Dorman Heavy Duty Pressurized Engine Coolant Reservoir

The Dorman Heavy Duty Pressurized Engine Coolant Reservoir line offers replacement coolant reservoirs, also called coolant expansion tanks, overflow tanks or coolant recovery bottles, for heavy duty truck and commercial applications. Each reservoir is engineered and manufactured to match the fit and function of the original part, so it replaces a cracked, leaking or worn reservoir directly.

Key Features:

• Direct replacement design: matches the fit and function of the original part for a straightforward installation.
• Pressurized construction: built to hold coolant under system pressure, as the original reservoir does.
• Durable materials: made from quality materials to withstand underhood heat and engine vibration.
• Cap included: models are supplied with a pressure-rated cap. Cap type, pressure rating, mounting provisions and extras such as level sensors or brackets depend on the specific part number.
• OE-matched engineering: designed to cross-reference to the original equipment part numbers.

Replacing a damaged coolant reservoir promptly helps keep the cooling system holding pressure and coolant level. This helps protect the engine from overheating. Dorman is a trusted name in aftermarket and OE-solution parts, with a long history serving professional technicians and fleet operators.
