What It Helps Address

• Radiator fan not switching on at the proper temperature
• Cooling fan staying on longer than expected
• Intermittent fan operation caused by a worn switch
• Low-speed engine fan control issues on select Mitsubishi applications
• Fan circuit faults related to a damaged threaded switch assembly

Installation Notes and Tips

Verify the thread size, connector style, and terminal layout before installation. This TS-297 uses a plug-in connection with 2 blade terminals and no wiring harness, so the vehicle connector must match the switch design. Confirm the application location, such as radiator-mounted or low-speed fan use, against the vehicle service information before replacement.

Quality Assurance

Standard Ignition supplies electrical and thermal control components for automotive service applications. TS-297 is built with a metal housing and brass finish for under-hood durability in supported 12-volt cooling fan circuits.
