Hi, I'm Mike from 1A Auto. I hope this how-to video helps you out, and next time you need parts for your vehicle, think of 1AAuto.com. Thanks.
In this video, we're going to show you how to replace the alternator on this 2005 Ford F150 with the 4.6-liter V8 engine. The items you'll need for this is a new alternator from 1AAuto.com, 1/2" ratchet, a piece of pipe for extra leverage, an 8mm and 10mm socket and ratchet, and a torque wrench.
You want to start off by disconnecting your battery. Just disconnect the negative battery cable, using an 8mm socket and ratchet. Pull the cable free.
Using your screwdriver, just loosen up the hose clamp here and right here. Then push the tab on this hose and pull it free. Then pull your air intake hose free.
Now, using your 1/2" ratchet, just push it into the tensioner. Using a piece of pipe for some extra leverage, just pull the ratchet or breaker bar back and then pull the belt off the alternator. Then carefully release the tension on the ratchet and pull it free. Lift up this harness from that stud and then remove this 10mm nut holding on this harness. Once you remove that nut the harness will pull free.
Now you want to remove these four 10mm bolts. We'll fast-forward as Mike does that. Now push the tab on this harness and disconnect it, and pull that bracket free. Now down here there's two more 10mm bolts holding in the alternator. You just need to loosen them up. We'll fast-forward as Mike loosens those up. Once they're loosened up you can just lift your alternator up and out.
Take your new alternator and feed it down into place. Since our original alternator was working fine we're just reinstalling it. Then you can reconnect the harness and replace that bracket. Then replace those four 10mm bolts and tighten them up. Torque each of those 10mm bolts to 20 foot-pounds. Replace that 10mm nut that holds this harness in place and tighten it up. On this nut you'll see I have a torque wrench in my hand. You don't have to torque this nut. You just want to tighten it up firm but not too tight. Then push that cover back down.
Now tighten up those two lower 10mm bolts. You'll want to torque these to 20 to 25 foot-pounds as well. Take my pipe, pull as far as I can on the tensioner and I should be able to lift the belt up. I'm going to try and take it off of this idler pulley, get it up onto the alternator, pull my tensioner and then push the belt down. You can see the idler pulley is the last one. Push it right down under.
Replace your air intake hose, reconnect this hose, and then tighten up those two hose clamps.
Push your negative battery cable back into place and just tighten it back up.
