The first procedure when repairing the Evaporative Emission Control Canister requires disconnecting the battery ground cable to prevent fuel vapor explosions or fires. Proceed with the connector electrical disconnect before removing the clamp and Evaporative Emissions (EVAP) canister purge outlet tube. The next step is to unscrew the bolt which holds the EVAP canister before you extract the canister from the vehicle. Detach the canister vent solenoid before unhooking the EVAP canister elbow when the equipment is present. Installation should follow the opposite order of removal steps while performing an EVAP system leak test before finalizing the process. The vehicle needs to perform the evaporative emission repair verification drive cycle. The proper method involves applying MERPOL(R) O-ring Seal Lubricant as well as equivalent products which maintain Ford specification ESE-M99B144-B while lubricating all evaporative emission O-ring seals.

The first step for repairing or servicing the evaporative emission control canister requires a vehicle in NEUTRAL position with utilization of a hoist. Removing the ground cable from the battery minimizes the possibility of electric sparks that would endanger surrounding fuel vapors. First remove the spare tire before disconnecting the EVAP hose and tube followed by removing the EVAP canister vent solenoid electrical connector with its harness retainer. The maintenance procedure on van or wagon vehicles begins with unscrewing the heat shield bolts followed by the removal of heat shield retaining bolts. Begin by checking that all lower bolts from van or wagon automobiles have already been removed followed by removing the remaining bolts to disconnect the EVAP tube from the EVAP canister. End the process by taking out the EVAP canister from its bracket while treating both O-ring seals with clean engine oil before reinstalling the component through the reverse steps. Users should conduct an evaporative emission system leak test followed by completing the evaporative emission repair verification drive cycle after finishing installation.

Starting the procedure to repair the evaporative emission control canister on vehicles with midship or aft axle fuel tanks requires the vehicle to be set to NEUTRAL position on a hoist. Draining the battery ground cable reduces the possibility of electrical sparks forming. Follow these steps to work on the EVAP canister of midship fuel tank vehicles: start by removing the spare tire and unfastening the spare tire carrier extension tube along with the EVAP canister vent solenoid electrical harness retainer from the spare tire carrier assembly. Start by removing the two EVAP canister assembly bracket bolts then tighten them to 17 Nm (13 lb-ft) upon reinstalling them before moving on to unscrew the four spare tire carrier assembly bolts which should be tightened to 150 Nm (111 lb-ft) when reinstalling. Remove the electrical connector of the EVAP canister vent solenoid while separating the fuel vapor tube from the EVAP canister and the fuel vapor vent tube from the dust separator. After uninstalling the two EVAP canister assembly bolts you should tighten them to 17 Nm (13 lb-ft) before reinstallation. Users should remove four bolts securing the EVAP canister assembly of aft axle fuel tank vehicles while tightening these to 17 Nm (13 lb-ft) during reinstallation and take off clamps from the EVAP canister assembly. Position the EVAP canister bracket assembly on a clean working surface and remove the EVAP canister assembly from its bracket while disconnecting the EVAP filter assembly-to-EVAP canister tube. The installation process finishes with leak testing of the evaporative emission system and execution of a drive cycle for evaporative emissions repair verification.

It is important to lubricate all evaporative emission O-ring seals with MERPOL(R) O-ring Seal Lubricant or an equivalent that meets Ford specification ESE-M99B144-B.

Disconnect the battery ground cable to minimize the risk of explosion or fire due to fuel vapor.

Disconnect the electrical connector if equipped, then remove the clamp and the evaporative emissions (EVAP) canister purge outlet tube.

Remove the outlet elbow, inspecting and installing new O-ring seals as necessary with a twisting and pulling motion for the inlet fitting.

Conduct a leak test of the EVAP system and perform the evaporative emission repair verification drive cycle to ensure proper functionality.

The evaporative emissions system contains fuel vapor and condensed fuel vapor.

Disconnect the fuel pump driver module electrical connector, then remove the four bolts securing the EVAP canister assembly, tightening to 17 Nm (13 lb-ft) upon reinstallation.
