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

A failing air relief valve may initially cause a loss of system pressure or a persistent warning light. If ignored, the system may operate under reduced pressure, leading to inefficient performance or component wear. The worst consequence is potential damage to system components due to inadequate pressure regulation.

Installation Tip

Ensure the valve seat area is clean and free from any debris or old sealant before installing the new relief valve. Avoid applying excessive force when threading the valve, as this can damage the threads in the housing.

Service Note

Inspect the associated pressure lines and seals for any signs of leakage or wear when replacing the relief valve.
