Takata recall I own a 2000 Jeep Cherokee inline 6 and since I got it it has had a lot of problems with the head and blowing the gaskets I called the dealership to see if there was any recalls and there wasn't any. The lady that was working asked me what was going on and I told her and she said that my year Jeep should've had a recall for it because a lot of people have had the same problem. This is really the only problem I have with my Jeep and everyone I talk to that has a Jeep like mine and the same year have the same problem. This will be the second head gaskets in 4 years I will be putting on new head gaskets. I can't afford a new head for it and I've been told that the heads were bad on my year of Jeep. It also came with dexron antifreeze that after a while gooks up in the radiator and looks like mud.
Driving on the highway at 60mph and Jeep starts to overheat. Had mechanic check it out couldn't find a problem. Replaced radiator, thermostat, coolant system flush, and new antifreeze replaced. That seemed to fix the problem but then I would have to keep refilling antifreeze but it was not leaking any this went on for about a year then I noticed brown gunk in the overflow container and had a mechanic check it out and he said that was due to the antifreeze mixing with oil most likely caused by a cracked cylinder head. After some research I found it was extremely common that the 2000 Jeep Cherokees would crack their cylinder heads between the 3 and 4 heads. Very annoying to diagnose and fix.
Bought vehicle new and performed regular maintenance. Had to replace brake rotors at 62,000. At 78,000 miles engine overheated; verified fan, radiator, and water pump in working order and replaced thermostat and temperature sensor. Engine continued to overheat with unexplained coolant loss. No leakage and clean oil. Replaced head gasket anyway and noticed no cracks in head. Still runs hot and loses coolant somehow. At 80,000 miles engine developed miss after replacing coil and checking fuel and firing systems removed head again and pulled lifters. Bottom of one lifter was ground off resulting in some wear of cam lobe. Replaced lifters and valve springs. Fixed engine miss. At 82,000 miles oil gauge showed 80 pounds of oil pressure until engine totally warm then dropped to 40 lbs. Also showed 40 lbs when keyed moved to on position with engine not running. Replaced oil pressure sending unit. Now engine runs 40-45 lbs when cold and drops to 10 lbs when running after totally warm. When stopping at lights after driving with warm engine, oil pressure drops to 0 and check gauges light comes on. Purchased a high volume oil pump and will see if this corrects that problem. This is totally unacceptable for a vehicle with 83,000 miles that was purchased new and well maintained. Furthermore when checking with other owners these problems and more seem to be common for this year/model.
I have had engine overheating problems on my 2000 Jeep Cherokee, door actuators going bad, and also oil pressure gauge going to zero, and also loosing anti freeze. I have replaced the head once for the coolant loss and didn't do any good, I've had the thermostat switched for overheating and also the radiator fan , no help.
Tl- caller owns a 2000 Jeep Cherokee. Current mileage is 71000. Failure mileage is 68000. While driving 40mph caller noticed temeperature gauge and pulled over and tried to correct the problem by adding coolant to radiator. Vehicle cooled off and he put a new head on the engine a week later. The vehicle is still running hot. Ktf the consumer stated the exhaust header is too close to the engine block oil pan causing overheating. Updated 06/08/07.
'check gauges' light comes on multiple times, temperature gauge to redline for a few minutes, then back to normal. Brought in to be checked/fixed 5 times, 'no leak', 'no problem detected', 'radiator hose loose', 'added coolant' until this last time: 'cracked head'; also oil gauge recently shows no pressure with great frequency, as with temperature gauge. I had been adding coolant every few weeks. I believe this problem could seize the engine while vehicle is in motion.
