Maintaining proper cooling system pressure is critical for engine longevity, especially during high-stress driving or towing. The Mishimoto 1.1 Bar Overflow Reservoir Cap is designed to replace aging or failing factory caps that often lose pressure over time. When a cap fails to maintain its rated pressure, it lowers the boiling point of your coolant, increasing the risk of overheating and system failure.

By maintaining a consistent 1.1 bar (16 psi), this cap raises the boiling point of your engine coolant, providing a safer and more efficient cooling system. The ergonomic design ensures easy installation and removal, making it a simple but vital upgrade for your cooling loop.

• Increased Boiling Point: 1.1 bar (16 psi) rating provides higher thermal headroom than worn OE caps.
• Direct Fit: Replaces the factory overflow reservoir cap on supported Ford, Lincoln, and Mercury models.
• Ergonomic Grip: Designed for easy removal and installation even in tight engine bays.
• Mishimoto Lifetime Warranty: Built to last and backed by a comprehensive limited lifetime warranty.

• Manufacturer Part Number: MMRC-11-FRD
• Pressure Rating: 1.1 Bar (16 psi)
• Fits Engines: 3.0L
