Dorman Pressurized Engine Coolant Reservoir

The Dorman pressurized engine coolant reservoir, also called a coolant expansion tank, coolant overflow tank or coolant recovery tank, is a replacement part for the engine cooling system. It holds excess coolant as the engine heats up and expands, and returns it to the system as the engine cools. This helps keep coolant levels stable and supports proper cooling system pressure.

Key Features:

• Pressurized design that works with the cooling system to help maintain proper operating pressure
• Built as a replacement for the original reservoir, to restore correct coolant capacity and flow
• Durable molded construction made to handle repeated heat cycles and coolant exposure
• Replaces a cracked, leaking, discolored or damaged reservoir that can cause coolant loss and overheating
• Many designs include the features needed for installation, such as mounting points, hose connections and sensor provisions, to match the original design

Dorman is a trusted aftermarket brand known for engineered replacement parts that solve common failure points. A new coolant reservoir helps protect the engine from overheating and restores reliable cooling system performance. Select the child item that matches your application to get the correct design.
