Water temperature sensor.
It monitors engine coolant temperature and sends accurate data to the engine control unit (ECU) and gauge cluster, enabling proper engine management, temperature display, and cooling-system protection. Built to match the original manufacturer’s calibration and connector interface

• Position on Vehicle: Mounted in the engine cooling system, often on the engine block or near the thermostat housing, where it measures coolant temperature for sensor input.
• Cross-Reference / Alternative Numbers: OEM part number: 928 606 201 01 (also shown as 92860620101)
• Applications: Replacement when the original sensor fails, provides inaccurate readings, or exhibits corrosion or damage - ensuring the cooling system and engine management continue to operate correctly.
The coolant temperature sensor is a vital component for engine management: it relays vital temperature information to the ECU, radiator fans, and drivers’ gauges. If the sensor becomes faulty, you may experience incorrect temperature readings, poor cooling-fan operation, unpredictable engine behaviour or even overheating. Replacing it with a quality OE-Match unit ensures accurate temperature detection, proper fan control, consistent engine performance and safeguarding of your cooling system.
When and why to replace:
• Incorrect or fluctuating temperature gauge readings.
• Radiator fan runs constantly or not at all, indicating bad sensor input.
• Engine overheats or cooling system fails to engage properly.
• Visible corrosion, damage or leakage at the sensor housing.
• As part of a cooling-system overhaul or when replacing thermostat, water pump or related components.
