Mishimoto MMRAD-MUS-79DP Dual Pass 3-Row Radiator for 1979-1993 Fox Body Mustang

Vehicle Fitment

• 1979-1993 Ford Mustang (Fox Body; L, LX, GT, Cobra; 5.0L 302 V8; RWD; Manual Transmission Only)

Fitment Notes

• Manual transmission vehicles only - automatic transmission applications require a standalone transmission cooler (Mishimoto MMTC-U), as this radiator does not include a built-in transmission cooler
• May require longer radiator hoses depending on the engine build and engine bay configuration
• Inlet location: Upper passenger side (1.25"); Outlet location: Lower passenger side (1.5")
• Dual-pass design routes coolant across the upper core on the first pass, then redirects it across the lower core on the second pass for maximum heat extraction without increasing overall radiator size
• Direct-fit for Fox Body Mustang 5.0L - does not fit 4-cylinder or 6-cylinder variants without modification

Features

• Unique dual-pass racing design doubles cooling efficiency by making two coolant passes through the core rather than one
• 3-row aircraft-quality aluminum core with hand-welded TIG construction for race-grade durability
• Brass fittings with dual pressure testing ensure a 100% leak-free installation
• Increases cooling capacity without increasing overall radiator size - ideal for engine bay clearance constraints
• Included 1.3 bar high-pressure radiator cap raises the coolant boiling point for a safer, more efficient system
• Included magnetic drain plug captures metallic debris circulating in the coolant circuit
• Ideal for street, drag strip, and track use on built 5.0L Fox Body applications
• Backed by the Mishimoto Lifetime Warranty

Product Description

The Mishimoto MMRAD-MUS-79DP is a direct-fit dual-pass 3-row aluminum racing radiator engineered for all 1979-1993 Ford Mustang Fox Body models equipped with the 5.0L 302 V8 and a manual transmission. Unlike a conventional single-pass radiator, the dual-pass design routes coolant across the upper half of the core on the first pass, then redirects it across the lower half on a second pass - effectively doubling the heat extraction capacity without requiring a larger overall radiator footprint. Hand-welded from aircraft-quality aluminum with brass fittings and dual pressure-tested for leak-free performance, this radiator is purpose-built for modified, high-output, and track-driven Fox Body builds.

The 3-row core measures 24.45" x 16.7" with a 2.05" core thickness and delivers substantial cooling capacity improvements over the aging stock radiator. The included 1.3 bar high-pressure radiator cap raises the coolant boiling point for enhanced safety under hard driving conditions, and the magnetic drain plug protects the system by capturing metallic particles during coolant changes. Note that longer radiator hoses may be required depending on your specific engine build. No built-in transmission cooler is included - automatic transmission applications require a standalone cooler (MMTC-U). Backed by the Mishimoto Lifetime Warranty, this dual-pass radiator is the serious cooling upgrade for any Fox Body 5.0L Mustang build.
