Derale Fluid Cooler with Fan — 12.75 x 9.375 x 4.313 in Black Plate-and-Fin, 6 AN Adapters

Derale Performance Fluid Cooler and Fan is a compact, plate-and-fin aluminum cooler with an integrated fan and 5/8-18 female O-ring ports, built to lower operating fluid temperatures in confined engine bays or auxiliary systems.

This all-aluminum cooler combines a plate-and-fin core with a dedicated fan and 6 AN male adapters to offer a universal, space-efficient oil or transmission fluid cooling solution. Finished in a durable black powder coat, the assembly measures 12.75 x 9.375 x 4.313 inches, ships from the United States, and is supplied ready to mount wherever clearance allows. It’s designed for retrofit and custom installations on vehicles and equipment that need additional heat rejection without a large radiator footprint.

How will this cooler improve my vehicle or equipment cooling?

The Derale plate-and-fin cooler increases fluid surface area and adds forced airflow to accelerate heat transfer away from oil or transmission fluid. By reducing peak fluid temperatures it helps maintain more consistent fluid viscosity and performance during sustained loads. While not a replacement for full radiator systems, it’s an effective supplemental cooler for demanding applications.

• Plate-and-fin core for high heat transfer efficiency in a compact size
• Integrated fan provides active airflow where chassis airflow is limited
• Aluminum construction and black powder coat resist corrosion and reduce weight
• Reduces fluid temperature spikes under heavy or prolonged operation

What are the fittings and connection options for installation?

This unit includes factory 5/8-18 in female O-ring inlet and outlet ports plus supplied 6 AN male adapters for flexible hose routing. The included adapters make it straightforward to connect common fluid lines used for oil, transmission, or power steering cooling loops. Mounting hardware and clearance should be verified against your vehicle’s available space prior to installation.

• 5/8-18 in female O-ring inlet and outlet ports for OEM-style fittings
• Six AN male adapters included for quick hose compatibility
• Universal mounting — fits wherever space permits in engine bay or auxiliary locations
• Compact footprint (12.75 x 9.375 x 4.313 in) for tight spaces

How do I mount and maintain the Derale cooler?

Install the cooler where it receives consistent airflow or mount the fan-facing side to direct air through the plate-and-fin core. Use vibration-resistant fasteners and confirm clearance for hoses and fittings. Routine maintenance is minimal—periodic external cleaning and inspection of fittings and fan electrical connections keeps performance consistent.

• Choose a location with unobstructed airflow or duct to existing fans
• Use proper bracketry and anti-vibration fasteners for secure mounting
• Inspect hoses and adapters for leaks after first run and during service intervals
• Clean fins of debris to preserve airflow and cooling efficiency

Will this cooler work with my specific vehicle or application?

Derale’s unit is offered as a universal cooler, suitable for many oil and transmission cooling needs when the core size and fittings match your system. Verify the 5/8-18 O-ring inlet/outlet and included 6 AN adapters are compatible with your hoses or plan to use adapter fittings. Check mounting space and thermal requirements to confirm this cooler meets your heat rejection goals.

• Universal fit but verify port size and hose compatibility before purchase
• Compact design suits custom installs, hot-rodded vehicles, and auxiliary equipment
• Manufactured in the United States with aluminum construction
• Package weight ~5.6 pounds; lightweight for bracket-mounted installs

Who is this for: The Derale Performance Fluid Cooler and Fan is aimed at DIY mechanics, custom-fabrication shops, and vehicle owners who need a space-saving supplemental cooler for oil, transmission, or hydraulic fluid. It’s ideal when additional heat rejection is required but radiator space is limited—especially in modified, off-road, racing, towing, or industrial applications where dependable, compact cooling is essential.
