How do I stop my car belt from slipping?
You should apply belt dressing to your serpentine belt every month or every 3,000 miles to prolong its life and to prevent it from slipping. Sometimes, depending on the cause of the squeak. Belt dressing is intended as a tool to help you maintain your belts.
Can a broken AC compressor cause the serpentine belt to snap?
If the AC clutch bearing seizes while the AC compressor is not operating, the belt can snap then as well. Replacing the serpentine belt tensioner and idler pulley at the same time as the belt is always a good idea. They wear out too!
What happens when the AC compressor in your car fails?
So, when the AC compressor fails, you’ll notice high degrees and hot airflow inside the car. However, there are three possible reasons behind the hot airflow inside your vehicle; the first could be a refrigerant leak, the second is a low refrigerant, and the third is a failing AC compressor that needs replacement.
What happens when the clutch on a compressor goes bad?
When the switch goes bad, it will no longer be able to measure pressure and will leave the clutch engaged the entire time. This switch is located on the metal canister next to the compressor. It is screwed into the refrigerant canister and has two wires extending from it toward the wiring harness.
What causes a serpentine belt to get stuck?
The main reason, in most cases, will be a stuck pulley from one of the devices (alternator, AC compressor, power steering pump etc) or a tensioner. A stuck pulley is mostly caused by a worn out bearing. The belt slides over a motionless pulley causing extensive friction, heat and the recognizable sound.
What causes a V-belt to slip in a car?
Belt slippage occurs whenever torque demand exceeds the available friction between a V-belt and one or more of the pulleys (sheaves). When this occurs, the belt begins to slide backwards a bit as it moves with the pulley. This action is similar in two ways to slightly slipping the clutch in a manual transmission car:

How to tell if the clutch or the AC compressor is bad?
Place a mechanic’s stethoscope probe on the top of the non-moving part of the clutch while the engine idles. Have your assistant turn on the AC controls to maximum. Listen for any internal buzzing or clicking from the clutch.
What to do if your car AC compressor is making a noise?
Spray the belt down with water using a spray bottle and the noise problem should be fixed. If the noise persists, open the hood of your car and check the belt for any wear and tear. If you notice any signs you may need to replace it.
