Help your cooling fan respond to coolant temperature with the Standard Coolant Fan Switch / Engine Coolant Temperature Sender, part number TS-85. It fits many vehicles, among them the 1990 Chevrolet Camaro, 1988-1991 Chevrolet P30 and 1991 GMC P3500. See the Buyer's Guide tab for the full list and engine details.
Standard lists TS-85 under two names: coolant fan switch and engine coolant temperature sender. It is a thermal switch that makes electrical contact when the coolant reaches its calibrated temperature and passes that signal to the fan controller. It is a direct-fit replacement for the listed applications.
- Quality control from start to finish: Standard is a global manufacturer of original equipment ignition products. It controls quality through every stage of manufacturing, from the components to the finished product.
- Calibrated and tested: Every unit is calibrated and tested to confirm that the switch actuates at its specified temperature.
- Factory-set contact point: Each thermal switch is factory-calibrated to make electrical contact at its specified lower-temperature set point.
- Built for the service bay: A robust design and high-grade materials are intended to meet the demands of today's service professionals.
Signs this switch may need replacing include a cooling fan that does not switch on as the engine warms, a fan that runs all the time, or a temperature reading that climbs at idle or in traffic. Wiring, relays and the fan motor can cause the same symptoms, so diagnose the cooling fan circuit before you replace parts.
