Drive Belt Replacement: When Should You Change It?
The drive belt transfers engine power to accessories such as the alternator, air conditioning compressor and other belt-driven components.
A worn belt can affect multiple systems.
Signs of a Worn Drive Belt
Cracks
Visible cracking along the belt ribs can indicate aging or deterioration.
Squealing Noise
A squealing sound may occur when the belt slips.
However, tensioners, pulleys and other components can also cause belt noise.
Frayed Edges
Damaged belt edges may indicate misalignment or component problems.
Glazed Surface
A shiny or glazed belt surface can indicate excessive slipping or heat.
Belt Vibration
Unusual movement may indicate a problem with belt tension or pulley alignment.
What Can Damage a Drive Belt?
Common causes include:
- Age
- Heat
- Oil contamination
- Coolant contamination
- Incorrect tension
- Pulley misalignment
- Worn tensioner
Finding the cause is important before installing a new belt.
Should the Tensioner and Pulleys Be Checked?
Yes.
A new belt can wear prematurely if a pulley or tensioner is damaged.
During replacement, inspect the complete belt drive system.
Choosing a Replacement Belt
Check:
- Belt length
- Number of ribs
- Rib profile
- Engine specification
- OE number
- Belt routing
