The location of the EVAP canister purge valve varies depending on the engine type of your vehicle. For instance, the four-cylinder model has the valve at the end of the cylinder head and the V6 models at the rear corner of the engine compartment. The 3.0L V6 model has the valve at the right rear corner while the 3.7L V6 one has the valve at the left rear corner. The first thing you should do is disconnect the cable from the negative battery terminal. For 2011 and earlier V6 models, the lower cowl trim panel needs to be removed, while for 2012 and later models the PCM also needs to be removed. Next, disconnect the electrical connector from canister purge valve and the EVAP line quick-connect fittings. Detach the purge valve along with the mounting bracket as one unit. Then, press the lock tab to slide the valve off the mounting bracket. Installation is the reverse of removal. To a/v canister, again disconnect the negative battery terminal cable, raise the vehicle securely on jackstands, then disconnect the electrical connector and vapor hose quick-connect fitting from the a/v canister vent solenoid. To disconnect the canister, disconnect the two EVAP line quick-connect fittings from it and remove the mounting fasteners securing it. The vent solenoid of the evaporative canister is mounted on the canister. To remove it, release the locking tabs and push the heat shield straight down. To remove the fuel vapor hose, loosen the hose clamp on the vent solenoid. To remove the vent solenoid and dust separator assembly from the canister, release the lock tab. Installation is the reverse of removal.
