Keystone Coolant Reservoir Tank with Cap and Hose OEM Replacement

The Keystone coolant reservoir tank (also called a coolant overflow tank, expansion tank, or coolant recovery bottle) is an OEM-style replacement for a cracked, leaking, stained, or worn reservoir. It comes with the cap and hose, so you can restore the cooling system's overflow and recovery function in one step.

Key Features:

• OEM-style replacement design for a factory-type fit and function
• Supplied with cap and hose, as described in the product name
• Holds excess coolant as it expands when hot and returns it to the system as the engine cools
• Helps keep the coolant level stable and reduces the chance of air entering the cooling system
• Backed by Keystone Automotive Industries, a long-established supplier of collision repair and replacement parts

Plastic reservoirs can become brittle, crack, or leak over time because of heat cycling and age. Replacing a damaged tank helps prevent coolant loss and overheating. Select the child item that matches your application to get the right configuration.
