  Q: How to service and repair the evaporative emission canister purge valve on Lincoln LS?

  A:

  The first step for servicing and repairing the evaporative emission canister purge valve involves disconnecting the battery ground cable to prevent possible fuel vapor ignition from electrical sparks. The service area must stay free of both smoking and open flames as well as personal devices must avoid contact with fuel-related parts because of ignition hazards. The service begins with disconnecting the electrical connector from the EVAP canister purge valve along with removing the upper fuel vapor tube. The two nuts connecting the EVAP canister purge valve bracket need removal before tightening them to 27 Nm (20 lb-ft) torque during reinstallation. Detach the bracket from the studs then remove the EVAP canister purge valve after disconnecting the lower fuel vapor tube. First reverse all uninstallation steps to reinstall the components. A leak test must follow the installation process along with execution of the evaporative emission repair verification drive cycle for proper system operation.

  Q: What Precautions Should Be Taken with the Canister Purge Valve in the Evaporative Emission System to Prevent Explosion or Fire on Lincoln LS?

  A:

  Evaporative emission system fuel vapor and condensed fuel vapor present an explosion and fire risk, so disconnecting the battery ground cable minimizes electrical spark chances that could ignite fuel vapor or liquid fuel in the area, and users should both avoid smoking and open flames near fuel-related components. The first step for canister purge valve extraction requires disconnecting the battery ground cable. The rear subframe must be taken out when removing the canisters from the system. Match the component removal order according to the illustrations while performing the removal procedures. The fuel Vapor Canister requires removal of the rivet before extracting the canister hardware. The installation procedure involves doing the opposite of removal steps followed by performing a leak test. The proper operation of the system needs verification through completing the evaporative emission repair verification drive cycle.
