I dunno, I do change my belt often in my truck as I like to bypass ac an powersteering when I hit the track..it's alot easier doin it topside with the tensioner (at least in my truck) rather than having to jack up a vehicle, remove a belt cover than having to rotate the crank to roll the belt onto the pulleys. And the thing is, my belt was barely frayed, only reason I swapped it out was because I was installing a new ac compressor...and the instructions to remove belt is to cut it, I could have kept it for an emergency backup. And what about if your driving along someplace and the belt does go bad, at least with the tensioner you can change it on the fly... than again, changing a belt in my gmc minivan is a big pain as well...so it goes both way I guess dependent on a respective car/truck.Tensioners are not that easy.
You need a third hand or a tricky way to hold the tensioner while you install the belt.
Just be glad the belt doesn't have to be replaced very often.
Mine had 75k on it and I noticed the serpentine belt was freying. 3 days later it popped while I was in a parking lot. I got the part from rock auto for around $35-45. It comes in a kit.. there are no tensioners, you just cut off the old one and shoe horn/man handle the new one on.. helps to have 2 people. One up time and you under. A long pry bar helps push it onHi everyone, first time poster. Bought my Fiesta Dec 2010. Went today for normal oil change and was told my Sepentine Belt was fraying, which it is. Car has 90k miles on it. Read some posts. Cant find the belt anywhere, even on the Ford Parts Website.. am i doing something wrong? Tried drive belt, serpentine belt etc... Why is this not available in 3rd party parts list either. Mine is a 4dr SES 1.6l standard with air conditioning.
