Get strong airflow for steady cooling with 2150 CFM radiator fans when towing or idling in traffic. Often used as pusher fans in front of the radiator, they can be reversed with polarity and a custom shroud if you need a puller. Install is straightforward, though basic mounting ties may need extra care, and high-speed operation can be louder and draw more power at idle.
Yes, you can reverse polarity to change rotation. Many units are intended as pusher, so for puller use plan on a custom shroud. Check that the included shroud isn't too open, since open shrouds aren't effective as pullers. Verify clearance and airflow direction before final mounting.
Use relays to switch between series (half speed) and parallel (high speed) to reduce noise and current draw at idle. Tie half speed to the A/C compressor for condenser airflow, then switch to high when temps climb. A temperature probe around 180° can trigger the change. Check alternator capacity, especially with a trailer plugged in.
Measure total depth including the motor, then the shroud depth alone to check space between radiator and engine. Also measure from the mounting hole centerline to the shroud edge if trimming might be needed. Mock up the fan to verify it clears pulleys, belts, and nearby lines before final install.
A dual 2150 CFM setup in front of the radiator can help keep temps much cooler when towing or idling in traffic. Consider pairing fans and placing them as pushers for condenser airflow at idle. Wire cleanly and confirm your charging system can handle the added load at idle.
Installation is typically straightforward, but verify mounting tie keepers hold firmly as some can slip. If the ties don't bite, use alternative brackets or through-core hardware rated for radiators. Confirm shroud and motor clearance to the water pump and hoses before tightening everything down.
