Question about 2001 GMC Sierra 2500HD
Posted by Anonymous on
Check alternator output against specs. I suspect that the issue is with the belt not being properly lined up with the pulleys

there is a vacuum line PCV that goes to the drivers valve cover the hose could be broken down and causing the noise could be other things but that is the first thing that comes to mind

The A/C pully is supposed to spin freely until the AC is activated to run.. The cranshaft pully does not. Replace the tensioner pully. The belt has to fit in between the grooves on the pullys.

it is decieving. if the tensioner has an extension of about two inches from the base, it takes a 15 mm to lift it, be easy, make sure the wrench is not going to touch anything as you release it after taking the belt off

Look at the front of the tenisinor there is a squre slot in it a 3/8 ths extention for a 3/8 ths drive scoket wrench will fit in it. Put the extention on the wrench and put the end in the slot then push toword the engine this will move the tenisitoner and release the tention and then you will be able to remove the belt.
