Rudy's bundled the Ultimate Mishimoto coolant kit for your 6.4L Powerstroke Diesel.  Keep your engine operating at top notch with all the necessary coolant hoses, thermostats, and coolant!  This kit comes complete with Mishimoto upper and lower radiator hoses, Low temp thermostats, 16 PSI degas bottle cap, and 2 gallons of Motorcraft concentrated Gold coolant.


Mishimoto Cap:  Getting the most out of your performance parts comes down to the details. When faced with hard driving conditions, a vehicle's cooling system becomes highly pressurized. Factory caps are not equipped to handle long term use and often lose pressure, in turn reducing the potential coolant boiling point and boiling the coolant. The Mishimoto 1.1 Bar Overflow Reservoir Cap will keep coolant where it needs to be, flowing within the system.


Mishimoto High Temp Thermostats: The Mishimoto thermostats have a higher activation temperature (198°F/208°F) compared to the factory thermostats (192°F/203°F). The higher activation temperatures restrict coolant flow longer to allow a quicker engine warmup, making these thermostats ideal for use in cold climates. Pair this thermostat set with the Mishimoto 6.4L Powerstroke Performance Aluminum Radiator for a complete cooling system overhaul.


Mishimoto Radiator Hoses:  Mishimoto has developed a silicone hose kit specifically for the 2008–2010 6.4L Powerstroke. Mishimoto Powerstroke coolant hoses are constructed from a combination of high-grade silicone and five layers of heat-resistant embedded fibers to provide the ultimate upgrade in reliability, durability, and performance. The engineers at Mishimoto designed four 6061 aluminum CNC-machined couplers which mate the Powerstroke coolant hoses to either the factory or Mishimoto 6.4 aluminum radiator and include spring clips for a simple install. All of the CNC-machined couplers also feature a double O-ring design to prevent air pockets from entering the cooling system.


Motorcraft Gold Coolant:  Provides year-round antifreeze, anti-boil and corrosion protection.  A 50/50 mixture of this antifreeze/coolant and distilled water provides freeze protection down to -34 °F (-36.7 °C) and boiling protection up to 265 °F (129 °C).  Approved to Ford Specification WSS-M97B51-A1. Use when Ford Specification WSS-M97B51-A1 is specified
Do not mix different colors or types of antifreeze/coolant in your vehicle. Mixing of antifreeze/coolants or using an incorrect antifreeze/coolant may harm the engine (or electric motor) or cooling system components and may not be covered by the vehicle Warranty.  Meets or exceeds the requirements of WSS-M97B51-A1, ASTM D 3306, Chrysler MS-9769, Cummins 14603, and ASTM D 6210.  Contains a bittering agent
