Bought my 2000 Grand Cherokee Laredo with the inline 6 cylinder, new in 2000.

Have replaced water pump, approx 75,000 miles, radiator and hoses, approx 85,000 miles.

Valve cover, and oil pan gaskets, 100,000 miles.

Fan replaced under warranty. Regularly serviced at dealer.

Now at 128,000 miles, and running strong. (Knock on wood).

Power door locks replaced, approx. 4. Expensive.

One rear axle bearing. 2 brake jobs.

I have a 2000 GCL six cylinder - heater stopped heating, air blows fine.

Replaced the thermostat; it now seems to be spraying a fine mist from T-stat housing.

Have had coolant loss issue for some time, but this has me perplexed. Have tightened and retightened the bolts; can't seem to get the leak stopped; any suggestions?

Man, I wish I would have seen this site one month ago. I bought a beautiful 2000 Grand Cherokee Laredo (143,000) and within two weeks the engine had the "click" noise of death! I loved driving the thing. Now I'm looking for a new engine... trying to make some lemonade!

I am interested in the several comments where the electric fan was abandoned and a clutch fan was installed. I notice the water pump shaft is threaded.

What are the details in installing the mechanical fan and clutch?...and what all parts are required...Source?

In Australia the 2000 GC has a Mechanical Clutch Fan (Vicious Coupling) attached to the water pump by the thread on the pump shaft.

This is probably because of the higher ambient temperatures here.

You could maybe source the Aussie part numbers and buy local or ship it from Australia.

Mine only has a cracked head, it doesn't run hot.

I own a 2000 Grand Cherokee Laredo 4.0 and after reading these posts I'm wondering what to do with mine. I bought it new but have had no issues what so ever with it. Now at 73,000 miles the only money I put into it was what all cars need a battery, brake pads, tires and oil changes. I feel like I got the truck built for the president of the company. I wonder now if my luck will hold out or will the bottom drop out soon. I had no idea any of these problems were going on. For me it has been a dream truck, nice looking and drives as comfortable as my Buick with air suspension, and best of all it gets 18 mpg city, which is above what the sticker stated.

I also have a 2000 JGC Limited.

We loved all the bells and whistles, and the look of the truck, and have owned other Jeeps in the past and loved them.

This one the door lock does not work (you have to lock it manually), the heater stopped blowing hot air (the dealer blows plenty), and we replaced the radiator 15 months ago, and we need to replace it again.

It is our money pit. I will never own or recommend a Jeep in the future. This needs to be recalled.

Have a 2000 Jeep Cherokee Sport 4.0. It has low oil pressure @ idle when warm. It was also consuming coolant, but I replaced the head gasket yesterday so I'm hoping that part is fixed. Anyways, this mystery oil crap is a bunch of bull and a ton of people have it. I read in one place on the Internet about a tube going to the sender being cracked. The only problem is to me it looks like the sending unit attaches right next to the oil filter, sans any tube. If anyone thinks they can help, or is putting together a list for a suit, let me know.

I have a 2000 Jeep Grand Cherokee 4.0 liter. 3 of the 4 door locks are bad. What happens if you’re in a wreck and your children can't get out? The brake lights have gone out several times. The headlights are dangerous since they are not clear any longer and very dim even with new Sylvania head lamps.

I had the low oil pressure thing going on since it was just out of warranty. Replacing the oil pump solved that.

We have around 125,000 miles on our jeep. It has been losing coolant since 50,000 miles.

Now it’s overheating. The mechanic says there was water in the oil and he suspects a cracked cylinder head. The estimated repair cost is 2,000.00.

Does anyone know how to replace the head? Why is it so expensive? Would I be better off finding the part myself and getting a “back yard mechanic” to replace it?

Auto-Zone has a “Blue Devil” product that is Guaranteed to fix cracked heads. Has anyone tried this stuff? It’s $65.00.

I also have the cooling / oil pressure / cylinder head issues as many have written about (2001 Jeep GC). I just posted a complaint on www.nhtsa.gov and I hope everyone on this post does the same. I am also writing Chrysler, someone earlier posted the address: Chrysler LLC, P.O. Box 21-8007, Auburn Hills, MI 48321-8007.

My husband and I purchased a 2000 JGC six months ago. When we purchased it, it only had 72,000 miles. We have had the basic problems so far.

We have had problems with the back light going in and out, and we have had problems with our left signal light only working when it was hot outside, or when we had been running the truck all day.

Now our problem consists of our transmission. We have stalling problems and the truck wouldn't go over 20mph. We couldn't make back to the dealer that we purchased the truck from, so we could only make it up the street from our home to a transmission place. He said it was something inside of the transmission that needed to be fixed. That was only going to cost 395.00, so we said okay that would be fine. He opens the transmission and it falls apart, and we were told that a pin fell out and caused everything else to fall out. Now our cost to get our truck fixed will be 2,000.00.

I have emailed Jeep.com and no one has called me back. I talked to the general manager of where we got the truck, and he said there is nothing that they can do. I also went to Jeep Grand Cherokee Laredo Utility Recalls and saw other problems that might go wrong with the truck. My husband and I are truly looking for a way to get these situations fixed we need a recall. All these problems shouldn't not be going on in these trucks. If you have any information, please feel free to email me at mrs.swinton1@yahoo.com

Hi all, I own a 2001 JGC 4.0L.

My first problem common with all of these was the overheating. My cooling fan would not kick on at all. After reading up on it, I found out that it was smart to change the fan relay. The relay cost me $50.00. If I would have taken it to a dealership I could have been paying over 200 dollars for this repair.

To replace this relay, you need to take off the passenger side headlight, and near the middle of the plastic directly beneath it, cut out a square big enough to see the relay and unscrew the bolts. After replacing the relay, my fan now works perfectly.

Now I also am having an oil pressure problem. When I first start it my oil pressure will stay above 40psi or around 40 psi. Once my engine warms up, my oil pressure drops down to about 20psi. After pressing the gas again it quickly goes up to around 40psi. I read that it is normal for a 4L jeep to have oil pressure as low as 13psi at idle. And 40psi driving. I think I might try and test the pressure with a mechanical pressure gauge, after that I may or may not replace the oil pressure sender depending on my mech gauge results.

If anyone figures out the oil pressure problem please give me a shout at dsmizzith@gmail.com Thanks.
