Keep your heavy-duty cooling system sealed and holding pressure with the Dorman - HD Solutions Engine Coolant Recovery Tank Cap (902-5502). This twist-on cap installs as a direct-fit replacement for many MACK trucks, among them the 2008 MACK CXU L6-10.8L / L6-12.8L, 2008 MACK GU7 L6-10.8L / L6-12.8L and 2008 MACK GU8 L6-10.8L / L6-12.8L (see the "Vehicles it fits" section for the full list).
