Mercury Mariner Parts Questions & Answers

• Steering Wheel
  BL8Z-3600-UA
  Q: How to service and repair the steering wheel on Mercury Mariner?

  A: Starting your repair and service of the steering wheel requires the removal of the driver air bag module first. Start by disconnecting the steering wheel switch electrical connector from the Clock Spring and conductively separate the wiring from its retainers while placing wires aside. The steering wheel bolt needs removal while users must apply 40 Nm (30 lb-ft) torque when reinstalling it. When using the Steering Wheel Puller to remove the steering wheel avoid both the wires and connector of the steering wheel switch. The project requires taping down the center rotor of the Clock Spring to stop its rotating motion. The installation process ends when performing the opposite steps used during removal.
• Alternator
  AU2Z-10V346-BZRM
  Q: How to service the alternator on Mercury Mariner?

  A: Begin servicing the alternator after positioning the vehicle on a hoist which is in NEUTRAL gear. First disconnect the battery after you remove the five bolts holding the RH lower splash shield with a torque of 8 Nm (71 lb-in). Move the accessory drive belt to the side through clockwise rotation of the front end accessory drive belt tensioner. Release the generator lower air duct by depressing its locking tab then remove it followed by removing the two battery harness locators and the heated oxygen sensor (HO2S) harness locator from the generator shield. Before generator B+ protective cover removal you should disconnect the generator B+ terminal nut which needs to be tightened to 12 Nm (9 lb-ft) before installation begins. The generator B+ cable needs to be moved aside before disconnecting the generator electrical connector. Reinstall the generator shield nuts with a torque of 20 Nm (15 lb-ft) after installation. First remove the pin-type retainer which is located at the bottom of the generator shield and then desynchronize the generator shield. Once the generator bolt is removed you should retighten it to 47 Nm (35 lb-ft) before proceeding with the removal of the 2 generator stud nuts that need to be tightened to 47 Nm (35 lb-ft) during reinstallation. The 2 generator studs should be tightened to 25 Nm (18 lb-ft) during reinstallation before the 3 screws securing the generator upper air duct are removed and re-tightened to 4 Nm (35 lb-in). The technician should first lower the vehicle on the hoist before taking out the generator and will reinstall the new generator using the same sequence for removal.
• Catalytic Converter, Rear
  9L8Z-5E212-D
  Q: How to service and repair the catalytic converter on Mercury Mariner?

  A: Service and repair of the catalytic converter should begin by securely hoisting the vehicle into NEUTRAL position. Detach the electrical connector of the Catalyst Monitor Sensor (CMS) only on 2.5L vehicles. One must use hand tools to detach the spring nuts which bind the catalytic converter to the exhaust intermediate pipe/exhaust Y-pipe and the resonator to the muffler using a side-to-side alternation while loosening both 10-mm and 8-mm nuts. The exhaust hangers should be carefully removed and you should discard both gaskets while taking out the catalytic converter and muffler assembly together. Cut the exhaust system for 2.5L as well as 3.0L and 2.5L Hybrid vehicles. Install the exhaust hanger insulators by using the correct specifications and check for any signs of damage before making replacements. Thoroughly clean every surface that will be sealed by the flanges. The service clamp should be fitted onto the catalytic converter section before secure attachment between the converter and muffler sections. Inspect all parts of the exhaust intermediate pipe and exhaust Y-pipe and resonator flange studs for damage then replace stained components. The C-Frame with Screw Installer/Remover should be used to remove damaged 10-mm or 8-mm studs which need replacing while maintaining correct alignment with the knurl grooves. Install the exhaust pipe together with the catalytic converter and the muffler assembly onto its three hangers. The installer should install a new resonator-to-muffler gasket without rotating it while tightening two new 8-mm resonator-to-muffler spring nuts in three stages from 5 Nm (44 lb-in) to 10 Nm (89 lb-in), and finally to 17 Nm (150 lb-in) through alternating tightening. The converter-to-exhaust intermediate/exhaust Y-pipe gasket requires two new 10-mm spring nuts which should be tightened in three specific stages until they reach 5 Nm (44 lb-in), 15 Nm (133 lb-in), and finally 25 Nm (18 lb-ft). The four service clamp nuts should be tightened to reach 47 Nm torque (35 lb-ft torque).
• Bumper Cover
  5E6Z-17D957-ABPTM
  Q: How to service and repair the rear bumper cover on Mercury Mariner?

  A: Start the repair operations for the rear bumper cover by setting tape at two locations: the corners and below the headlamps to protect against paint chipping. Service technicians should handle right-hand outer bumper cover mount on Mariner vehicles near the exhaust pipe by performing complete removal with extreme care to maintain its integrity. The installation process begins with removing two rear bumper cover-to-splash shield bolts which should be torqued to 8 Nm (71 lb-in). Follow this procedure carefully for pin-type retainers on the outer rear bumper cover to avoid damaging the mounts since you must first take out both central and outer pin-type retainers then the six rear bumper cover screws. Follow by removing both liftgate alignment bumper bolts before disconnecting the two liftgate alignment bumpers, reinstall these components to 8 Nm (71 lb-in) torque. Disconnect the parking aid system electrical connector before starting the removal of the rear bumper cover when system equipment is available. Put the bumper cover back by aligning it properly into the bumper slides while performing the reverse steps of removal.
