Dorman Pressurized Engine Coolant Reservoir Tank

The Dorman pressurized engine coolant reservoir tank, also called a coolant overflow tank, coolant expansion tank or antifreeze recovery tank, is designed to replace a cracked, leaking or worn original reservoir in your vehicle's cooling system. It holds excess coolant as it expands when hot and returns it to the system as the engine cools, which helps maintain proper coolant levels and system pressure.

Key Features:

• Pressurized design that works with the cooling system to help regulate pressure and coolant flow
• Replaces a failed or damaged factory reservoir, a common cause of coolant loss and overheating
• Built from durable, heat-resistant plastic to handle repeated heating and cooling cycles
• Engineered to match the form, fit and function of the original equipment part
• Marked level indicators on many applications make coolant checks easy

Plastic reservoirs can become brittle and crack over time from constant heat exposure. Replacing one promptly helps prevent coolant leaks, low coolant warnings and possible engine overheating. Dorman is a long-established aftermarket supplier known for OE-style replacement parts that help make repairs straightforward.
