DYI- 997.2 Serpentine Belt change
First I would like to thank all the contributors to this forum and today I am trying to do my part.
I have used bits and pieces from a couple of contributors here and on reenlist
I would like to thank Porsche 605 and Porsche 735 and their posts
In the first picture you will see what you will need
30mm open end wrench (large crescent wrench possible)
small prybar or screwdriver
16mm socket
8” 3/8” extension
torque wrench
I bought my wrench and extension off eBay for less than 25 USD
1- remove license plate (back)
2- remove license plate holder (you do not need to remove the bumper)
3- Remove vacuum regulator to air box (it has a clip and s pushed back, towards the reader of the car, gently!) on the right side of the air box
4- Unplug electronic sensor to air box
5- Remove air box
6- Unplug vacuum
7- Below the pulley you will see a "silver" tube that is the spacer that needs to come out
8- left to it, you see the tensioner
9- Get your super long extension and put a 16 mm socket on it
10-Thread it through the hole in the bumper behind the license plate (that is why we removed the license plate and its holder)
11- you will be able to loosen the spacer. But if you do not have a magnetic socket, add a piece of tissue and tape it to the socket, that will make the bolt "stick"
12- remove the spacer.
13- (not pictured) use your 30 mm wrench and loosen the belt, take it off the tensioner and take it off all the other pulleys.
14- Start from top to bottom and pull from under the car
15- put new belt, start with shaft pulley, then water pump pulley (bottom ones)
16- Put over alternator, pulley on top and compressor
17- pull on tensioner and push belt over the tensioner pulley
18- It should be there and "snug:
19- reassemble.
Leave your old belt in the frunk.

Great write-up!
I just did the same thing. I am concerned about my tensioner though. The tensioner is actually a hydraulic cylinder that is attached below the tensioner pulley assembly. See the attached picture.
When I turned the tensioner pulley assembly, it stayed loose. I had to turn the tensioner assembly back counterclockwise to regain tension. It stayed tight however so I am wondering if the hydraulic cylinder is just really slow acting. I wasn't having any problems before I replaced the belt so maybe this is normal?
Question for you. Did your tensioner immediately regain tension after you released the wrench pressure. Did you have to tighten it up or did it slowly regain tension?
Thanks again.

It was as "fast" as a spring rebound

That photo is worth a thousand words and a good reference for how things look that you can't see very well with the engine in the car. Rep points to you!!

What exactly is the the spacer there for and why does it have to be removed to remove the belt? Does the spacer interfere with the spring loaded tensioner or in the way of removing/replacing the belt?
Thanks,
Al
Thanks,

Also to remove the belt with the spacer in place, you would have to cut the belt, but that doesn't help because you still need to remove it to install a new belt.

Got mine all apart now waiting for ordered belt. Took longer to get belt out after it was off the pulleys than the whole rest of the job. What s the easy way to thread the belt back thru? Theres that shield type thing around the bottom pulley that makes it hard.
Took this time to inspect and clean everything up.
