Q: How do you remove Canister Purge Valves and Vapor Canister on Chevrolet Avalanche,Silverado,Suburban,Tahoe,GMC Sierra,Yukon,Yukon Denali and Yukon XL?
A: To remove the EVAP canister purge solenoid on a V6 model, start by removing the air intake duct and disconnecting the electrical connector and EVAP purge line quick-connect fitting from the solenoid. Then, remove the mounting nut and the solenoid itself. For a V8 model, follow the same steps but also cap both EVAP purge lines before disconnecting the inlet purge line quick-connect fitting. To remove the EVAP canister vent solenoid, disconnect the electrical connector and quick-connect fittings from the solenoid and remove it from its mounting bracket. To remove the EVAP canister, label and disconnect all EVAP hoses connected to it, remove the mounting nut, and remove the canister from its bracket. Finally, to remove the fuel tank pressure sensor, remove the fuel tank and the sensor from the fuel pump/fuel level sending unit mounting flange. Installation for all components is the reverse of removal.
