Cooling Fan Controller for 1992-2003 Hyundai Elantra & More - Hayden 3647

Keep your electric cooling fan switching on at the right temperature with the Hayden Engine Cooling Fan Controller 3647, a direct-fit switch that monitors engine temperature and signals the electric fan to run. It fits many vehicles as a vehicle-specific replacement, among them the 1975-1978 and 1983-1987 Dodge Charger, the 1992-2003 Hyundai Elantra and the 1989-2003 Hyundai Sonata, along with a wide range of BMW and Chrysler models. See the "Vehicles it fits" section for the full fitment.

Key features:

• Brass construction for accurate temperature sensing.
• Zinc-coated terminal to resist corrosion.
• Vehicle-specific application engineered and tested for cooling-system duty.
• Includes the gaskets, o-rings, or seals needed to properly replace the product.

As the temperature-sensing switch in an electric cooling-fan circuit, it reads engine temperature and switches the fan on as the engine heats up, then off as things cool down. If a fan that never comes on — or one that runs constantly — traces back to a failed controller, this replaces it. Diagnose the cause before replacing, since fan issues can also stem from wiring, relays, or the fan motor itself. Backed by Hayden's decades of automotive cooling experience.
