Sounds like a pulley is going, just changed the water pump but that wasn't it. Kinda sounds like it is coming from the mechanical fan but not really sure. Just wondering if anyone had any ideas. Also I noticed my serpentine belt is fairly loose, how do I tighten it?? This is for a 1990 XJ w/ 4.0.

Strange noise from front of engine

The adjustment involves loosening four bolts retaining the power steering pump and adjusting a turn-screw under the pump to tighten. It may require unplugging the CCV or vacuum tubes here or there to obtain the room to do it. Refer to a Haynes, Chilton or FSM for the details.
I too have a faint mystery noise I attributed to the water pump and replaced it and the fan clutch to no avail. It only occurs after revving in neutral on the decel. It is only audible with the hood up. I'll dig a little later to see if I can find it.

You might want to check out your power steering pump. I've got a 98 XJ and just replaced mine after the little sound turned into an all out big sound.
All's well now, about $320 later!!!!
