I have a 2002 Saturn Sl1 and I replaced the belt tensioner but it still makes a knocking noise also. I'm guessing I should get a belt that looks like the old one with the polymer pulley but the heavy duty metal pulley I have now is probably contributing to the noise.
It makes a knocking noise when I go in reverse and hold the brake or when I am in drive or when I turn the A/C on.
I love this site :-)
have the same problem?
