How to change serpintine belt 2002 3.5 aurora


Use a 3/8" breaker bar to move the belt tensioner. While holding pressure on the tensioner, remove the serpentine belt from any of the pulleys. Gently release pressure from the tensioner. Remove the old belt and replace with the new one. Reapply pressure to the tensioner and pop the belt over the last pulley.

Put new alternator on now at idle with a/c on while in gear terrible noise somewhere around serpintine belt area.put it in neutral or park and noise stops.same time this started the driverside a/c zone...


replacing the alternator and removing the belt and tensioner may have caused a problem with the a/c compressor and bearings , when you replaced the alternator did you replace the belt and tensioner if so it may have added enough pressue on the a/c bearings to cause the problem , if you didn't replace them it the a/c clutch bearing may be bad

I HEAR A LOUD WHINNING NOISE FROM UNDER THE HOOD


Yes there is a bearing in the AC clutch assembly, and the bearing can be changed with out swapping out for a whole new AC compressor unit or even taking the unit out. 
The other thing to you may want to check is the Serpentine belt tensioner. The tensioner then to break apart and or when the clutch activate put's more pressure on the system and the idler pully bearing could alsy be the problem. 
Spray some water on the fan belt whale the engine is running and see if the noise goes away and comes back as the water dry's. If the noise goes away then it's just a worn belt and need to be changed or you may want to do the quick fix and buy Fan belt dressing. 
Good luck and hope this helps

Serpintine belt on replacement on 2002 chevy trailblazer


You should not have to take off your fan or your shroud to replace the belt. Its all under a tensioner pulley you have to put a 18 mm wrench on and pull towards the inside and you should see the belt loosen up enough to take belt off.
