YzusGomumu Engine Coolant Reservoir Tank with Cap — Direct-Fit for 2010–2019 Chevrolet/GM Vehicles, Corrosion-Resistant

YzusGomumu Engine Coolant Reservoir Tank with cap is a direct-fit replacement overflow reservoir designed to store excess engine coolant and maintain stable operating temperatures for compatible 2010–2019 Chevrolet and GM vehicles.

This replacement coolant overflow tank is engineered as a durable, corrosion-resistant reservoir for specific Buick, Cadillac and Chevrolet models from 2010 through 2019. It arrives ready to install and includes the matching cap, offering a practical fix for cracked or leaking original tanks. Built from sturdier materials than many aftermarket options, it helps preserve the cooling system’s pressure balance and reduces the chance of coolant loss while preserving OEM-style fitment.

How will this reservoir tank improve my car’s cooling system?

By capturing surplus coolant when the engine warms and returning it when the system cools, the reservoir supports consistent coolant levels and pressure. A functional overflow tank prevents air pockets and reduces the risk of engine overheating due to coolant loss.

• Stores excess coolant during thermal expansion.
• Returns coolant to the radiator as engine temperature drops.
• Helps maintain the cooling system’s correct pressure.
• Limits the chances of leaks common in brittle, aging OEM tanks.
