The Mishimoto MMRC-11-FRD Overflow Reservoir Cap helps the cooling system in your 1999-2016 Ford 7.3L, 6.0L, 6.4L and 6.7L Powerstroke. 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. This cap replaces Ford part# 9C3Z-8101-B or Motorcraft part# RS-527.
Pressure Tolerance: 1.1 Bar / 16 PSI / 110kPa
Ergonomically Designed For Easy Installation and Removal
Includes Mishimoto Lifetime Warranty
