Tridon Coolant Temperature Sensor TCS121Notes: Spanner: 19mm, Thread: 1/8 - 27 NPT, Replaces original black and red parts.Tridon's coolant sensor range are an ideal replacement for worn and faulty sensors. Manufactured to stringent standards, they have been designed to function to an equivalent standard to the original sensor.The coolant temperature sensor is designed to respond to changes in engine coolant temperature. The sensor is crucial in the control of temperature based functions performed by the ECU (eg spark and fuel timing, instrumentation, etc.).The coolant temperature sensor must be compatible with the vehicle engine management system. Tridon coolant temperature sensors have been carefully researched and engineered to operate within original equipment manufacturer's specifications for each specific application.
