Why upgrade

The Mishimoto 1964-1966 Mustang Aluminum Radiator w/ 289 V8 is the ideal upgrade to the stock Mustang radiator. Designed and specifically engineered to maximize cooling efficiency, boost engine functions and protect your car from overheating. A stock radiator cannot handle the heat that comes along with having a great deal of horsepower. Mishimoto engineers these kits around real chassis packaging, so hoses, coolers and adapters line up without fabrication on the listed years. Follow the published torque specs and install guide, reuse sensors where instructed, and confirm clearances if you run other supporting mods. Every unit ships with the Mishimoto Lifetime Warranty for as long as you own it.

Features

• Two-row, 1.57-inch thick efficient brazed aluminum core provides increased fluid capacity and optimal heat dissipation — a direct upgrade over the aged factory unit in the early Mustang.
• Full aluminum construction with TIG-welded end tanks delivers ideal temperature regulation for street and strip use, where the factory radiator falls short under high-output driving.
• 1.3 bar high-pressure radiator cap and Magnetic Drain Plug included — raises the coolant boiling point and captures harmful debris with no additional hardware needed.
• Full aluminum end tanks with TIG-welded construction replace the aged factory components that corrode and crack after decades of heat cycling.
• Two-row brazed aluminum core efficiently transfers heat into the airstream, keeping 289ci V8 temperatures stable on the street and strip.
• Confirmed direct fit for the 1964-1966 Ford Mustang with 289ci V8 — no cutting, fabricating, or adapter work required.
• Efficient temperature regulation handles stock and modified 289 V8 builds, including upgraded carburetion and performance exhaust setups.
