1997 Cherokee Sport Major Problems - Need Help!
I have a 1997 Cherokee Sport 6cy. 4liter. I bought it used and it ran fine, dealer said they had just replaced water pump. One week after I had it, it started to overheat. Replaced thermostat and ran fine for a few days, then overheated again. Took to mechanic said head gasket was blown. Took the manifold off and had it milled. Replaced the head gasket and all was good for about a week and started overheating again! I've replaced the spark plugs, spark plug wires, changed the oil (did this when I replaced the head gasket), flushed radiator, and changed the water pump. The problem now is that it starts but when I drive, it stalls out and I get a check gauges light on. Then I have trouble starting it again and there is a tapping noise. I'm about ready to pull my hair out. Anyone have any suggestions? I did do a little research on the water pump and was told it had a reverse rotation. When I pulled the old water pump off there was not an "R" stamped on it could a bad water pump have caused all this trouble? Thanks!
