Thanks for checking out my thread. Looking for information on the rattling noise on my 998. Its an original 89 6.2 truck. Been driving it a year and a rattling noise has gotten worse. It seemed to be the fan clutch as it was only really noisy at 50 to 55.
Then hitting 50 got noisy also. Its noticeable at idle sitting but not terrible. It definitely is coming from the front of the engine area and not the alternator bearing.
A ex military 998 mechanic suggested the belts, saw on SS that 998s had a lot of slack anyway, Did tighten up the alternator more but did not help.
Putting the fan clutch on in the field sort of,
was a pain. Any thoughts are welcome.
