107-8618 Temperature Sensor — Cat 320D

This is a CAT Temperature Sensor, which accurately measures the engine coolant temperature and sends this data to the engine control unit (ECU) or gauge. It is built to precise specifications, ensuring reliable readings unlike a faulty sensor that can provide inaccurate information, leading to incorrect engine management or misleading operator alerts. Operators may observe erratic temperature gauge readings, unexpected fan activation, or engine derating if this sensor is malfunctioning.

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 read inaccurately, either too high, too low, or erratically. If ignored, this can lead to the engine control unit making incorrect adjustments, potentially causing poor performance or activating cooling fans unnecessarily. The ultimate risk is the engine operating outside its optimal temperature range, leading to increased wear or damage.

Installation Tip

Ensure the sensor port in the engine block or cylinder head is clean and free of debris before threading in the new sensor. Avoid over-tightening, which can damage the sensor threads or the engine block.

Service Note

Check the coolant level and condition, and test the thermostat's operation when replacing the temperature sensor.
