Tridon Coolant Sensor TCS117 Ultra-Ceramic The thermo fan switch is

The thermo fan switch is designed to control operation of the electric thermo fan(s)

which prevents corrosion for a longer life and provides an easier fit to your vehicle

Heat tolerant seals and O-rings

which is a better choice for the environment - particularly with off-road driving

Disc brake pad wear sensors are designed to �fail� as brake pads wear

Tridon Coolant Sensor TCS117 Ultra-Ceramic The thermo fan switch isThe 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; the Tridon coolant temperature sensor range has been carefully researched and engineered to operate within original equipment
