Only problem with some stealerships is that they will pass this vehicle off
to the "new guy", who many times is not all that experienced with the 4.0 ,
yes he knows how to change the spark plugs, change the oil and stuff like
that. You need to talk to your local service manager and see if the stealer
has a dedicated "jeep guy". Stealership I used to go to had one of the best
around, he would also lend out his jeep if the situation dictated so he
could drive the customers jeep and pin point the problem. Too bad the new
service manager didn't realize what he had before he let the gent go.

Re: Cherokee Overheating - Replace Engine ?
 

Doug,

Thanks so much for the response. This is one of the frustrating
moments in life where wish you knew more about _____<insert topic
here>__.

> 1) crack in line to overflow bottle
I'll take a look this weekend. Although this may be a symptm more
than "the problem" because the car still overheats when there is
plenty of fluid.
I'll check the radiator when the car is cold ...wanna' keep the skin
i've got.


> 2) leak in the return hose/supply hose/radiator
The radiator , hosess and water pump were just replace. They could be
leaking, i'll take a close look. Other than just before the radiator
was replaced i haven't seen what you described.

> 3) leak in the heater core
well i'm not sure if you meant the cabin of the car or the engine
compartment, but can't say i've experienced this in either place.

> 4) cracked head gasket
The mechanic said he check the head gasket and didn't find a crack.
I'm taking everything he said skeptically, so i will look for white
foam in the oil. But, the car defenitely does not pour white smoke.
Other than the stupid thing overheating, it looks, sounds and runs
pretty well.

> 5) leaky water pump
New water pump, but i'll try to find this weep hole and make sure its
dry.


> 6) buggered up radiator causing overheat.
Got suckered into a new radiator, so i hope no sludge was added to the
new radiator.


I'm hearing that this isn't a "just throw the car away" type of
problem. I'm going to go to a dealer near me (northern jersy) and pay
for diagnostics. And hope they can find something.

Thanks again for the help.
