CARQUEST by BWD is an aftermarket leader, providing a premium line of engine management products. BWD manufactures and distributes high technology critical components for late model domestic and import vehicles. BWD is constantly evolving to give customers the competitive edge they need to compete in today’s ever-changing marketplace.

Product Features:
  • In design, we specify custom wax formulations that will expand when heated, activate a snap action electrical contact and transfer the electrical signal to the fan controller
  • In manufacture, we custom form the wax pellets for different temperature range specifications. All units are calibrated & tested to confirm switch actuation at their specified temperature
  • The switch is designed using a formed bimetallic contact arm. The bimetal contact movement is achieved using the different expansion rates of two metals fused together. This is a creep action device, provides precise performance
  • In production, all thermal switches are factory-calibrated to make electrical contact at the specified lower-temperature set point
  • Our switches feature a robust design with high grade materials to meet the stringent demands of today's service professional

      Hi Ray, glad to help! The coolant temperature sensor is used to measure the temperature of the engine coolant of an internal combustion engine. The readings from this sensor are then fed back to the Engine control unit (ECU). This data from the sensor is then used to adjust the fuel injection and ignition timing. On some vehicles the sensor may be used to switch on the electronic cooling fan. The data may also be used to provide readings for a coolant temperature gauge on the dash. The coolant temperature sensor works using resistance. As temperature subjected to the sensor increases the internal resistance changes. Depending on the type of sensor the resistance will either increase or decrease.
