Detailed Description

Gates part number 31675 is a regular locking fuel cap engineered for vehicles that require a threaded, vacuum-only cap. The cap helps the fuel tank breathe through controlled pressure and vacuum relief while limiting fuel vapor escape. That makes it a practical replacement for aging or damaged caps on applications such as the Toyota Camry, Lexus RX400h, and Hyundai Sonata, as well as many other listed vehicles.

This part cross-references Monroe Shocks & Struts (e.g., 5795) for the same application. If you are replacing a worn cap on a Lexus ES300, Toyota Corolla, or Kia Optima, Gates 31675 provides the correct style and fitment for the listed vehicles.

What It Helps Solve

• Loose, cracked, or missing fuel cap issues
• Fuel vapor leakage from a worn sealing surface
• Check engine light concerns related to cap sealing or tank pressure
• Difficulty maintaining proper fuel tank vacuum and venting
• Security concerns on vehicles that use a locking fuel cap
