108-3190 Temperature Sensor — Cat 3408 3512

This temperature sensor monitors the coolant temperature within the engine's cooling system, providing critical data to the engine control module (ECM) for optimal performance and protection. It is built to meet precise OEM specifications, offering accurate readings unlike a faulty sensor that may provide erratic or incorrect data. Operators might observe a fluctuating or inaccurate temperature gauge, engine overheating warnings, or a reduction in engine power if this sensor malfunctions.

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 symptom of a faulty temperature sensor may be an inaccurate or erratic reading on the engine temperature gauge. If ignored, this can lead to the engine operating outside its optimal temperature range, potentially causing increased wear or overheating.

Installation Tip

Ensure the engine is completely cool before attempting to remove the old sensor to prevent injury from hot coolant. Apply a small amount of thread sealant to the threads of the new sensor, but avoid getting sealant into the sensor tip.

Service Note

Inspect the coolant level and condition, and check the thermostat operation when replacing the temperature sensor.
