Cooling Fans

Cooling Fans: pull air across the radiator when airflow runs short

A cooling fan does one job: it moves air through the radiator core when the vehicle isn't going fast enough to do it on its own. Idling in traffic, crawling on a trail, or sitting in the staging lanes is when engine temps climb, and that's exactly when the fan earns its keep. Electric cooling fans also free up the space and parasitic drag a belt-driven clutch fan takes, which is why so many builders switch to them during a radiator upgrade or an engine swap.

What we stock

There are 82 cooling fans in this category, spanning 9 brands. The current in-stock price range runs from $65 to $532 - that's what's live now, not a standing promise. SPAL dominates the range with 71 of the products, followed by BLOX Racing with four, and single listings from CSF, Cusco, Ford Racing, ISR Performance, QuadBoss, Wehrli and Vibrant.

The SPAL selection covers bulk of the high-output electric side, like the SPAL 500W 16in Drop-In Brushless Fan with Jumper Harness and the lower-profile SPAL 500W 15.2in Flush Mount Brushless Fan. For vehicle-specific setups, there's the CSF Porsche 944 Fan and Shroud Kit, the Ford Racing 2005-2014 Mustang Performance Cooling Fan, and the QuadBoss Polaris 400L Fan Motor for powersports.

How to choose

The first split is universal versus vehicle-specific. A drop-in or flush-mount brushless SPAL fan lets you build airflow around your own shroud and radiator, which suits swaps and custom cores - you'll do more of the wiring and bracketry yourself. A kit like the CSF 944 fan-and-shroud or the Ford Racing Mustang fan bolts into a known application with far less fabrication.

The second is mounting depth. A 16-inch drop-in moves more air but needs the room in front of the core; the 15.2-inch flush-mount trades some frontal area for a slimmer stack when clearance is tight. Match the fan diameter and depth to the radiator you're running before you buy.

What else you need with it

A fan is part of the cooling loop, so plan the rest of it. Pair a new fan with the right radiator, and check the plumbing with the fittings and adapters in the same section. A brushless fan pulling serious current also leans on the charging system, so it's worth looking at batteries while you're in here. Browse the full Engine Components section for gaskets, pumps and the rest of the build.

Fitment and ordering

Fitment data is listed on 5 of these products, covering years 1983 through 2016. Named applications include the Ford Mustang, Porsche 944, Mitsubishi Lancer Evolution, Polaris 400L and Chevrolet 6.6L LML Duramax - treat that as a sample of coverage, not the full list. If you're not sure a fan clears your core or matches your harness, call fitment help at 813-535-5801 or reach us through contact us before ordering.

All orders ship free, and Affirm and Katapult financing is available on the higher-priced brushless kits.
