Last year I replaced my tensioner with a Motorcraft tensioner, and I also replace my stretch belt and serpentine belt, 15 months later, my tensioner went bad, ordered a new one from RockAuto Motorcraft as well, because Ford parts Giant would not stand behind Ford's 2-year warranty, because they are not a Ford dealer, but anyways, the part was supposed to be here July 3rd, I tore the car apart, part never arrived, FedEx then said it was going to be here today, here it is 8:00 it's still not here.. I need to get my car on the road.. so I want to get a ride to Advance Auto tomorrow, to get a liten belt tensioner. I understand they are made over in Canada, and also manufacture OEM belt tensioners. What is your opinion on them? I figure they have to probably be better than AutoZone's duralast..
