Review on Enhanced Motorcraft BT-50 Belt Tensioner for Improved Performance by Christopher Bates

Extremely disappointed with Motorcraft parts lately. Your OEM serpentine belt was damaged and now this tensioner is out of alignment after only 6,000 miles. squeaks on the flat side of the belt because the smooth belt pulley is deflected axially. I'll probably try a Gates tensioner, although I haven't been too keen on Gates lately (problems with ill-fitting hoses). Too many companies "outsource" from one country to another and eventually their QC ceases to exist.
