Dorman 603-5120 Heavy Duty Pressurized Coolant Reservoir

The Dorman 603-5120 Heavy Duty Pressurized Coolant Reservoir offers an improved OE FIX solution for International vehicles experiencing coolant reservoir failures. This replacement reservoir addresses a common failure point found in the original equipment design.

Key Features:

• Constructed entirely from clear plastic material for easy coolant level monitoring
• Eliminates the problematic level indicator that causes leaks in OEM reservoirs
• Pressurized design maintains proper cooling system function
• Direct replacement for failed factory coolant reservoirs on select International heavy duty trucks
• Heavy duty construction designed for commercial vehicle applications

This pressurized coolant reservoir is engineered specifically for durability in demanding heavy duty environments. The clear plastic construction allows operators to visually inspect coolant levels without relying on a separate indicator component, improving reliability and reducing potential leak points in the cooling system.
