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 temperature sensor may initially cause the temperature gauge to fluctuate erratically or read incorrectly. If the sensor fails completely, the engine may enter a 'limp home' mode, or the operator might receive persistent overheating warnings. Ignoring these symptoms can lead to engine damage due to uncontrolled high temperatures.

Installation Tip

Ensure the engine is completely cool before attempting removal to avoid burns. Apply a small amount of thread sealant to the new sensor's threads, but avoid getting any into the sensor tip.

Service Note

Inspect the coolant level and condition, and check the radiator and fan for proper operation.
