Question How do you R&R tensioner spring and pulley?
Hey folks,
I've got a squeaky serpentine belt that did not stop squeaking upon replacement. I have about 1" of deflection in the belt. I'm assuming the next step is to R&R the tensioner, and maybe also the pulley, which seems to be slightly askew, forcing the belt to ride a little off center towards the front.

Can anyone tell me how to do this on the '87 300D? It's really hard to see what is going on in that dark, cramped spot. Will I have to remove any other items to get to it? Like the fan, or radiator? How do you remove the tensioner and pulley?

Thanks,
Dan
