alternator, and belt tensioner?
 

Ok, i never replaced an alternator on a mustang, just need to know what tools i need, and also, does the tensioner bracket need to come off?

if so i gotta go to my shop and pick up my extensions, sorry for a stupid question, i can see i need a 9/16 and 5/8 i think.

Just need some normal sockets, extension, and probably some Lubricant to grease i tpu to make it easier to get out. Tensioner doesn't have to come off

Thanx jeff, found out it was easier than i thought, back up and running now.
