Product Details

Stant Oil Filler Cap 10087 is engineered as an OE-style replacement for the original engine oil filler cap. The cam-on design and rubber seal help restore proper closure at the oil breather/filler opening, making it a practical choice for maintenance on older Ford and Mercury engines. This part number 10087 is listed for 1979 and 1986 Ford Mustang, 1985-1986 Ford Thunderbird, 1981-1985 Ford Escort, 1984-1985 Mercury Cougar, 1981-1985 Mercury Lynx, 1984 Mercury Capri, and 1982-1983 Mercury LN7. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Loose or missing oil filler cap
• Worn rubber seal at the filler opening
• Oil vapor escape from a damaged cap
• Incorrect fit from a non-OE replacement cap
• Restoration needs on older Ford and Mercury engines

Installation Notes and Tips

Verify the cap style and opening shape against the original part before installation. Clean the filler neck or breather opening so the rubber seal can seat properly.
