Bypass thermactor air pump ?

Ok....I have a 1991 f150 XLR lariat 5.0 with aod trans. The thermactor air pump froze up .. so I got another shorter belt to bypass it..also bypass a/c compressor( it dont work also) so I put the belt on the essentials. ...almost right away it started leaking power steering fluid and it's not charging....had auto zone test alternator and it's fine.....did I do something wrong....are things spinning faster since I bypassed the 2 pulleys....the belts tight so now I'm stuck....help

There are bypass pulley kits for the air pump and a/c compressor, that would have taken care of it so you could reuse the same belt.

What he said. In addition a little bit of Googling most likely would have gotten you part numbers for the air pump and a/c bypass pulleys.
