Good video. Hard to really show what's going on in such a tight space but you guys did a great job with lighting and trying your best not to get in the way of the camera. I do have a suggestion for what you could use to replace that retention pin instead of a drill bit. Drill bits are very brittle and might snap when being used in this method, especially if someone decided to use a smaller diameter bit than what you used. I would use a nail instead as they are ductile and would bend before breaking, a dime a dozen, and if you accidentally left it in before removing the tensioner, it wouldn't be the end of the world. I'm not familiar with how much force the spring inside the tension arm is applying so take this suggestion for what it is, a thought.

When I took out the lower pulley that was making a sound, probably was the original factory. I bought the pulley and tensioner from FCP - OEM. Fit like glove. The top pulley was leaking some grease also. Ok

@joeblow4795 4 жыл бұрын

You shouldn't need the drillbit. That's why they don't provide a metal rod for your old tensioner. It's meant for you to remove the belt while holding the tensioner with the T60. Once you have the belt off, you can release the T60. They have the new one set for your convenience only. I like your idea because the engine bay is tight. But just saying you don't need the drillbit. You can save the metal rod from the new tensioner for the next job.

@adaml.8300 Жыл бұрын

Agreed, and if you do it this way you can take a lot more tension off the belt… it comes off much easier.

My car currently makes a weird high pitched noise a little that sounds like the tensioner/belt needs to be replaced (I had done this previously at ~65k about 2 years ago. I'm at around 81.5k miles now sounds similar to before when I changed it). What are the normal side effects/tell tell signs that I need to change em. 2. I have a 2013 335i xdrive coupe e92. Anything that I would have to do differently on my specific model? Thanks in advance!

The problem with the old tensioner was that not only did it vibrated more than the new one but it also made bearing noise! When the lettering on the old belt shows fading, then it's time for a new one!
