  Q: How to replace the canister purge valves on GMC Sierra 3500 Classic?

  A: Begin by cleaning all evap line connections and surrounding areas to avoid contamination before you start replacing the evaporative emission canister purge solenoid valve. You need to take out the air cleaner outlet duct and unplug the evap line quick connect fitting from the evap canister purge solenoid. Begin by removing the connector from the engine wiring harness and then disconnect the chassis evap line quick connect fitting. Remove the solenoid from the Fuel Rail by unclipping its retainer. Install the new evap canister purge solenoid to the Fuel Rail after positioning it correctly and tightening with the retainer. Complete the wiring harness electrical connector connection to the solenoid while also reuniting the solenoid and evap line with chassis quick connect fittings. As the last step install the air cleaner outlet duct into position.
