Standard Ignition Engine Cooling Fan Switch P/N:TS-187
Help your cooling fan switch on as coolant temperature climbs with this Standard Ignition switch, the TS-489 engine cooling fan switch (also listed as TS489). It is a direct-fit replacement for the 1987-1988 Sterling 825. See the "Vehicles it fits" section for engine details.
This coolant fan switch senses coolant temperature. When the coolant reaches the switch's calibrated set point, it makes an electrical contact and passes the signal to the fan controller.
Signs this switch may need replacing include a cooling fan that never switches on as the engine warms up, a fan that runs all the time, or a temperature gauge that climbs at idle or in traffic. Other components can cause these symptoms too, so diagnose the cooling system and fan circuit before replacing the switch.
