Review on Motorcraft BT 70 Belt Tensioner by Danny Porter

100% Genuine Ford Part. This will fix your belt squeak you've been chasing. Remove the top fan shroud which simply snaps open, alternator, top idler pulley and belt. You can access the tensioner without removing anything. You MUST use a 10mm wrench to remove the 2 bolts holding the tensioner. Fish it out and fish back a new one.
