342-2924 Water Temperature Sensor — Cat C13 C15

This is the engine water temperature sensor, which monitors the coolant temperature and sends signals to the engine control module (ECM) or gauge. It is manufactured to meet OEM specifications, providing accurate readings unlike a faulty sensor that might give erratic or incorrect temperature data. Observable symptoms of a bad sensor include the temperature gauge reading incorrectly, the engine running too hot or too cold, or poor fuel economy.

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 inaccurate temperature reading on the dash gauge, such as showing the engine is cold when it's hot or vice versa, is a common initial symptom. If the sensor fails completely, the gauge may read maximum temperature or remain at zero, potentially leading to the engine running inefficiently or overheating. Ignoring a faulty sensor can result in increased fuel consumption or damage from improper temperature management.

Installation Tip

Ensure the sensor port threads are clean and free of debris before installation. Avoid using excessive force when threading the sensor, as this can damage the port or the sensor itself.

Service Note

When replacing the water temperature sensor, check the condition of the thermostat and radiator hoses for any signs of wear or leaks.
