Dorman Engine Coolant Recovery Reservoir Tank

The Dorman engine coolant recovery reservoir tank, also called a coolant overflow tank, coolant expansion tank or antifreeze reservoir, holds the coolant that expands out of the cooling system as the engine heats up. It returns that coolant to the system as the engine cools. This helps keep the coolant level stable, limits air from entering the system and supports reliable engine temperature control.

Key Features:

• Replaces a cracked, leaking, discolored or warped reservoir
• Made from durable, heat-resistant plastic designed to handle repeated heating and cooling cycles
• Molded to match the form and function of the original part for a straightforward replacement
• Includes the molded fill-level markings and connection points required for proper cooling system operation, as designed for each part number
• Engineered to hold up to pressure, heat and engine coolant exposure

Plastic coolant tanks can become brittle over time and may crack or leak after years of heat exposure. Replacing an aging reservoir helps protect the engine from coolant loss and overheating. Dorman is a long-time supplier of aftermarket replacement parts and offers this line of coolant reservoirs for a wide range of applications.
