BMW 740 540 AC Compressor Belt Tension Pulley Removal 

Please note this is the difficult version. The easiest way to remove and install the belt is to place a 50m Star ratchet in the tension pulley. DO you see the arrow on the "star" bolt? means push down. The shock piston on the pully tensioner compresses and off comes the belt....this process only takes 2 minutes. No need to loosen any nuts at all.....again just compress the piston by pushing the tensioner down...super easy...ALL and ALL enjoy the breakdown of the video

this guy almost NEVER goes wrong really..., I will look if you have vid on water pump pulley, great vid !

Thanks for your video bro. I was having a hard time reinstalling the Drive/alternator/power steering belt after replacing one of the idle pulleys. Your video explained how to release and retighten the idler. You're the man!!!!!

Thanks was working on my car today your videos help alot

How do you change the serpentine belt and tensioner on the alternator side; of this exact engine e39 540i? I would love to see a video on the entire procedure. Thanks for sharing.

perfect illustration. Thanks for the video.

your belt could be causing noise but won't prevent AC compressor from working. If you Blower is not blowing cold air into your interior car, then it could be that your blower is out or a fuse. Many problems can lead to AC issues.

Thank you guys for all your videos, very helpful and very much appreciated .

Hello, please tell me how much pressure do you put on the main belt tensioner (pump,pulley, generator)? if I pull hard, an unpleasant knock appears, bmw m62, I loosen everything well..

Solid video! Thank you!!

I have a 2001 x5 4.4 i think the tensioner is bad for the drive belt I don’t see any pulleys that look loose and the belt is new can I fix the old tensioner or do I need a new one

do you have the torque specs for the vibration damper,? I need to know how tight I need to go on that big center bolt and the bolts that go around.. plus do you have the torque specs for the water pump pulley ?? it be very help ful if you or someone replies ASAP!! thanks

Do you have a video for the drive belt replacement for E39 540i?

are the bolts on both ends of the tensioner shock loose pivot points or are they tight. It seems that they should be loose so they pivot.

thanks for video.My AC comprassor s not working My belt s looking really bad could it be about the belt?

Well done Dude; keep up the good work.

The size of belt..please

Another excellent video. Thanks

Thanks for sharing.. it was very helpful.

Is this the same process used on an e39 M5? Thanks!!

What's the name of the part you have your ratchet on in your video on 1:18 mins please any suggestions would help I need tht part

is the 750 il same prosses

very informative thank you

I have two pullies touching, what do I do about that?

You say it's easy, YES, but as soon as you removed bumper, radiator and headlights lol.

Does anyone have anything on putting a idler pulley & serpentine belt back on E38 740iL BMW Just E38 7series

is the 750 il same prosses

And what about the belt that's in front of the AC belt? we can see on the right pulley that there's a place for another belt.

Should be similar process.

So first take the entire front end off of the car; you failed to mention that small point. Son
