Mopar® Oil Filler Caps
Order today and find out why Mopar® is every mechanics choice for genuine OEM parts and accessories. Oil filler caps seal your engine's oil filling port while providing convenient access for routine oil changes and level checks. These components must create an airtight seal to maintain proper crankcase pressure while withstanding temperature extremes and chemical exposure from engine oil. Quality caps prevent contamination and oil loss that could damage engine components.
Sealing Technology and Venting Functions
Mopar® oil filler caps feature rubber gaskets and threaded designs that create leak-proof seals while allowing controlled crankcase ventilation. These caps must seal against oil vapor pressure while preventing moisture and debris from entering the engine. Temperature cycling causes cap materials to expand and contract, gradually affecting seal integrity over time. Gasket deterioration can allow oil leaks or vacuum loss that affects engine performance. The air filters work closely with crankcase ventilation systems to ensure proper engine breathing and prevent contamination from reaching internal components.
Replacement Indicators and Service Intervals
Oil filler caps typically last 80,000-120,000 miles before developing seal problems or thread wear that affects proper installation. Warning signs include oil seepage around the cap, difficulty removing or installing the cap, or visible cracking in rubber seals. Caps that won't tighten properly or feel loose after installation should be replaced immediately to prevent oil loss. Missing or damaged caps allow debris to enter the engine and can cause significant internal damage. Popular vehicles like the 300 and Cherokee feature easily accessible oil filler caps that simplify routine maintenance while providing reliable sealing performance.
Why Choose Genuine Mopar® Oil Filler Caps
Genuine Mopar® oil filler caps ensure proper thread pitch and sealing characteristics that maintain correct crankcase pressure compared to generic alternatives that may not fit properly. Our caps use materials specifically designed for oil and heat resistance, providing reliable sealing that protects your engine from contamination.
