• Description:

  This genuine Ford Motorcraft radiator cap, cataloged as an engine coolant reservoir cap with pressure relief, seals the cooling system and maintains the calibrated system pressure that raises the coolant's boiling point and keeps the radiator, reservoir, and heater circuit full and free of air. Its spring-loaded primary valve holds rated pressure during normal operation and vents excess pressure to the recovery bottle, while the vacuum valve draws coolant back as the engine cools, protecting hoses and the radiator from collapse. This Motorcraft cap covers a very broad range of Ford, Lincoln, and Mercury vehicles across many engine families, including 2.0L through 6.8L gasoline engines and 6.0L, 6.4L, 6.7L, and 7.3L diesels, with common applications on F-150 and Super Duty trucks along with numerous cars and SUVs. A worn or weak cap is a frequent cause of overheating, coolant loss, low-coolant warnings, a perpetually low recovery bottle, white deposits around the filler neck, and sweet-smelling steam. Because a cap that cannot hold spec pressure lets the system boil over even when everything else is healthy, replacing it is smart insurance during any cooling-system service. Confirm the filler-neck style and rated pressure for your vehicle against this Motorcraft number before ordering.
