NC928S4

I'm replacing the flexible pipe(928 603 143 01) that serves A/C outside temp info and the alternator cooling but don't know the correct routing and geometry of how the piping runs from the ventilation cowl on the alternator up to the A/C Outer sensor behind the left headlight.

The PO basically just coiled the piping up and tie wrapped it in multiple places. I also have a new retaining bar for the piping to install but am not sure where it gets mounted because there isn't one in place now.

I'm looking in PET and see all the pieces but haven't found a picture of the full assembly installed. Thanks for any tips.

I would suggest you ignore what the factory did (it was complete crap) and do better.

Get the "UU" hose holder clamp and create a way to fix this directly to the fender brace on the front side opposite where the splash shield attaches. The stock mount is to the splash shield which is completely stupid - its awkward for removal/installation at best - and actually increases the liklihood of damage to the splash shield AND to the hose mount. The hose feeds laterally through the hole below the ABS hydraulic unit direct into the engine compartment and straight back to the alternator.

What is the length and size we need for that installation?

You need 48” pieces, 36” goes from alternator to sensor, the rest makes the”U”.
