• Description:

  This is a genuine Ford coolant expansion tank, Ford catalog names Expansion Tank and Tank Assembly - Radiator, part number 9L3Z-8A080-A, fitting the 2009 through 2010 F-150. Also called the coolant reservoir or degas bottle, this molded tank is a pressurized part of the cooling system that separates air from the coolant, provides a fill point, and manages coolant expansion and contraction as the engine heats and cools. It carries the level markings used to check the system and, on this application, is a sealed pressurized vessel rather than a simple unpressurized overflow bottle. Owners need this part when the tank develops a crack or a seeping seam, when the cap sealing surface is damaged, when coolant is disappearing with no obvious external leak, or when the engine runs hot because trapped air cannot be purged from a failed tank. The plastic becomes brittle with age and heat cycling and often splits along a mold seam or at the neck, leaving a telltale dried coolant residue. Installing the correct Ford tank restores proper system pressurization and reliable coolant level monitoring. Transfer or replace the cap as needed, refill with the correct Ford specification coolant, and bleed the cooling system so no air pockets remain. Inspect the mounting tabs and hoses during installation. Backed by the Ford and Motorcraft parts warranty.

• Applications: 4.6L, 5.4L.
