Mishimoto Mishimoto 1.05 Bar GM Overflow Reservoir Cap - MMRC-GM-99

Getting the most out of your performance parts comes down to the details. Your vehicle’s cooling system works best when it’s under pressure. With age and time, your factory coolant reservoir or radiator cap can begin to leak that pressure, resulting in a lower coolant boiling point, reduced cooling system efficiency, loss of coolant, and eventually overheating. The Mishimoto 1.05 Bar Overflow Reservoir Cap for GM vehicles will restore the proper pressure to your vehicle’s cooling system and ensure it operates at peak efficiency for a lifetime to come with our Mishimoto Lifetime Warranty.

• 1.05 bar (1psi) coolant maintains proper cooling system pressure for an efficient cooling system
• Installing a new cap can prevent overheating and cooling system failure
• Ergonomically designed for easy removal and installation
• Mishimoto Lifetime Warranty
