Prevent overheating problems in your 1986-95 Mustang with this 16psi Stant radiator cap. This radiator cap is designed to add pressure to the cooling system and increase the boiling point of your cooling systm. A faulty radiator cap can cause your car to boil-over at a lower temperature.

Stant SWIV-EL radiator cap design allows the cap to be installed and removed much easier than conventional radiator caps by the shell of the cap rotatating independently from the upper sealing gasket stem and bottom plate. Stant's octagonal shape radiator cap is easier to grip than the round OEM design and is designed to function on open cooling systems and overflow reservoir type systems.
