Keystone Engine Coolant Reservoir Overflow Tank with Cap Replacement

The Keystone engine coolant reservoir, also called a coolant overflow tank, coolant recovery tank or expansion tank, is a replacement part for the engine cooling system. It collects coolant that expands and is pushed out of the radiator as the engine heats up. It then returns that coolant to the system as the engine cools. This helps prevent coolant loss and low coolant levels, and it helps protect the engine from overheating.

Key Features:

• Replacement reservoir designed to take the place of a cracked, leaking, stained or damaged original tank
• Cap included for sealing the reservoir
• Holds excess coolant as it expands, then lets the system draw it back as it cools
• Helps keep the coolant level steady for reliable cooling system operation
• Backed by Keystone Automotive Industries, a known supplier of collision repair and OEM-style replacement parts

A damaged reservoir can leak coolant or lose pressure. Replacing it restores proper coolant recovery and helps protect the radiator, hoses and engine. Choose the individual listing for your application to see its exact specifications and part number.
