383-2990 Temperature Sensor — Cat 3508 3512

This is a temperature sensor, an electronic device that measures the temperature of engine coolant or oil and transmits this data to the engine control unit (ECU) or gauge. Constructed with durable materials and precise sensing elements, it provides accurate real-time temperature readings essential for optimal engine performance and protection, unlike a faulty sensor that can give misleading information. Operator symptoms of a malfunctioning temperature sensor include inaccurate temperature gauge readings, overheating warnings, or the engine running in a reduced power mode.

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 indication of a faulty temperature sensor is often an erratic or incorrect reading on the temperature gauge. If ignored, this can lead to the engine operating outside its optimal temperature range, potentially causing damage or reduced performance.

Installation Tip

Ensure the sensor port is clean and free of debris before threading in the new sensor to guarantee a proper seal. Do not overtighten the sensor, as this can damage the threads or the sensor body.

Service Note

Inspect the engine's cooling system and verify coolant levels when replacing the temperature sensor.
