This was a very helpful video with the main details included (bolt head sizes and torque amounts were a nice touch). The routing of the Serpentine belt seemed more intuitive to me than did the Accessory/Air Conditioning Belt routing did. So, I had to hunt for that routing online, but a quick google found it fast. It was just easier seeing the routing in a still picture. I have a 2014 Ford F-150 4X4 XLT with a 5L V8 engine. My AC belt was starting to chirp any time I turned on the AC and often right when I started my engine. I have 115,000 miles so I figured I would just take care of replacing the parts myself. Here are the parts I changed: - Main Drive Serpentine belt (6 ribs) [Autozone $22.99] - Main Drive Serpentine tensioner [Autozone $103.99] - Accessory/AC belt (4 ribs) [Autozone $22.99] - Accessory/AC Idler Pulley (4 ribs) [Parts Geek $78.43] - Accessory/AC tensioner [Advance Auto Parts $48.75] Below are a few notes/details where my truck differed: - My truck has a 4 rib crankshaft slot for the Accessory/AC belt, so I had order a 4 rib Idler Pulley online. The Serpentine belt slot had 6 ribs. - My new Serpentine belt tensioner had a different mounting bolt which had a 5/16 recessed Allen head (I needed to buy a Socket set that had Allen wrench tips from Auto Zone $26). - I had mounted the Serpentine tensioner onto the truck before I placed the Accessory/AC belt around the Crankshaft but I was still able to get the Accessory/Air Conditioning Belt slide between the crankshaft and the main drive tensioner.

Really helpful video brother! I just needed to replace my drive belt because it was already a bit worn and had 140k miles on it. Local shop wanted $40 and i was supplying the belt. Waited for sunday, watched this video first and decided to tackle it! Got my CAI out of the way, got my ratchet and a 15mm socket and got the belt off and new one on in less than 5 minutes!

Is it 13 or 15 mm for the tensioner?

Do any of these need thread locker? Im about to change them all and I was told they need it..

Thank you! Very helpful, I appreciate it

Great video but having specific part numbers for the 5.0 would be much more helpful. The website doesn’t differentiate between the alternator belt and the AC belt. Nothing for the tensioners either.

How long does it take to replace both belts

But you failed to show the routing of the passenger side.

[@mog_3825]

Routing diagram for drive and passenger side is under the hood. Also, Google
