HSP Factory Replacement Coolant Tank for 2020–2025 Chevrolet / GMC Duramax L5P

Upgrade the look and reliability of your engine bay with the HSP Factory Replacement Coolant Tank for the 2020–2025 Duramax L5P. The factory plastic coolant reservoir gets the job done, but over time it can become brittle, discolored, and prone to cracking or leaking.

HSP Diesel designed this aluminum replacement tank to eliminate those common failure points while dramatically improving the appearance of your engine bay. Built from CNC cut and bent aluminum and finished with precision welding, this tank is made to last and perform.

With factory-style provisions including a low coolant sensor and radiator cap, this system installs as a direct replacement for a seamless, plug-and-play upgrade.
