What torx bit do I need to remove the alternator?

How do I adjust the belt tensioner? Don't laugh--I've never done it before (Cobra has no accessories; uses V-belts). From what I remember it looking like, I would think that I would adjust the location (angle) of the pulley below and to the driver's side of the a/c pulley.

Last thing--what do I need to change the crank and alternator pulleys?

 

T40 or T45 I believe. You can't "adjust" the belt tensioner, but you can pull it back with a 1/2" drive ratchet. The tensioner adjust itself with a spring to take up the slack of the belt.

Crank pulley you just need a torque wrench, for the alternator pulley you need an impact gun.

 

Cort,

Is this on teh Cobra? If you have the older style Windsor with 'V' belts, you may have the tensioner with the adjustment bolt on an idler instead of the spring-type that is so common today. You almost have to use a belt tension gauge with these since it is so easy to overtension the belts and luch a set of alternator or water pump bearings.

I remember going through reman power steering pumps pretty frequently when these first arrived on the scene. Gotta love those cheap-*** Bendix pumps on the old Fords...

If this is on the 'F' car, your alternator sheave may be pressed in place or keyed and held with a nut. An impact may work as Rezinn proposed, or a box wrench and strap wrench on the sheave to prevent it from turning may work. You may end up renting/acquiring a puller to remove the sheave.
He's got the rest covered, too

 

No no no, I should have been more clear. I need to know what size torx bit I need to remove the alt and adjust the tensioner on the formula in my sig. For some reason that seemed clearer to me at the time of the original post , I decided to say that I hadn't had to mess with the type of tensioner that is on my formula when I did the Cobra's belts. I should really learn to stay on topic.

Edit: I read your post Vader and put up this reply. I just read Rezinn's post and now you see how much I know about the belt tensioner . Thanks for the replies. I'll definitely try the T45 (I know it's inside the car somewhere (again, ), but it sure looked bigger than T45. (I may need the embarrasment face again for that last part!)

BTW, it is the older style 351--I had the engine built and I believe I remember hearing that it is a mid 70's block. For some of the story on that car and motor, check out these posts:

You probably even have additional information on this subject, Vader

This has a dumb subject, but I wanted to know (you'll see...) and the part about the Cobra is the reply about 2/3 of the way down on this one

I *just* got in from rebuilding my alternator. My top bolt was a T40 and the bottom one was a T45.
