What does an air conditioner belt do?
The AC belt is probably the most simple component of a vehicle’s AC system, but still a very important one. The belt connects the AC compressor clutch to the engine crankshaft, which allows the compressor to be turned via the engine’s power when activated.
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.
What to do if your a / C belt breaks?
The serpentine belt tensioner and serpentine belt may also be damaged. Technicians are to check the A/C system performance and compressor operation using the following repair procedure: Open the hood and inspect the A/C compressor for damage and to see if the compressor is seized.
How long does the AC Delco belt last?
The original lasted 3.5 years, since then it has been a nightmare. The AC Delco belt seems to last the longest. The snapping occurs at various time, hiway speed, idle, I have tried turning the A/C off after each trip and not starting with the A/C on but it doesn’t seem to matter.

Why does my a / C Belt fail every time?
Depending on where it comes to rest, the failing compressor probably takes a lot more torque to get moving. So maybe 1 time out of 5, when the compressor clutch engages, your belt get stressed beyond its design strength, and it starts to fail also. That’s a fair bit of conjecture, though. Anybody know for sure?
