  Q: How to service and repair the evaporative emission canister purge valve on Mercury Mountaineer?

  A:

  The repair process of the evaporative emission canister purge valve begins with placing the vehicle in neutral gear when you position it on a hoist. Disconnecting the battery ground cable reduces electrical spark generation so that it cannot cause fuel vapor ignition. The combination of potent flammable mixtures in fuel-related parts requires strict avoidance of any smoking activity or fire-related activities. As the first step disconnect the electrical connector from the evaporative emission canister purge valve and remove its two vapor tube fittings. The next step should involve removing the evaporative emission canister purge valve by itself. When putting the evaporative emission canister purge valve back I will first reverse the disassembly order while using clean engine oil to lubricate the vapor tube fittings to make installation easier. A leak test must be conducted on the evaporative emission system and you must perform the evaporative emission repair verification drive cycle to check for proper system operation.
