Remove Duratec alternator in an hour
Removing the Duratec Alternator from above
There are a couple of threads about removing the Duratec alternator. Your car should be similar, but I know in the thread that I made, the 07 doesn't have the PS reservoir in the same spot, so that's one less thing to remove.
I will also suggest, as I always do, that you shrug off the temptation to purchase a lifetime warranty alternator from a national chain store, and go and get yours rebuilt locally. There is likely a local rebuilder in your area. All you have to do is ask around at shops, or ask a knowledgeable parts guy who lives in the area. You can also look in the Yellow Pages, but don't be discouraged if you don't find any information online. These businesses are old, and don't require walk-in customers to survive since most of their business is with local repair shops, fleet maintenance, etc.
More than once we've seen where an FF will get a Lifetime warranty alternator, and it will fail within a few months, and so on and so on until they finally search for another rebuilder. We've even seen some people go so far as to pay $300 for a new Motorcraft part to avoid this problem. I had my alternator rebuilt for $80, and it's lasted a year already. That's the difference that local rebuilds will make for you: better quality parts, and lower price, for the cost of a day without the car.
You get to support your local small business too instead of sweatshops in some South American country.
