Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

The first sign of a failing belt is often a high-pitched squealing noise, especially during startup or acceleration. If ignored, the belt can slip, leading to reduced or complete loss of function for accessories like the alternator and power steering. The worst consequence is the risk of the belt breaking, causing a sudden loss of all engine-driven accessories and potential engine overheating.

Installation Tip

Always check the condition of the belt tensioner and all accessory pulleys for smooth operation and proper alignment before installing a new belt. Never use a pry bar to force the belt onto the pulleys, as this can damage the belt or pulleys.

Service Note

Inspect the belt tensioner and all accessory pulleys for wear, proper function, and alignment.
