    We have a 2000 Jeep Cherokee. Put a 3" lift and 31X10.50x15R tires on it. Also just had the engine recently rebuilt by a trusted garage. Our problem is that it continues to overheat. The fans appear to be working properly. What can we do to stop the overheating?

    I also had a 1996 Cherokee with no modifications that would run hot while towing a small load.

Noise coming from radiator cooling fan in 2000 jeep grand cherokee 4.0


Typically you need to replace the fan clutch. (This is presuming that you are not overheating and not near too hot. Under hot condition, your issue is normal.) The clutch can fail in the locked position.

Overheating issues for a 2001 grand jeep cherokke


If it was overheating at freeway speed then it is a clogged radiator. Another cause of overheating is a timing that is retarded. These can be caused by worn timing components etc, although a possiblity it is highly unlikely on your car.

Truck is running hot.


Dunno had a 2000 just like yours still runs like a tank steady dependable sturdy know several other folks who have the 4.0 and never any problems. your motor is bulliproof, sounds like you just had bad luck and got a weak one. check the computer see if it needs resetting, is it thowing any codes? a shop should b able to tell you. it should run at 210 and not move. i drove mine in -5 below zero to 105 and it was allways the same so maybe you just got a bad one

i was having that problem with my 4.7 2000 laredo. had no idea what it was. after about a week and a half of my jeep sounding like a diesel i was going 75 on the freeway and my engine started to rattle and shake violently and then shut off and left me stuck on the freeway. took it to a shop and they told me i had bent a valve because my timing chain had jumped. motor is now beyond repairable. new motor is going to run me $2300 plus $1700 in labor (assuming nothing else needs replacing) highly recommend taking it into a shop asap
