Q: How do I remove the EVAP canister purge solenoid and Canister for Chevrolet Cobalt,HHR and Saturn ION?
A: To remove the EVAP canister purge solenoid, turn off the ignition and locate the solenoid. Disconnect the electrical connector and purge line fittings, and cap the lines. Remove the mounting bracket bolt and separate the solenoid. For the vent solenoid, raise the vehicle's rear and disconnect the electrical connector. Remove the mounting bolt, lower the canister, and rotate the solenoid counterclockwise to remove. To remove the EVAP canister, disconnect the hoses. For the fuel tank pressure sensor, raise the vehicle, remove the fuel tank, and disconnect the sensor's electrical connector. Pry under the sensor to remove it. Installation is the reverse of removal.
