O-Ring Seal For Coolant Temperature Sensor (13621433077 )

A common source of coolant leaks is the coolant temp sensor (auxiliary fan switch) located in the lower radiator hose. The rubber o-ring deforms as it's installed. The leak doesn't occur until the sensor is re-used and the o-ring is no longer snug in the hose. This seal is a direct replacement for the sensor o-ring and will stop your leak. Perfect for when nothing is otherwise wrong with the sensor or the hose. Fits all brands of coolant temp sensors, BMW, OEM, aftermarket.
