One of the key aspects of vehicle maintenance is knowing when to check the V-belt for signs of wear. A squeaking or chirping noise when the engine is running may indicate that the V-belt is slipping or becoming detached. Additionally, visible cracks or fraying on the belt are clear indicators that it needs to be replaced. If you notice any leaking fluids, particularly coolant, it may suggest that the water pump is not functioning effectively, potentially due to a damaged V-belt.

Despite their durability, PK belts can wear out, fray, or crack over time due to heat, tension, and environmental factors. A worn belt can lead to slippage, which may cause inadequate power transfer to the alternator and other accessories, leading to electrical failures or battery drain.
