T25,G2 Water Temperature Sensor (White) - 1.9 (DG,SP)

This white coolant temperature sensor is used on a wide range of classic Volkswagen petrol engines to control manifold intake heating and warm-up functions. Operating at 55/65°C, it ensures correct engine behaviour during cold starts and warm-up by signalling temperature data to the intake heating or control system.

A failed sensor can cause poor cold running, hesitation, excessive fuel consumption, or intake icing on carburettor engines. This replacement sensor features the correct 2-pin terminal, M10x1 thread, and original white colour coding, which is critical as VW temperature sensors are calibrated by colour and must not be mixed.
