🔧 Fuel Cap - Replacement

The fuel cap on your CR-V is a simple twist-on part that seals the fuel system. If the seal is cracked, the cap won’t tighten, or the check engine light is on for an evaporative leak, replacing the cap is the first thing to try.

Difficulty Level: Beginner | Estimated Time: 0.1-0.2 hours

⚠️ Safety & Precautions

• Work outside or in a well-ventilated area.
• Keep cigarettes, sparks, and open flame away from the fuel filler area.
• Do not over-tighten the new cap; it should click into place.
• If the fuel door or filler neck is damaged, the cap alone may not fix the issue.

✅ After Repair

• Start the vehicle and make sure the fuel door area is secure.
• If the check engine light was on, it may take a few drive cycles to clear on its own.
• If the light stays on after several trips, the leak may be elsewhere in the EVAP system.
