Jeep mechanics,help!!

    hello all, well im still looking for a used cherokee for my stepson and found one that has a couple issues, it is overheating, the owner replaced the radiator and all hoses, does this sound like a head gasket, and if so is there anyone out there that would be willing to help me replace it?? i am mechanically inclined, but im no mechanic. i have never done a head gasket and want to do it right. we havnt bought the jeep yet but if we do i want to get this done asap. so if anyone could help with this that would be awesome. its a 2000 cherokee sport and of course it has the 4.0 in it. thanks

    i would check a few things before i pulled the head.has the water pump been checked out?i had one in my shop one time that the fins were gone on the pump,i could take a heater hose off while jeep was running and nothing came out,i blew air through heater core to make sure it was open and it was,or could be a bad thermostat.just something to look at.is there any water in oil,milky?john

    Pull off the water pump and thermostat and flush the engine. Make sure you have the right water pump. The serpentine belt pumps spin opposite the v-belt units.

    Clever quotes added to a person's signature only aim to add more weight to an otherwise feeble point.

    Check the oil for a milky appearance, and get a coolant tester from an auto parts store. Those can check for exhaust mixing with the coolant.


    I battled an overeating problem for a while, turned out to be a bad (new) water pump. Never suspected it because it was only a few months old when the problems started.


    99+ 4.0L engines are prone to cracking the head if they overheat, so keep an eye on the oil and coolant.

    I also had an overheating problem ended up being a loose wire on the electric fan temp. sensor (the fan would not come on when needed . Best way to check is to let the jeep run if the fan does not come on before the dash mounted temp.guage is in the red turn on the a/c the fan should come on .if the fan runs it's the sensor if it doesent its the fan

    haha maybe... stupid phone. Swype is cool but can be annoying.
