Does anyone has instruction how to how to change Serpentine Belt for Panamera V8? Is it easy to do it? Thanks

 

Spend $198.00 for a new belt, that does not include labor.
meanwhile Porsche is finally doing the internal bolt replacing on the recall for all V-8 Porsche's, therefore my belt had to come off, but the cost of the belt not included.

 

My dealer is charging $380 plus tax for belt replacement.

check fitment for your exact model but an OEM Contitech belt (which I ve used before) is about $80.... Do a DIY computer search. You may need to buy a $5 tool too.
I did it on my 911 which took a while because of location but it a DIY project for sure.

 

I haven t looked at the Panamera setup but basically you turn the tensioner nut and it moves that pully back which allows room to remove belt. Same in reverse to put on. Take a pic or draw diagram of belt route before you remove.
I can take a look at mine if needed.

 

yes, I just replaced serpentine belt on my 2012 Panamera turbo (v8). and it wasn't easy: never having done this before, it took 4 hours:: remove air plenum from the throttle body and remove the 2 coolant hoses in the vicinity; this provides barely enough access, but its easier if another 1" air line is removed (not sure what its for); that line releases from front manifold area by pressing in the knurled portions of the plastic ring that surrounds the connection to the manifold; while pressing the knurled areas, pull the pipe towards the front of the car; this pipe, once disconnected, can be rotated or bended out of the way, but be careful! - air and vacuum lines in this area are quite brittle and they snap easily; one additional line that should be disconnected on my car is a 1/4" vacuum line; this line winds it way down the front of the engine very close to pulleys and the belt; there is a "squeeze and pull" connector about 4" after the line turns downward that, once disconnected, makes belt threading easier; also, once new belt is installed, this line can be reconnected such that it positions on the radiator, or front-side (front-side of the car) of the belt, and can be zip-tied safely away from the belt and pulleys;

to loosen the belt, the yoke or fulcrum at the pivot point of the belt tensioner idler pulley must be rotated clockwise; doing so compresses the tensioner spring assembly which pushes the idler pulley towards the drivers side of the car thus lessening tension on the belt; the yoke, or fulcrum has 2 flats, 180 degrees apart, that can be reached and grasped using a 1 and 3/16" open wrench (yes its a large wrench, maybe a large adjustable would also work); I have seen postings on-line that suggest using an torx50 on the bolt in the middle of the fulcrum to try rotating the yoke clockwise - this is wrong!: the bolt simply secures the pivot point for the fulcrum to the engine; it is the yoke, or frame around this bolt that must be turned; once one sees the aforementioned 2 flats 180 degrees apart, one will realize that the flats are for securing a large open wrench (1 and 3/16") and applying clockwise pressure to release tension on the belt;

threading the belt around all the pulleys is straightforward, but not easy: the access is very tight, and slipping the belt over the lower 2 driver's side pulleys has to be done by feel; I started the threading process with these 2 lower pulleys and finished at the alternator; I used an oem belt purchased from a Porsche dealership because I didn't want any incorrect length issues; I had found the belt from $140 to $210 including shipping online; my local Porsche dealer had the part for $231.00, so I spent a little extra to guarantee a perfect fit ... and such was the case: when I cranked the idler pulley fulcrum to its clockwise extreme using the 1 and 3/16" open wrench, there was enough slack to slip the belt over the alternator pulley (the pulley on the far passenger side). I threaded the belt starting from the lowest driver's side pulley (I think its the power steering pump), and then the next higher pulley and so-on; I will try to add some photos in this post in a few days; meanwhile good luck, go easy, and ask me if you have questions or run into problems.
