Detailed Product Description

The Four Seasons 37138 engine cooling fan is a 12-inch puller auxiliary fan intended for vehicles that need additional radiator airflow. It is a direct fit for many applications across Subaru Forester, Subaru Impreza, Subaru Legacy, Subaru Outback, Subaru WRX, Subaru WRX STI, and Subaru BRZ model years listed in the fitment data, along with a broad range of Hyundai, BMW, Ford, Toyota, Volkswagen, and other vehicles. This part cross-references Gates 3910 for the same application.

With a 12-volt electrical setup, 2-terminal male blade connection, and 12.1 amp draw at high speed, the 37138 is a straightforward option for cooling system service where airflow and packaging size matter. The 12-inch diameter and 2.56-inch depth help it fit compact engine bays while still delivering strong airflow for radiator-mounted use.

What This Fan Helps Address

• High engine temperatures during stop-and-go driving
• Reduced airflow through the radiator at low vehicle speed
• Cooling system strain after fan failure or weak fan performance
• Need for auxiliary cooling on performance or heavy-duty cooling setups
• Airflow support for vehicles with limited mechanical fan clearance

Installation Notes and Tips

Verify available space before installation, especially the 12-inch diameter and 2.56-inch depth. This is a puller-style fan, so it should be positioned to draw air through the radiator. Controls are not included, so the vehicle’s fan control strategy or aftermarket control setup must be confirmed before wiring.
