Automann Engine Coolant Reservoir

Manage coolant expansion safely within your Peterbilt engine bay using the Automann Engine Coolant Reservoir. Designed as a direct-fit surge tank, this Automann 575.1023 captures expanding coolant as system temperatures rise, helping maintain proper pressure balance and consistent radiator performance. The translucent heavy-duty polymer body allows technicians to quickly confirm fluid levels without removing the pressurized cap. Built to withstand continuous exposure to engine heat, the molded housing maintains its shape within Peterbilt-specific chassis configurations. As a practical aftermarket replacement, this assembly restores proper coolant containment when the original reservoir becomes cracked or brittle, preventing leaks that can affect surrounding engine and axle components.
