Mishimoto Ultimate Cooling System Bundle for Ford 7.3L Powerstroke

The Mishimoto Ultimate Cooling System Bundle is a complete cooling system upgrade for the Ford 7.3L Powerstroke diesel. It replaces the components that fail most often with stronger aluminum and silicone parts. It suits trucks that tow, haul heavy loads, or run in extreme heat. Each bundle covers the engine and the transmission cooling circuit.

Bundle Components:

• Aluminum radiator: Full aluminum construction with TIG-welded end tanks and a two-row, brazed-aluminum core for more fluid capacity and better heat dissipation.
• Silicone radiator hose kit: Blue hoses made from 4-ply silicone with embedded heat-resistant fibers, built to handle high temperatures and pressure.
• High- and low-temperature thermostats: The high-temp unit opens later than stock for faster warm-up. The low-temp unit opens earlier for more efficient cooling.
• Aluminum degas bottle: TIG-welded aluminum replaces the brittle factory plastic tank and holds 43 percent more coolant than stock.
• Transmission cooler: Direct-fit design with a stacked-plate core, shown by Mishimoto to lower transmission fluid temperature by about 10°F (5.6°C).
• Supporting hardware: Includes a magnetic radiator drain plug and transmission cooler adapters.
