The AC belt can stretch, wear or even break. Replacing the belt is a very straightforward procedure. A word of note before you start: The A/C system is charged with a refrigerant that is both dangerous and illegal to discharge into the atmosphere. If you are going to be working on the system make sure you have the refrigerant properly evacuated and reused or disposed of.

You will need to remove the shroud for the radiator before beginning this job. Please see our article on shroud removal for further assistance.

Before you do any work on your car it is important that you wear safety glasses, work gloves and dispose of all fluids in a safe manner. Coolant is poisonous and should be treated as such. Animals and small children have been known to die from ingesting coolant. If you have to jack up your car, make sure to use jack stands and chock your wheels as well as applying the parking brake. Protect your eyes, hands and body from fluids, dust and debris while working on your vehicle. If you're working with the electrical system, disconnect the battery before beginning. Always catch fluids in appropriate containers and properly dispose of any fluid waste. Recycle parts, packaging and fluids when possible. Never work on your vehicle if you feel the task is beyond your ability. Always wear eye and hand protection and disconnect the battery.

Use a 19mm closed end wrench.

The belt is now free.

The belt is now free. Installation is the opposite of removal. When a new belt is put in place, move the tensioning pulley so there is no slack.
