    The Gates 31066 oil & lubrication components for the 1997-2002 Jeep Wrangler 2.5L and other vehicles is a twist-lock engine oil filler cap that closes the engine's oil filler opening.

    • Steel and rubber construction for a long service life
    • Meets or exceeds OEM specs in fit, form and performance
    • Special finish resists corrosion and protects against high under-hood temperatures
    • OE Exact grade

    Oil residue around the cap or a seal that looks cracked or flattened can mean the cap is worn, though a leaking valve cover gasket or a clogged PCV valve can leave oil there too, so find the cause before you replace the cap. The fitment calls for one cap per engine.

    It also fits the 1987-2002 Dodge Dakota 2.2L / 2.5L / 3.9L / 5.2L and the 1991-1997 Jeep Cherokee 2.5L. If your vehicle isn't named here, look it up by year and engine in the "Vehicles it fits" section.
