Engine Cooling problem
2001 Jeep Cherokee 6 cyl Automatic 147000 miles
Every 500 miles or so, my engine loses a reservoir of radiator fluid. We can't find a leak, no puddles, no overheating. We have put dyes in the fluid and find no leak. Replaced water pump, thermostat. Reseated connections and still cannot find a leak. Test of exhaust have shown no unusual burning. No engine noise such a knocking, no loss of mileage.
Any idea where the fluid is going?
Also, I lose oil pressure when engine is in drive with no acceleration. Cold start up shows noral pressure.
When engine warm, pressure drops to zero with no acceleration.
No loss of fluids, no burning, no exhaust issues, changed pumps and sensors, no change. Any ideas on why pressure drops?
