Is there any way to adjust the belt tension pulley on my 94 bonneville 3800
6cyl. It is making very loud noises.. with the hood closed it sounds like a really bad lifter knocking. Please help its driving me crazy. ThanksTo my knowledge there is no adjustment. The tensioners are spring loaded. Perhaps it is worn out, or something else driven by the belt is making the noise. Slip the belt off and try spining the other pulleys by hand.
Good Luck

Sounds like you "may" have a broken harmonic balancer.

In that case, you may need to try a tensioner. If you release the tensioner, does it seem sticky, or too loose? Sorry that I can't be more specific.

Yes it does seem a bit sticky... The poor car has almost 300,000 miles on it. I just changed the waterpump and as soon as I started the car the noise began I am assuming that when I pulled the belt off to change the water pump that something must have gone in the tensioner. But yes a bit sticky but not loose at all. Thanks for the help
