Looking for a Sonata switch that tells the electric cooling fan when to run? The Four Seasons Engine Cooling Fan Switch 36539 is an engine-mounted cooling fan temperature switch, built as a direct-fit replacement for the listed 1989-1994 Hyundai Sonata applications and cataloged for the right-side position. See the Buyer's Guide tab for engine details.
This switch senses engine temperature and opens or closes the cooling fan circuit, so the electric fan is designed to switch on when the engine needs extra cooling. If a failed fan switch is behind your cooling fan trouble, this unit replaces it.
- Brass construction: the brass body is used for accurate temperature sensing.
- Zinc-coated terminal: the terminal is zinc coated to help resist corrosion.
- Sealing parts included: comes with the gaskets, O-rings or seals needed to properly replace the switch.
- Vehicle-specific application: cataloged for the listed Hyundai Sonata applications.
Four Seasons engineers and tests its products, drawing on more than 50 years of mobile A/C experience.
Signs this part may need replacing: an electric cooling fan that never switches on, a fan that runs all the time, or engine temperature that climbs while idling or in slow traffic. Relays, wiring and the fan motor can cause the same symptoms, so diagnose the cause before replacing the switch.
