Description
The Mishimoto MMCPKG-MUS-67 Cooling Package bundles a 3-row brazed aluminum radiator, an aluminum fan shroud with a high-flow 16-inch electric fan, and a digitally calibrated thermostat into a single, easy-to-order upgrade for classic Ford Mustang and Mercury Cougar owners. Built with an all-aluminum core and cast aluminum end tanks, this Mishimoto cooling system is engineered to keep pace with everything from weekend cruising to drag strip runs.
Instead of piecing together a radiator, shroud, and thermostat separately, this Mishimoto cooling package delivers a matched system designed to work together. The radiator’s tube-and-fin aluminum core and internal transmission oil cooler help manage both coolant and transmission fluid temperatures, while the included 16-inch Mishimoto slim electric fan replaces the failure-prone factory mechanical fan and moves over 1850 CFM of air through the core. The Mishimoto thermostat opens at 180°F, well below the 195°F activation point of a standard thermostat, so coolant starts circulating through the engine sooner and helps keep temperatures in check. Every component in this cooling package is backed by the Mishimoto Lifetime Warranty.
Vehicle Applications
This Mishimoto cooling package is built for the 1967-1968 Ford Mustang and the 1967-1968 Mercury Cougar. Owners of these classic Ford and Mercury platforms can drop in this matched radiator, fan shroud, and thermostat combination as a direct cooling system upgrade over the aging factory setup.
