How do you replace the alternator on a 1997 Ford Expedition?

Answer 1

1999 Ford Expedition Eddie Bauer 5.4 http://www.allenengine.com/03-exp-inst.html I recently replaced my alternator (05-28-06) it's not difficult. 1. DISCONNECT YOUR BATTERY. 2. TAKE OFF THE PLASTIC COVER ON TOP OF THE ENGINE. (MINE HAS 5.4 PRINTED ON IT) REMOVE 3 SCREWS. 3. UNSCREWW THE HOSE CLAMP DIRECTLY UNDER THE COVER AND SLIDE OUT THE LARGE HOSE TO GIVE YOU ROOM TO WORK.(DO NOT UNSCREW TO MUCH) 4. UNCLAMP THE TOP RADIATOR HOSE AT THE RADIATOR, MOVE IT TO THE SIDE TO GIVE YU ROOM TO WORK. 5. THERE ARE THREE BOLTS HOLDING THE ALTERNATOR IN PLACE. ONE ON TOP AND TWO N THE BOTTOM. 6. TOOL NEEDED ARE #10 SOCKET TO LOOSEN ALL BOLTS AND A 1/2" TENSION BAR OR A 1/2" SOCKET. (IF YOU USE A SOCKET, YOU WILL NEED SOMETHING THAT WILL GIVE YOU LEVERAGE WHEN YOU PULL THE BACK ON THE PULLEY). 7. THE PULLEY IS LOCATED ON FRONT OF THE MOTOR, LOWER LEFT PULLEY WHEEL. IT HAS A 1/2" SQUARE IN THE CENTER ON IT FOR THE SOCKET. 8. PLACE THE SOCKET IN THE PULLEY AND PULL IT CLOCKWISE. (IT WILL BE HARD AT FIRST) 9. WITH TENSION OFF SLIP THE BELT OFF THE ALTERNATION. (REMEMBER NOT TO TAKE THE BELT COMPLETELY OFF. IF YOU DO, MAKE SURE YOU HAVE A DIAGRAM ON REPLCAING YOUR BELT) THIS ALSO MAYBE A GOOD TIME TO CHECK YOUR BELT FOR DAMAGE. 10. USE THE #10 SOCKET TO REMOVE THE 2 LOWER SCREWS ON THE ALTERNATOR. 11. NEXT REMOVE TE TOP SCREW. AFTER YOU REMOVE THIS SCREW THE ALTERNATOR WILL FALL FREE. BE CARE AND HOLD IT BECAUSE THERE ARE 3 CONNECTION THAT WILL NEED TO BE DISCONNECT. 12. DISCONNECT THE LARGE CONNECTION TO THE RIGHT (pULL STRAIGHT UP), THEN DISCONNECT THE SMALLER CONNECTOR, THIS HAS A LITTLE CLIP THAT SNAPS INTO PLACE TO SECURE IT, I USE A FLAT HEAD SCREW DRIVE TO FLIP IT UP. (IT'S TRICKY BUT DO-ABLE) 13. LAST CONNECTION IS A SCREW. THERE IS A RUBBER COVER OVER THE LAST SCREW, (YES IT'S A #10 SOCKET) REMOVE THE SCREW, BECAREFUL TO SAVE ALL SCREWS JST INCASE YOU DROP ONE, YOU CAN NEVER HAVE ENOUGH SCREWS. 14. SLIDE OUT THE ALTERNATOR WITH CARE. 15. REPLACE WITH NEW ALTERNATOR BY REVERSING THESE INSTRUCTIONS. 16. I HOPE THIS WILL HELP. There is a tensioner just below and to the left of the alternator. You can take a large rachet with out a socket on it and connect it to the side of the tensioner, pull twards you and it should loosen the belt enough for you to slip it off. The tensioner is spring loaded so you have to hold it while you take the belt off. After that remove the two or three bolts and all wires connecting the alternator and it should come right out.
