What causes the serpentine belt to break on a GM Truck?

Some customers may comment about an underhood rattle noise heard on acceleration or a sudden loss of A/C system performance. This condition may be caused by liquid slugging of the A/C compressor. This condition may cause an internal failure in the A/C compressor. The serpentine belt tensioner and serpentine belt may also be damaged.

When does the a / C belt break in a GM Truck?

It is just at low speeds, and usually happens when the unit has been driven a short time, shut off and then restarted. Like a trip to the store. When restarted and driving away at about 20 MPH the chatter occurs and then the belt breaks. It is a clean break, just like it snapped in half.
