Please Diagnose My Jeep
Please Diagnose My Jeep
I have a 1994 Jeep Grand Cherokee Laredo.
Start the engine, sounds fine. Then, after a few moments, there's a
terrible rattle. No performance problems, just bothersome. You can
hear the sound fairly well on the video:

What's causing this knocking/rattling noise? Any ideas? How much will
it cost to repair?
Thanks!

Looks to be in time with the fan rotation (hitting shroud?) - water pump
bearing or fan clutch. Don't let it come apart and drill into your
radiator.
If not that, check belt tensioner pulleys.

I had a bad sound like that with my 1993 Voyager. It turned out to be
the water pump. It sounded like a high pitched rattle sound, as
opposed to a worn bearing sound.
I would also suggest checking the fan clutch as Bill suggested.
Perhaps you could remove the belt and run it for a few seconds to see
if the noise goes away. Any one have any other suggestions to diagnose
a worn fan clutch?
