If you have a bit of noise from the belt from oil on it, a bit of baby powder on the belt will instantly make it quiet.

Anybody got video for this? I'm especially interested in seeing removal of the fan.

I just did this job on my MY 2013 with 88k miles. Ordered all the parts from FCP Euro which was the belt and the tensioner/pulley kit. I initially tried to pull the fan out to give myself more clearance to work but didn't want to mess with trying to figure out why the driver's side of the fan was hanging up. So all the work was done with the fan in place. While it's tight, it is doable. Having some specialty tools also came in handy such as the serpentine belt tool I bought a long time ago which is a long breaker bar style tool that is very thin to allow better access.

The below pics are shots of the old belt and the routing as best I could do. I sketched out the routing on paper and will do a clean drawing later. I know there is a N55 belt routing diagram floating around on the forum somewhere. I'll just do one and put it here.

The below pic is of the tensioner. You'll need a Torx 60 to unload tension to get the belt off. The spot you'll insert the Torx 60 is the red box. To unload tension you have to push to the right towards the driver's side. The green box highlights the bolt which holds the tensioner to the engine block. You have to pop off the plastic cover over the pulley to gain access. Make sure you put your free hand below the pulley as that cover is going to fall down the engine bay. That bolt requires a Torx 50. If you also notice, the ribbing of this pulley. It is not ribbed. It's the rubber/material from the belt over time deposited on the pulley. I make note of this because I thought I got the wrong part when the new one was smooth. Rubbing the surface of the old pulley wiped away the "ribbing". Interesting BMW opted to not make this pulley ribbed.

Here is a pic of the tensioner removed and the area of the block where the tensioner mounts.

Here is a pic of one of the idler pulleys which I replaced with a new one from the kit. It's marked off with the green box. You can see above it I had already installed the new tensioner and I marked off in red the install pin. Again the pulleys have a cover over the bolt which needs to be popped off. The bolts holding the pulleys require the same Torx 50.

Here is a pic of the top idler pulley removed. I marked off where it mounts to the engine block in red. The other idler pulley below the one you just removed is marked off in green.

Here are all the old replaced parts.

Of note, once you get everything bolted on and you're ready to install the belt, pull the install pin out of the tensioner. You won't be able to unload the pulley which applies tension to the belt enough with it in place to get the belt installed.

Forgot to also mention, you need a Torx 20 to unscrew the screws which secures the air intake to the core support. There are 4 of these screws.

Below is the belt routing I made up for the N55. Pulley sizes and location relative to each other and on the engine is not exact.

I install the Belt last week and I did not remove the fan.

There is a video on how to remove the fan from Bavaria I think.

I can tell you that there are 2 clips that are holding the fan from the bottom of the intercooler. I did not discover this when I was doing my OFHG but found it during coolant flush. You have to unclip them before you can pull the fan out.

If you remove the plastic covering under

I figured as much. But I am glad I didn't have to deal with having to pull the fan out regardless. And from what I can tell, the heavy duty fan I have as part of the PPK2 is a bit thicker than the normal 135i fan.

Any tricks to get the service pin out? I have everything set up and for the life of me can not pull that pin out to put tension back on belt. Any help appreciated thanks!

You have to put tension on the tensioner pulley arm where you insert the T60 bit. Push the socket/wrench, breaker bar, etc towards the driver's side. You only need move it a little bit to be able to pull the pin out.

Were you able to load the belt with the pin in? I couldn't. I had to get the pin pulled out as the pin was not allowing me to push the breaker bar enough to get the belt over the last pulley.
