Could this be a water pump? How big a job is this with a Chilton's manual/shop repair? Any suggestion welcome. I bought this rig new and can't part with her. Love my '91 and '02 Troopers, yet still old and in the way. Stock can be fun too!

Is there a seep hole that I can visualize to see if fluid is getting around the bearings? Love my '91 and '02 Troopers, yet still old and in the way. Stock can be fun too!

Basically you need to get the fan shroud out of the way, you may need to remove the power steering pump, depending on the number of angles that you elbows can achieve and the same for the A/C compressor. Once you can get to it, unbolt the water pump. Clean the gasket surface, and reinstall the new pump. There is a weep hole, but you may need a double jointed eyeball to see it.

It ended up being my fan clutch. I even changed the thermostate and it helped for a day but then it started again. When i changed my fan clutch it fixed it and now goes the a little more than quarter way and stays there for the whole time. 88 Trooper. 1.5 inch lift.
