      Description

      Reliable Coolant Storage. The Coolant Reservoir is a vital component of the engine’s cooling system, storing excess coolant and allowing for expansion as the engine heats up. It helps maintain proper coolant levels, preventing overheating and ensuring optimal engine performance.

      Construction and Appearance. Made from durable plastic, this reservoir is built to last under pressurized conditions and includes a capped opening rated for 20 PSI. Its finish is designed to resist heat and exposure to engine fluids without damage.

      Installation. Installation is straightforward and requires no drilling, allowing for a quick and clean replacement. The part fits easily within the existing engine bay setup for direct mounting.

      Warranty. This product comes with a limited lifetime warranty against manufacturing defects, providing reliable performance over time.

      Application. Specifically designed for the 2020 and 2021 Silverado 2500 HD with a 6.6L V8 gas engine, it offers a direct fit without the need for modifications.
