  1. I have a 66 mustang with a 347 stroker,an aftermarket serpentine setup (march) and i cannot get rid of that annoying squeak...the motor is a late 60s early 70s 302...am I going to need a tensioner for this setup or do I have to find the "perfect tension" via the alternator to get this to stop?the power steering pump doesn't appear to be the problem.. thanks for everything..this site is a marriage saver...i mean money saver
     
  2. Have you already tried spraying it with either belt dressing or 5-56?
