2009 Mercury Mariner Alternator Parts Questions & Experts Answers

• Q: How to service the alternator on a 2.5L generator on 2009 Mercury Mariner?

  A: Service operations for the alternator of a 2.5L generator must begin with a vehicle in NEUTRAL mode while it is situated on a hoist. Begin by disconnecting the battery followed by removing the five bolts and pushpin alongside the RH lower splash shield. Twist the front end accessory drive belt tensioner to set the accessory drive belt on the aside position. Start by taking off the battery harness locator from the generator stud at the lower position before removing the generator bolt and the 2 generator stud nuts. The top part of the vehicle requires a locking tab press to free the generator lower air duct before its removal. The B+ terminal nut of the generator needs removal before disconnecting the electrical connector and generator B+ cable while setting the B+ protective cover and generator aside. To proceed with the generator upper air duct removal process you must take out the three securing screws. Secure the generator upper air duct to its position using the 3 screws before tightening them to 4 Nm (35 lb-in). Place the generator device into position from the top before tightening its nuts on the generator studs by hand. Safely reposition the generator B+ cable and fasten the B+ terminal nut at 12 Nm (106 lb-in) before reinstating both the power supply connection and applying the generator B+ protective cover onto the B+ terminal. From beneath the vehicle begin by tightening the lower generator bolt using hand strength first before securing both generator stud nuts to 47 Nm (35 lb-ft). The generator air duct needs installation alongside tightening of the generator bolt to 47 Nm (35 lb-ft). The front end accessory drive belt tensioner should be turned clockwise to move the belt onto correct pulleys while you install all 5 bolts along with the pushpin and right-hand lower splash shield and torque them to 8 Nm (71 lb-in). Attach the harness locator to the generator stud and connect the battery before finishing the procedure.
