Hayden Engine Cooling Fan-Universal P/N:3920
Add supplemental cooling airflow with the Hayden Auxiliary Cooling Fan 3690, a 14-inch reversible electric fan kit that moves air across the radiator or condenser to help manage coolant temperatures. It's a universal fan — not a direct OE replacement — so it's listed against a broad range of vehicles including the 1994-2003 Dodge Ram 1500 3.7L / 3.9L / 4.7L / 5.2L / 5.7L / 5.9L and 1988-1999 Chevrolet C1500 4.1L / 4.3L / 5.0L / 5.7L / 6.2L / 6.5L / 7.4L; see the "Vehicles it fits" section for the full list, and always measure your core and verify available space before ordering.
Motors are built and tested to Hayden's quality specifications, backed by decades of automotive cooling experience. Because fit varies by vehicle, confirm the fan clears the core and surrounding components before you buy.

Is this a direct replacement for my vehicle's fan?
