Detailed Description

This Dorman oil filler cap is engineered to replace the original cap on a wide range of Ford F-250 Super Duty, Ford Explorer, Ford Mustang, Lincoln Town Car, and Mercury Grand Marquis applications. It is designed for vehicles that use a screw-in style engine oil filler cap, helping restore the proper seal at the valve cover or oil fill opening. Dorman 90005 is a practical replacement when the original cap is cracked, missing, loose, or no longer sealing correctly. This part cross-references Anchor 10117 and EC743 for the same application.

What It Helps Solve

• Oil cap missing or damaged on the engine oil fill opening
• Loose or worn threads that no longer hold the cap securely

• Contamination entering the engine through an unsealed oil fill point
• Fitment issues on screw-on oil cap applications in Ford, Lincoln, and Mercury vehicles

Installation Notes and Tips

Confirm application details for your specific Ford Ranger, Ford Expedition, or Mercury Mountaineer before installation. Dorman 90005 installs in the original location without requiring dipstick integration.
