Standard Ignition Engine Cooling Fan Switch P/N:TS-139
Standard Motor Products
Help your electric cooling fan switch on when the engine warms up with this Standard Ignition switch, part number TS-116. This engine cooling fan switch (coolant fan switch) senses coolant temperature and sends an electrical signal to the fan circuit. It is a direct-fit replacement for the listed applications: the 1979 Plymouth Arrow Pickup and the 1981-1984 Toyota Starlet. See the "Vehicles it fits" section for engine details.
Signs this part may need replacing include a cooling fan that doesn't come on as the engine warms up, a temperature gauge that climbs at idle or in traffic, or a fan that runs constantly. These symptoms can have other causes, so diagnose the cooling system before replacing the switch. If a failed fan switch is the cause, the TS-116 replaces it.
