- Belt slippage under engine load
- Loss of drive to the power steering to air pump circuit
- Cracking, glazing, or heat-related belt wear
- Noise caused by an aging V-belt profile
Installation Notes and Tips
Verify belt routing against the vehicle’s accessory drive layout before installation. Confirm the belt profile, effective length, and outside circumference match the original specification for the power steering to air pump drive. Inspect pulleys and alignment at the same time, since worn or misaligned components can shorten belt life and increase noise.
