    Q:
    How to Replace the Drive Belt for the Air Conditioning Compressor on GMC Sierra 3500 Classic? Posted by Customer
    A:
    Beginning the Air Conditioning Compressor Belt replacement requires the removal of the accessory drive belt. Fix a ratchet in the air conditioning belt tensioner adapter opening then spin the A/C belt tensioner clockwise to relax the belt tension before pulling the A/C belt from the pulleys and releasing tension off the A/C belt tensioner before removing the ratchet. Perform a cleaning and inspection of all belt surfaces across the pulleys. To install the A/C belt start by placing it over the crankshaft balancer followed by inserting a ratchet into the A/C drive belt tensioner adapter opening before rotating the A/C belt tensioner clockwise to let the tension unwind. Correctly position the A/C belt above the tensioner pulley followed by the A/C compressor pulley and reduce the tension using the A/C belt tensioner before unfastening the ratchet. Before installing the accessory drive belt check that the A/C belt has correct installation alignment.
