474-3231 Temperature Sensor — Cat C13

This Temperature Sensor is an electronic component that monitors the engine coolant temperature and transmits this data to the engine control module (ECM). Built to precise specifications, it provides accurate readings that are essential for optimal engine performance and protection, unlike a faulty sensor that might give erratic or incorrect readings. Operators may notice the engine overheating warning light illuminating, erratic temperature gauge readings, or the engine entering a reduced power mode 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

The first sign of a failing temperature sensor might be an inaccurate reading on the temperature gauge or the illumination of the engine warning light. If left unaddressed, the ECM may not receive correct data, leading to inefficient fuel management or the engine entering a protective limp-home mode. The ultimate risk is engine damage due to undetected overheating.

Installation Tip

Ensure the sensor port is clean and free of any debris or old sealant before installation. Do not overtighten the sensor, as this can damage the threads or the sensor body.

Service Note

Inspect the wiring harness and connector for any signs of damage or corrosion when replacing the temperature sensor.
