Q: How to Service and Repair the Vapor Canister on Mercury Mariner?
A: Service and repair procedures for Evaporative Emission Control Canister require the use of a hoisted vehicle set to NEUTRAL position. First disconnect the battery negative terminal cable to eliminate possible electric danger risks. The EVAP canister electrical connector should be separated first before detaching both fresh air tube and fuel vapor tube assembly from the canister with quick connect couplers. Rework the fuel vapor tube by using its quick connection to remove the purge tube from the assembly. To remove the EVAP canister assembly unfasten its two nuts and two bolts. Follow the removal steps in reverse order while tightening new canister fasteners at 7 Nm (62 lb-in). Execute the Evaporative Emission System Leak Test upon finishing the setup to validate the system functions correctly.
Q: How to Service the Vapor Canister on Mercury Cougar?
A: The service of the evaporative emission control canister starts with disconnecting the battery cable ground before vehicle lifting. The first step involves taking away the ventilation hose from its retaining clips followed by loosening the rear bolts of the evaporative emission canister carrier. Unbolt the front connector of the carrier before lowering the canister alongside the carrier component partially. Disconnect the vent solenoid electrical connector from the canister while also removing the vapor tube connector from the same point. The complete installation process starts with taking out the assembly of evaporative emission canister carrier before disconnecting the vent solenoid from the canister to remove it. Finish the operation by moving the carrier from the canister. To install the system follow the steps of removal in reverse order.
Q: How to Ensure Proper Functioning of the Vapor Canister in a Mercury Grand Marquis?
A: A battery disconnect should be the first step when servicing the Evaporative Emission Control Canister to prevent explosions or fires caused by fuel vapor accumulation. Lift up the vehicle while sustaining it before taking apart both the canister vent solenoid hose assembly and the fuel vapor hose assembly. Remove the Evaporative Emissions (EVAP) canister with bracket assembly through the process of unbolted components and unthreaded nuts. The EVAP canister service requires disconnecting the fuel vapor hose assembly elbow at the canister followed by extracting the canister vent solenoid from its position on the canister before extracting the EVAP canister. Reinstall the parts in the reverse order of removal while conducting a system leak test before performing the evaporative emission repair verification drive cycle.
