    Crappy aftermarket tensioners

    I am discovering that the aftermarket non Saturn belt tensioners absolutely suck.

    It looks like you can still get the 3rd gen S series tensioners but that's it.

    Has anyone tried to retrofit the 3rd gen tensioner on the 1st or 2nd gen blocks?

    This is starting to get really old replacing the same parts year after year.

    It seems to be the tensioner itself. I've tried smaller belts and that only works for a short while.

    They are garbage, but I thought you could still order the AC Delco one? (3x the price or so)

    We had to install an aftermarket tensioner on a customer's car a week ago because GM does not have any more of the OEM ones. We had to replace the first aftermarket one immediately because it wasn't tight enough and the belt would squeak. Also we could not get a factory belt. This was on a 94 SOHC with P/C and A/c.

    Yeah they are worthless. They make that terrible chatter sound and wear out really quick. I need to find a solution.

    Put an idler in place of current tensioner and fab up the alternator mounting to pivot and have a bolt type adjuster.

    I'd like to try and recreate the factory one if possible.
