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 relay may initially cause intermittent operation of the controlled component, such as lights flickering or an engine that sometimes fails to crank. If the relay fails completely, the associated electrical system will cease to function altogether. Ignoring a faulty relay can lead to electrical system malfunctions and potential damage to other components.

Installation Tip

Always disconnect the battery before replacing any electrical relay to prevent short circuits. Ensure the new relay is firmly seated in its socket and the wiring connections are secure.

Service Note

Inspect the wiring harness and connectors associated with the relay for any signs of corrosion, damage, or loose connections.
