    Default Chevy Avalanche serpentine belt replacement

    Replacing the serpentine belt on your Avalanche is similar to any GM truck these days.

    Look for the grey idler pulley, hook in a 5/8 socket on a 1/2 drive breaker bar and pull. Make sure you have a good connection.

    The whole process takes about 5 minutes, you should have a diagram on your fan shroud to show how the belt gets routed if you forget.

    Chevy parts www.gmpartsclub.com You can find the serpentine belt here for all chevy trucks.

    Default Two belts in the Avalanche

    Most Avalanches have A/C anymore, the AC is driven off a 2nd belt for any Avalanches (2002-2005 at least). It's behind the big serpentine and has it's own idler adjuster.
