Serpentine Belt Replacement on a Porsche 981 GT4 with the 3.8L engine.
The biggest issue with this job is the 1 mount bracket bolt and spacer you have to remove to do the belt. If your not careful you can drop bolt and then you have to go hunting and lower the engine belly pan to retrieve them.
Removing the interior to access the belt wasn't terrible just time consuming. The whole job probably takes about 3-4 hours to complete from start to finish.
