It is a direct-fit replacement for the listed applications and fits many vehicles, including the 1979-1984 Dodge Colt, 1988 GMC R1500 Suburban and 1985-1986 Dodge Conquest. See the "Vehicles it fits" section for the full list of vehicles and engine details. The catalog lists it for the right-hand position.
This thermal switch responds to coolant temperature. When it reaches its calibrated set point, it makes electrical contact and passes that signal to the fan controller so the cooling fan can engage.
- Calibrated and tested: Every unit is calibrated and tested to confirm the switch actuates at its specified temperature.
- Set-point contact: Each thermal switch is factory-calibrated to make electrical contact at its specified lower-temperature set point.
- Controlled quality: Standard Ignition is a global manufacturer of original equipment ignition products. It keeps full quality control over the process, from componentry to the finished product.
- Built for technicians: A robust design and high-grade materials are meant to handle the demands of today's service professional.
Signs this part may need replacing include a cooling fan that stays off as the engine warms up, temperatures climbing in stop-and-go traffic, or a fan that never shuts off. Other cooling-system faults can cause the same symptoms, so diagnose the cause first. If a failed fan switch is the problem, TS-144 replaces it.
