317-9564 Temperature Sensor — Cat

This temperature sensor monitors the engine coolant temperature, providing critical data to the engine control module (ECM) for optimal performance and protection. It is built to CAT's rigorous specifications, ensuring accurate readings unlike a faulty sensor that may provide erratic or incorrect data. Operators might observe fluctuating temperature gauge readings, unexpected fan operation, or engine derate warnings when this sensor fails.

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 a failing temperature sensor is inaccurate or fluctuating readings on the engine temperature gauge. If left unaddressed, the ECM may receive incorrect data, leading to improper fuel mixture, inefficient cooling, or unnecessary engine derating. The worst consequence is potential engine damage due to overheating if the cooling system is not managed correctly.

Installation Tip

Ensure the sensor port is clean and free of debris before threading in the new sensor to guarantee a proper seal. Avoid using excessive force when tightening, as this can damage the sensor threads or the engine block.

Service Note

When replacing the temperature sensor, check the coolant level and condition, and inspect the radiator and hoses for any signs of leaks or wear.
