This water sensor accurately monitors the engine coolant temperature, providing critical data to the engine control unit (ECU) for optimal performance and protection. Manufactured to Volvo's high standards, it offers reliable readings, unlike a faulty sensor that can send incorrect information, leading to overheating or inefficient operation. Operators might observe inaccurate temperature gauge readings, the engine overheating warning light illuminating, or the engine running poorly if this sensor fails.

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.
An inaccurate engine temperature gauge reading, or the engine overheating warning light illuminating unexpectedly, are the primary indicators of a faulty water sensor. If the sensor provides incorrect data, the engine management system may adjust fuel delivery improperly, leading to poor performance or potential overheating. Ignoring these symptoms can result in engine damage.
Ensure the sensor port in the engine block is clean and free of corrosion before threading in the new sensor. Avoid using excessive force when tightening, as this can damage the sensor threads or the engine block.
Inspect the thermostat and radiator hoses for signs of wear or blockage when replacing the coolant temperature sensor.
