up and the shocks cost $150 a pair form the dealer and only last one year. We to have electric door locks that screech and don't lock the doors as well as rear light problems that work off and on. The emissions are much higher than normal on our recent smog test. This is an indication that the #3 and 4 cylinder is using the mysterious antifreeze loss. As a retired mechanical engineer I also believe the oil problem to be related. My wife has the Grand Cherokee and I purchased a tj wrangler new in 2000. I'm concerned this vehicle will develop the same problems having the same engine. We have invested over $50 thousand in these two cars. We need your help to help us offset this burden.

My 2000 Jeep Grand Cherokee is having problems like many other people. The low coolant light constantly comes on and I have to add coolant weekly, although there is no visible leak. Mechanics have told me they cannot find the problem until this past week when a mechanic told me the coolant was leaking into my engine and mixing with my oil. The mechanic estimated I will need a completely new engine within a few months since the coolant-oil mixture has been running through my engine for some time now. The mechanic stated that the engine will stop running in the very near future. My rear left brake and tail light goes out when I step on the brakes. I have had several issues with the rotors and finally had the mechanic replace them with a different kind.

I have a 200 Jeep Grand Cherokee laredo and after reading many sites (blogs, complaint sites, etc. ) I see that others are having the exact same problems I am. My Jeep has 101,000 miles on it and it is experiencing coolant leaks and also the crack in the cylinder head between the 3rd and 4th cylinder. Now the y way I see it, is that is soooooo many people are experiencing this problem then there should be a recall on it. It is not fair to the consumers that we are shelling out all of this money for a problem that is in the vehicle design.
