How to service and repair the drive belt on Chevrolet Express 3500?

The maintenance process for drive belts starts with removing the engine Coolant Reservoir along with the air cleaner intake duct. A 3/8 inch drive wrench should be used to rotate the Drive Belt tensioner arm counterclockwise until you can remove the Drive Belt and reduce tension on the tensioner arm. The new Drive Belt needs installation by following the pulley order starting from the Drive Belt tensioner arm but paying attention to ac line-up rules for specific vehicles. Following steps begin with a 3/8 inch drive wrench to turn the Drive Belt tensioner arm counterclockwise while placing the Drive Belt over the tensioner arm pulley. After the belt installation proceed with gently releasing the tension. Check the Drive Belt route before putting back the air cleaner intake duct and the engine Coolant Reservoir.

How to replace the accessory drive belt on Chevrolet Express 3500?

The first step to replace the accessory Drive Belt begins with removing the air cleaner assembly along with the retaining bolt for the coolant recovery reservoir. Place the reservoir set aside. A breaker bar with hex-head socket should be used to turn the Drive Belt tensioner bolt clockwise until belt tension disappears. Disengage the belt from the pulleys together with the Drive Belt tensioner before you release tension slowly from the Drive Belt tensioner. The first step after removing the breaker bar and socket from the bolt of the tensioner is to perform cleanliness and surface inspection on all pulleys' belt areas. To install the Drive Belt feed it through the pulleys starting with the idler pulley excluded. The installation process requires a breaker bar with hex-head socket to loosen the belt tensioner bolt with clockwise rotation. Place the Drive Belt beneath the idler pulley then loosen the belt tensioner tension slowly by removing the breaker bar combined with the socket. Place and mount the coolant recovery reservoir afterward install its retaining bolt with proper torque set to 11 nm (97 inch lbs.). Reinstall the air cleaner assembly as the last step.
