Signal the electric cooling fan when engine coolant reaches its set temperature with the Standard Ignition switch TS-152, a coolant fan switch from a global manufacturer of original equipment ignition products. It is a direct-fit replacement for the 1981-1985 Mazda GLC (engine: All). The switch threads into its port and connects through a plug-in connector.
- Calibrated set point: Each thermal switch is calibrated at the factory to make electrical contact at its specified lower-temperature set point. Every unit is tested to confirm it actuates at that temperature.
- Signal to the fan: When the switch reaches its set point, the contact closes and passes the electrical signal on to the fan controller.
- Quality control: Standard Ignition keeps quality control in place throughout manufacturing, from individual components through to the finished switch.
- Built for technicians: The switch has a robust design and high-grade materials, intended to handle the stringent demands of today's service professional.
Specifications: 12-volt switch with a round metal housing in a gold finish and a 16 mm x 1.50 thread. It has one male blade terminal in a round, plug-in male connector. The wiring harness, mounting hardware and mounting brackets are not included. Quantity per application: 1. Country of origin: Italy.
Signs that a coolant fan switch may need replacing include an electric cooling fan that does not come on as the engine warms up, temperature readings that climb at idle or in traffic, and a fan that runs constantly. Other faults can cause these symptoms, so diagnose the cooling system before replacing the switch.

Frequently Asked Questions
What vehicle does the Standard Ignition TS-152 fit?
It is listed for the 1981-1985 Mazda GLC with engine code All. One switch is used per vehicle.
Is this a Standard Ignition 1 terminal coolant temperature switch?
Yes. TS-152 is a coolant fan switch with a single male blade terminal. It makes electrical contact at its calibrated temperature set point to signal the fan controller.
What thread size and voltage does TS-152 use?
It has a 16 mm x 1.50 thread and a round metal housing with a gold finish. It is rated for a 12-volt system.
Is a wiring harness or mounting hardware included?
No. The wiring harness, mounting hardware and mounting brackets are not included. See the vehicle service information for installation requirements.
How do I know if my coolant fan switch has failed?
Possible signs include a cooling fan that won't turn on as the engine warms, temperatures climbing in traffic, or a fan that never shuts off. Other faults can cause these too, so diagnose the circuit first.
