Gates Engine Oil Filler Cap P/N:31115
Gates 31103 oil & lubrication components for the 1999-2012 Chevrolet Silverado 1500 and other vehicles supply an engine oil filler cap, which closes the oil filler opening on the engine.
A cracked or warped cap, or oil seeping around the filler opening, can mean the cap no longer seals, though a leaking valve cover gasket or a PCV system problem can show similar signs, so find out which before you replace it.
Fitment also includes the 2008-2012 Chevrolet Equinox and the 1999-2012 GMC Sierra 1500, along with many other vehicles. If your vehicle or engine isn't named here, run it through the "Vehicles it fits" section.
