Default 91 5.0 Tensioner Bolt

I changed the alternator. That went well. I can't get the belt back on. I was wondering how much do I have the turn the bolt to loosen the tension on the belt? I have been turning for a while but I can't notice any difference yet. If I just have to keep turning, then how tight should it be when I eventually get it back on? I am kinda handy but no where even CLOSE to being a mechanic so simple terms please. Thanks

i'm not to sure what your doing but there is no bolt to loosen. put a socket and breaker bar on the tensioner pulley and pull it up.slip the belt on and let the tensioner back down. it does it for you. everything is bolted solid exept for the tensioner arm with the pulley on the end that presses the belt down.

ok....there is a pully arm next to (to the right when facing) the alternator with a bolt on front. If I wedge a pipe under this pulley, using the alternator wheel as the fulcrum I can get it to lift up but i am not strong enough to get it to go far enough to get the belt on. If I put a socket on this bolt and use a ratchet with a pipe on it as a breaker and push clockwise the bolt turns. Should I be pushing in the opposite direction? I am not understanding what you mean by "pull it up" This thing is mad tight.

Default 91 Tensioner bolt

Ok I think I may understand what you are saying. I also have a 98 mustang GT and there is hole on the front of the tension arm where you can stick a ratchet and by turning, lift it up. However on the 91, there is no hole. There is a bolt. Is there a different way to lift the arm?

It is really simple, that bolt is left thread, you put the rachet and turn it clockwise and it will leave you room to put the belt on, if not then you need a tensioner since the spring is not strong enough. Hope this help.

Put a 18mm socket onto the bolt holding the tensioner puller on. Then turn the ratchet/breaker bar COUNTER clockwise. This will lift the pulley up. Once you slip the belt under release your pull on the ratchet/breaker bar and the pulley will fall back down under spring pressure.
