What Causes a Squeaking Belt?
Several factors can contribute to a squeaking belt. These include:
- Wear and Tear: Over time, belts become worn, cracked, and glazed, losing their grip and causing slippage and squeaking.
- Misalignment: A pulley that’s not properly aligned can cause the belt to rub against its edges, creating friction and noise.
- Moisture: Rain or a leaking coolant hose can make the belt slip, resulting in a temporary squeak.
- Cold Weather: In cold temperatures, belts can become stiff and more prone to squeaking.
- Bad Tensioner or Idler Pulley: A failing tensioner or idler pulley can cause the belt to loosen and squeak.
Diagnosing the Squeaking Belt
Before you start fixing the problem, you need to pinpoint the source of the squeak. With the engine running (be extremely careful!), listen carefully to locate the squeaking sound. Use a long screwdriver or a piece of hose as a stethoscope to pinpoint the noise. Be cautious around moving parts.
Identifying the Specific Belt
Modern cars typically have one serpentine belt that powers multiple accessories like the alternator, power steering pump, and air conditioning compressor. Older vehicles may have multiple belts. Once you locate the squeaking belt, you can begin troubleshooting.
