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

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?

Thanks.

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 was wondering if the owners of the 4.0 Jeeps that had oil pressure problems, did the new high volume oil pump fix the problem? I have a 2000 Wrangler and I noticed it didn't have the oil pressure I would like to see, but I have owned several before that were bullet proof, so I said what the heck and bought it anyway. Now I have no pressure at idle after it warms up and only 15 at 2500 rpms. Someone please help.

WOW!!! I have read every post on this page and let me tell you it doesn't take a rocket scientist to tell you that JEEP has a major defect in its cylinder head. I too just took my 2000 Jeep Cherokee ltd. (108,000 miles) into the shop because of overheating, and no big surprise I have a cracked head. I am all for filing for a class action or trying to get a recall! Has anyone started organizing one yet? Let me know.

PS: People with this problem... If you replace the cylinder head and spend all that money did it work? or is going down that road just throwing money into a bottomless pit? you can reach me at hannemanstunts@gmail.com.

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.nhsta.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 only 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 were 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.

I have a 2000 JGC with the 4.0 I6. I've read a lot of these comments on how this vehicle is so unreliable etc. The 4.0 I6 is one of the most reliable engines ever built, and is the best engine Jeep has ever had. I bought my Jeep with 72,000 Miles in 06 and I now have 120,000. The only problem I have had with it is the waterpump which went out at 100,000. I replaced it myself for only about 50-60 dollars. Recently I have found my car overheating in traffic, most likely due to a faulty fan relay. (50.00 at AutoZone). Good luck with the Jeeps everyone.

I also have a 1988 Cherokee with a I6 too.. Haven't had a problem other than a little oil leakage.. Nothing too serious. 200k miles still going strong.

I have a 2000 Grand Cherkee Lardo with an I6 with a cracked head. Jeep really needs to stop their crap and help us. Thank god I can do all the work on it my self. I'm on my 3rd transmission. 4th set of front rotors, broken driver seat what next. 173,000 miles.

OK, here is the kicker!!! my 1987 XJ Jeep Cherokee 4x4 with 365,000 miles and the only thing I ever did was timing chains water pumps and 1 radiator. And I drove it in the mud every weekend. Oh yeah 1 start.

I own a 2000 JGC 4.0, 6 cyl. 2wd. Bought it in '07 with about 120k miles. after a few months I noticed it was losing coolant somewhere, never figured out where, but I had to add coolant every 2 weeks or so, slow leak. Some of that black pepper looking stop leak stuff took care of that.

Then I started noticing the low oil pressure thing, got worst over time to where it would drop to 20 at stop lights. One day while accelerating onto a highway the engine went clack, clack, clack.. I was able to drove it to a shop where it finally threw a piston and died. Replaced the engine with one from the junk yard.

That was around 30k miles ago since then I replaced the battery, starter and the steering damper. Was also having problems overheating which led to a leak in the radiator. Problem due to a faulty electric radiator cooling fan. Then checked the clutch fan and that was shot too.

My hazard and signal light relay went bad and took 2 days and 2 shops to locate where it is since it is buried in the drivers side under dashboard. Only dealer sells this stupid relay for about $50.

Okay as of today my problems are a small leak in the power steering hose. Tie rod ends need replacing. And there is a constant whirring noise coming from the front end. Oh and my drivers seat is broken.

But I still love my Jeep; I have had worse.

I have a 2000 Grand Cherokee 4.0/6 cylinder with 125,000 miles on it. Right now the car overheats when in traffic or when I'm idling for a only a few minutes. The other problem is the passenger side door doesn't lock/unlock, and makes a real loud sound when attempting to open/shut. Other than that it's been a real good car for the 50,000 miles I've put on it. Any suggestions on how to fix these problems? Do I need to replace the door actuator? Do I need to replace the thermostat or is it a relay problem? Any help is appreciated.
