PRUNkuar 6-inch Slim Push-Pull Electric Cooling Fans 2-Pack — 650 CFM, Low-Profile Mount Kit

The PRUNkuar 6-inch slim push-pull electric cooling fan kit is a compact, 650 CFM radiator and oil cooler solution designed to boost airflow in tight engine bays.

This dual-pack cooling fan set combines a slim profile, reversible blade direction and a complete mounting kit so you can add forced airflow where space is limited. Built from heat-resistant plastics and rated to 80W per fan, these units aim to move a lot of air (up to 650 CFM) at a maximum 2250 RPM while fitting a wide range of classic and hot rod engines. The package includes brackets and tie straps so you can attach the fans to radiators, oil coolers, intercoolers or transmissions without needing major modifications.

How will these slim fans improve cooling in a crowded engine bay?

Because the fans are only six inches and feature a low-profile housing, they can be mounted where larger fans won’t fit, making them ideal for tight shrouds and classic car setups. They generate strong airflow to help move heat away from the radiator, oil cooler or ancillary systems when natural airflow is insufficient.

• 650 CFM maximum airflow per fan for accelerated heat dissipation
• Slim housing minimizes interference with shrouds and accessories
• Reversible blade and wiring allow push or pull installation
• Includes brackets and tie straps for clamp-style mounting

Can I use these fans on different engines and cooling components?

The PRUNkuar kit is intended to be versatile across many classic and hot rod engines — from small-block V8s to larger displacement mills — and can also support A/C condensers, intercoolers, oil coolers and transmissions. Because mounting is clamp-based rather than custom-bolted, the fans adapt to many radiator and cooler thicknesses.

• Fits a wide range of Chevy, Ford, Pontiac, Buick and other classic engines
• Suitable for radiators, A/C condensers, intercoolers, oil and transmission coolers
• Mounting kit works with different fin densities and cooler surfaces
• Blade and wiring reversible for push or pull configurations

What are the electrical and durability specifications I should know?

Each fan in this dual pack runs at up to 80W with a top speed of 2250 RPM. The construction uses heat-resistant plastic designed for consistent airflow and corrosion resistance, aiming for long service life in under-hood conditions. Starting-temperature controls are not included in the kit, so pairing with a thermostat or relay switch is recommended for automatic operation.

• Rated power: 80W per fan; maximum speed: 2250 RPM
• Maximum airflow: 650 CFM per fan for strong cooling effect
• Durable plastic housing resists heat and corrosion in engine environments
• Works with external relay or temperature controller for automatic activation

How easy is installation and can I reverse the airflow direction?

Installation is straightforward for experienced DIYers: clamp the included brackets to the radiator or cooler, secure with tie straps, and wire the fans into your vehicle’s electrical system. The kit is designed so blades and wiring can be reversed, allowing you to configure the fans as pushers (blowing air through the cooler) or pullers (drawing air through the cooler) depending on your setup.

• Mounting hardware and tie straps included for clamp-style installation
• Blade orientation and wiring reversible for push or pull operation
• Compact profile simplifies fitting in cramped spaces without major mods
• Best used with a relay and temperature trigger for automatic function

Who is this fan kit for? The PRUNkuar 6-inch slim fan kit is targeted at classic car enthusiasts, hot rod builders and anyone who needs high airflow in limited space — including owners of small-block and big-block engines listed in the compatibility notes. It’s a practical choice when stock cooling is marginal or when adding aftermarket coolers where larger fans won't fit. If you plan to automate operation, pair the fans with a proper relay, switch or temperature controller to protect the electrical system and ensure efficient cooling only when needed.
