Fekuar 6" Slim Radiator Cooling Fan 650CFM — 12V 80W Push/Pull High-Flow for Tight Engine Bays

Fekuar's 6-inch slim 650CFM radiator cooling fan is a compact, high-flow 12V/80W universal fan designed for push or pull mounting to efficiently cool radiators and engine bays where space is limited.

This slim-profile fan delivers up to 650 cubic feet per minute (CFM) of airflow from a 10-blade straight design while occupying minimal depth—ideal for classic cars, hot rods, and modified engines that require improved cooling but have crowded engine bays. It works as either a push or pull fan, fits many popular V6 and V8 engines, and targets not just the radiator but the A/C condenser, intercooler, oil cooler, and transmission area to lower operating temperatures under load.

How does the slim form factor benefit cramped engine bays?

The narrow housing allows installation where full-depth fans won't fit, freeing room for engine accessories or custom modifications. Its compact size reduces interference with shrouds, brackets, and aftermarket components while still moving strong airflow.

• 6-inch blade-to-blade diameter fits small shrouds and tight mounts
• Slim thickness clears close-set radiators and condensers
• Leaves extra space for headers, intake, or turbo plumbing
• Easy routing of hoses and wiring around the fan housing

Can I use this fan for push or pull configurations?

Yes—the Fekuar fan is engineered for both push and pull setups, so you can mount it in front of or behind the radiator depending on your vehicle layout. This flexibility simplifies retrofit projects and replacements without changing the fan orientation.

• Push mounting clears space in front of the radiator
• Pull mounting improves radiator surface airflow from behind
• Universal bolt pattern and compact frame simplify swaps
• Works with most electric fan relays, thermostats, and controllers

What performance can I expect from a 6" 650 CFM fan?

The fan produces strong directed airflow for its size—up to 650 CFM—making it effective at assisting or replacing larger fans in short-depth installations. While not a replacement for multiple large fans on extreme cooling builds, it meaningfully lowers temperatures for many vintage and performance engines.

• Maximum airflow: 650 CFM for rapid heat dissipation
• Power: 12V, 80W motor for reliable continuous operation
• 10 straight blades optimized for concentrated airflow
• Suitable as primary support for radiators, condensers, and coolers

Which vehicles and systems is this fan compatible with?

The Fekuar 6" slim fan is aimed at hot rods and classic American engines and fits a long list of V6 and V8 displacements commonly used in restorations and swaps. It cools more than the radiator—A/C condensers, intercoolers, oil and transmission coolers also benefit when the fan is properly positioned.

• Fits many Chevy, GMC, Cadillac, Pontiac, Buick, Ford engine swaps
• Compatible with engine sizes listed in OE-fitment-style applications
• Works for radiator, A/C, intercooler, oil and transmission cooling
• Great for classic cars, hot rods, and tight-modification projects

Who is this for: The Fekuar 6 Inch Slim 650CFM fan is for car enthusiasts, restorers, and custom builders who need a powerful yet shallow electric fan for constrained engine bays. It's particularly useful on classic American V6/V8 projects, hot rods, and any vehicle requiring improved cooling where full-depth fans won't fit. Choose this unit when you want a push/pull-capable, high-flow solution that keeps space for engine modifications while supporting radiator, A/C, and auxiliary cooler performance.
