Dorman Non-Pressurized Engine Coolant Reservoir Tank

The Dorman non-pressurized engine coolant reservoir tank, also called a coolant overflow tank, expansion tank, or coolant recovery bottle, holds the excess coolant that expands out of the cooling system as the engine heats up. It also returns that coolant to the system as the engine cools. This helps keep coolant at the proper level and supports consistent engine temperatures.

Key Features:

• Non-pressurized design that works as an overflow and recovery container for the cooling system
• Replaces a cracked, leaking, discolored, or damaged factory reservoir
• Molded from durable, heat-resistant and coolant-resistant plastic
• Made to match the form and function of the original part for a straightforward installation
• Translucent construction on many applications, so the coolant level is easy to check
• Many applications include the cap, sensor, or mounting provisions found on the original reservoir

Dorman is a long-established supplier of aftermarket replacement parts. Its engineers design parts to restore original performance and to address common failure points. A new coolant reservoir helps prevent coolant loss, which can lead to overheating. Choose the specific part number for your application from the available variants.
