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

An initial sign of failure may be an erratic or inaccurate temperature gauge reading. If left unaddressed, the engine control module may receive incorrect data, leading to inefficient fuel consumption or potential overheating. This can result in reduced engine performance and increased wear on internal components.

Installation Tip

Ensure the sensor port is clean and free of debris before installation to guarantee a proper seal. Avoid overtightening the sensor, as this can damage the threads in the engine block or the sensor itself.

Service Note

Inspect the engine wiring harness connected to the sensor for any signs of damage or corrosion.
