  • Did you get the jeep fixed? if not I'd suggest replacing your water pump have a coolant flush performed, they should bleed the cooling system when they do that. Now there is also a possibility that the electric fan is not kicking on when it reaches about 220 degrees which could either be the fan itself or the coolant temperature sensor. I'd take it to an actual jeep dealership and have them check it out, I'm a Chrysler Jeep dodge technician so I deal with this stuff all the time

  • It turned out to the the whole coolant reservor. Replaced it and everythings fine. Had the thermostat replaced a month ealier already because it was running hot then too. Everythings fine now. I have to fix my MAP Sensor tho, sometimes unplugging it trying to start it and plugging it back in is the only way to get the car started again when its been sitting for more then 4 hours.

  • It is not a radiator problem, it is not a water pump problem, and a flush will not fix it!

    The overheating is cause by poor cooling system design from 88 - 91 XJ's - the one way to fix it permanently is to do a cooling system swap using a 1992 cooling system .... research it for the details.

  • Does the problem with the resevoir apply to newer model xjs that do not have the self contained cooling system. ive had a few problems with mine lately an cant seem to get the problem worked out.

  • i dont know if their is a MAP for gasoline engines but im a diesel mechanic and it stands for manifold absolute pressure.

  • you probably have a blown head gasket or a cracked block, that's why you are getting the bubbles in the reservoir. good luck.

  • i just fixed the pressure problem with a plumbing part, first you have to go to a plumbing supply store, Ferguson is the best, get a 1 and 1/2 in inside compression cap, it has a wing nut on top with a rubber ring in between top and bottom. slide it in the top of your reivoir and tighten wing nut and it compresses the rubber out to make a seal and it wont blow anymore

  • What is a map sensor

  • When you flushed the radiator did you actually take the radiator off, or did you flush the system while running using a T-kit and a water hose. Or did you just use a simple hose the radiator and drain and refill.
