Review on Enhanced Motorcraft BT-106 Belt Tensioner by Prettyboy Capers

Worked like a champ trust these parts Motorcraft July 9, 2019 Part failed after 15,000 miles. The tensioner appeared to be locked in its original position and did not tension the old, newly purchased Motorcraft belt that was 10+ years old, now it's 13 years old. I suspect the inner coil spring was rusted before I bought it and 15k broke it. You can shake it and hear it rattle inside. I no longer buy auto parts from Revain. Who knows how old this part was when it was sold to me.
