Product Description

The Mishimoto MMRT-CAWBK Coolant Reservoir Tank is a premium aluminum replacement for the factory plastic coolant overflow tank on select Ford F-250 Super Duty trucks. Designed for both improved durability and enhanced under-hood appearance, this wrinkle black reservoir offers a substantial capacity increase over stock while maintaining a direct-fit installation. With its TIG-welded 6061 aluminum body and robust hardware, the reservoir resists corrosion and handles repeated thermal cycling with confidence.

This complete kit includes everything needed for installation - from the mounting bracket to the reinforced hose - for a seamless swap in 1999-2003 Ford F-250 Super Duty XL, XLT, and Lariat models. Whether you're refreshing an aging cooling system or modifying your engine bay for a cleaner look, the MMRT-CAWBK provides both functional performance and aesthetic appeal.
