Installation Procedure


    Object Number: 871828  Size: SH
  1. Install the EVAP vent solenoid to the box on the filler pipe.

  4. Object Number: 871710  Size: SH

    Important: The lid or shield for the EVAP vent solenoid must always be installed. The lid and the solenoid box shield the vent solenoid from water and contaminants. This allows the vent solenoid to function properly.

    Important: Ensure that the vent pipe is properly positioned in the retainer on the fuel filler pipe lower attachment.

  5. Install the vent pipe and molded hose to the quick connect on the EVAP canister vent hose.
  6. Install the vent pipe hose to the EVAP vent solenoid and secure with a clamp.
  7. Connect the EVAP vent solenoid harness connector. Push in the connector until a click is heard and pull back to confirm a position engagement.
  8. Install the left rear inner fender well.
  9. Perform the "Service Bay Test" for the evaporative emission system using a scan tool. This test will verify the integrity of the vapor handling areas of the fuel system.
