Question about 1990 Jeep Cherokee Limited

1 Answer

When I removed the head on my 1990 Jeep Cherokee the oistons all had a 30 stamped on top. What's up with that? Does that mean this motor is thirty thousanths over? Ill bet it's shot!!! What does anyone else think?

check to see if your hoses are collapsed, bring car to normal operating temp check if hoses collapsed. It sound like a bad head gasket or worse yet a cracked head. look in oil if tan you have water in it bad head or gasket, pull spark plugs see if their wet. when car is cold remove radiator cap let car warm up to normal operating temp if radiator fluid blows up and out of radiator bad head or head gasket. also check sylinder presures another way to check for cracked head.

Cherokee jeep overheating


CHECK YOUR OIL. IF THERE IS WHITE STUFF IN IT THAT WHITE STUFF IS WATER, AND YOU HAVE A BLOWN HEAD GASKET OR A BLOWN INTAKE GASKET. EITHER WAY IT MEANS TEARING DOWN THE TOP HALF OF THE MOTOR. ALSO, IT CAN BE THE WATER PUMP, IF THERE IS NOT ANY WATER IN YOUR OIL. OR YOUR RADIATOR IS CLOGGED.

Adjust fan belt 1990 jeep cheerokee


No diagrams available, but under the power steering pump, over on the right of the motor looking toward the back, there is a bolt 12mm head to the right. It is the tensioner bolt. Loosen the 2 bolts at the very back of the pump, and I think 2 through the pully. It should be easy then.
