How to remove the vent valve solenoid tubing?
Disconnect the evaporative emission (EVAP) canister vent electrical connector, if equipped. Disengage the 2 vent valve pipe clips securing the pipe to the underbody. Remove the clips from the underbody and discard. Disconnect the vent valve pipe at the EVAP canister.
When does an EVAP vent solenoid wear out?
Once the solenoid is triggered, air is introduced to the EVAP and relieves pressure on most US and domestic cars, trucks and SUV’s. When the EVAP vent solenoid works correctly, it can last for the life of the vehicle under normal operation. However, there are multiple reasons why the EVAP vent solenoid can wear out prematurely or fail completely.
How does the EVAP purge solenoid work in a car?
Hydrocarbon is distributed by the EVAP purge solenoid into the fuel system and burnt during the combustion process. The filtered hydrocarbons are converted to carbon dioxide and released back into the air by the EVAP vent solenoid. This component is typically in an open position when the vehicle is running and closes when the vehicle is turned off.
How to remove the EVAP pipe from a Silverado?
