2000 Jeep Cherokee 6 cyl Four Wheel Drive Automatic 70k miles
Looses coolant. Have to refill the resevoir every 1-2 weeks. Replaced the water pump and also did a pressure test. Oil does not appear to have water in it.
At start up, oil pressure reads 40+ at highway speeds/rpms, then gradually drops to 20-30 psi (dash gauge) at same rpms as engine warms. After warm up, at idle, the check gauges light comes on and the oil pressure gauge can be observed to fluctuate around 10 and then suddenly fall to zero.
have the same problem?
