Motorad ST13 radiator cap for the 1975-1997 Ford F-150 4.9L and other vehicles maintains proper cooling system pressure, and its safety lever vents that pressure before you take the cap off.

  • Safety lever vents coolant pressure before removal
  • Rated at 13 PSI, with indicator markings of 12-16 PSI
  • Has proper relief and vacuum valves
  • Easy installation and removal
  • 100% tested to ensure proper pressure and longevity
  • Meets all OEM specifications

Coolant loss, a swollen or collapsed radiator hose and overheating can mean a cap is no longer holding pressure, but other cooling parts can be behind them, so trace the cause first. With the engine off and cool, look for cracks or hardening on the rubber seal and crusted coolant around the filler neck.

This cap is a direct-fit replacement for the 1975-1997 Ford F-250 (4.9L, 5.0L, 5.8L, 5.9L, 6.4L, 6.6L, 6.9L, 7.3L and 7.5L) and the 1983-1997 Ford Ranger 2.3L, along with many other vehicles. You need one cap per radiator.
