This sensor and cooling component is integral to monitoring and regulating the engine's operating temperature and related parameters. Manufactured to meet Volvo and Renault Trucks' rigorous standards, it provides accurate readings and reliable function, unlike failing sensors that can give false information or cease to operate. Operators may notice inaccurate temperature gauge readings, engine overheating warnings, or the activation of a 'check engine' light when this component is faulty.

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.
A malfunctioning sensor may initially cause the temperature gauge to read incorrectly or fluctuate erratically. If the sensor fails completely, the engine control unit may not receive temperature data, potentially leading to overheating without warning or triggering a 'check engine' light. This can result in reduced engine performance or the engine entering a limp-home mode.
Ensure the electrical connector is clean and free of corrosion before plugging in the new sensor. Avoid applying excessive force when tightening the sensor into its housing to prevent damage.
Inspect the radiator, coolant hoses, and water pump for any signs of leaks or wear when replacing this sensor.
