Saturday night there was a very audible noise randomly coming from the engine bay of my wifes 97 4.0 GC . I grab a flashlight pop the hood and watch and listen. Sounded like a pulley but which one. Kept watching for a bit then I finally seen it. The pulley on the water pump would kick to the side a bit make the tapping noise then straighten back up. So I think to myself...great...there goes some of my Sunday.
So I get up Sunday and head outside to see if anythings loose...just my luck...of course not. Dig a little bit further by removing the fan and shroud then belt and finally the pulley comes off and there it is. The bearing on the water pump is going. You could wiggle it freely and then see where the pulley had been touching the housing and making the lovely noise.
So I continue to remove the PS pump bracket then on to the water pump but no sign of coolant leaking...oh yeah...I drained the coolant before removing the pump...then once the pump is off...hey!!! theres a little coolant residue from the weep hole. So evidently it was starting to fail but not enough to show signs of coolant loss.
Put it all back together so the wife can have her Jeep for work Monday. Just wanted to share how I lost my one and only off day to yet another Jeep repair...God I love Jeeps...some times I wonder why I couldnt have been a Ford or Chevy kind of guy.
