Question about 2000 Jeep Grand Cherokee

My jeep is over heating. Already replaced the

My jeep is over heating. Already replaced the thermostat. Didn't fix the problem. Someone is telling me it is a bad serpentine belt. The belt looks fine to me. They said that it does not matter what it looks like it is probably still bad. Could this be true? Guess I should state that it is not fully overheating. At times it gets to about 240 under stress (Excessive acceleration or long hills or running the A/C) and then cools down again.

From the last portion about your drving conditions, it is normal gets hot, especially going up hills with the A/C on. Sometime the water pumps start to weaken but also a clogged radiator, slowing the flow of cooled coolant through your motor or even through the radiator....check to be sure you have the proper level of coolant also.

Replaced radiator and tstat still over heating, water pump a little over a month old

my used 4 cyl jeep radiator would only drain 1/2 of the fluid. jumped up and down on bumper and this dislodged the sludge in radiator and/or engine. flushed twice, then now notice low temp reading on gauge (out of specs) due to a low temp thermostat that someone installed due to previous over heating (sludge). Replace with factor spec thermostat and everything is fine.

My 1996 jeep grand cherokee limited has no heat, the blower works, and the air works great. We put a new thermostat on. but it didn't help. any ideas?

does it eventually heat up (long trips, etc) or not at all. If not at all, check the heater core, it may not be getting any fluid. If it eventually gets heat, you may have put the t-stat in backwards, or its stuck in the "open" position

My 1998 Jeep Grand Cherokee is over heating and I have already replaced the water pump. Someone told me it might be the heat censor. Could this be right and if so how much is it going to cost me.

Be careful, with engine at normal oper. temp. feel both upper and lower radiator hoses, they should both feel the same, warm to hot, if not the same temp. replace the thermostat.Heat sensor either work's or not, if it reads hot, engine is hot, or will not work at all.

Overheating after driving few minutes doesnt while idleing all typical problems have been checked

What you said tells me nothing. What one person considers typical, someone else does not. It sounds like you have a partially obstructed radiator (external or internal), causing heat transfer to be marginal while driving but sufficient to work at idle. This can be determined by using a heat sensing "gun" but sometimes that won't work if the obstructions aren't grouped together. Flushing sometimes helps but often the "over the counter" flush chems are not strong enough and simply clean up the passageways that are already flowing and go around the ones that are not.
A partially opening thermostat can do this as well. You said you checked "typical" problems but did you replace that?
Additionally, have you had the cooling system checked for hydrocarbons? A developing head gasket leak can give similar problems
if it hasn't yet entirely failed.
Based on the fact that it happens while under way, I'd consider having the radiator professionally flushed or change it altogether. Once an engine overheats the thermostat becomes unreliable so regardless, replace that as well. You should check fan operation but unless you are in traffic, you can actually run without a fan at highway speeds and not overheat.

95 Jeep Wrangler YJ...No heat, temp at about

It should be 200 degrees. If your running cold the only thing that regulates temp is the thermostat. If it is indeed 150 degrees thats why you have no heat.

If you replaced the water pump and the radiator for this condition then it was a waste of money. If you had a water pump or radiator problem it would overheat.

The fact that your blowing cold air tells me the that you really are 150 degrees or the heater core is plugged.

1997 Jeep Cherokee suddenly runs hot and dies.

The first thing you need to do is find out what that check engine light is, you local auto parts store will probably pull the codes for you for free. Other than that, maybe the head gasket is blown?
