how i did mine. loosened the passenger side motor mount and slid the motor foward. the first time i did it, it was a complete BITCH!! took me and my dad a better part of the day to do it. replaced it again (pos autozone alt crapped out) and did it by myself and only took me 2 hours.Zetec is easy I think, lol.
Best way is to pull the 3 bolts on the P motor mount out and slide the engine forward. That gives you plenty room to get the Alt. out.
*for some reason automatic cars are a tighter fit than manual cars.
Remove the red plastic cover from the alternator stud to remove the positive cable. If you try to remove the 10mm nut on the post you'll break the post (most times). There are 3 tabs bent over holding the nut in place.
If you can slide the engine forward enough you won't need to remove the shield on the fuel line but you will have to move the PS res and coolant tank out of the way.
This. When I did mine I just move the coolant tank, the power steering tank, the evap canister outta the way, and there was JUST enough room to get the alternator out. Its tight, so ya gotta twist it and move it a certain way to get it out. Took me about an hour.It can come straight out in 12 mins with a bunch of turning to find the right way out.
