Alternator, cooling boot ? Options

[luskesq]

I’m replacing the alternator in my ’70 1.7 teener. The cooling boot/vent whatever it is called was missing (99.9% of it). I located an alternator air exhaust elbow on-line that I think attaches to the port on the back of the alternator but I’m not certain where the other end goes. There doesn’t appear to be a place for it to attach to. This elbow is only about 3.5-3” overall so either it isn’t the right part or I’m missing something, figuratively and literally such as more tin. There is a small port slightly below the alt. pivot bolt area coming out of the fan housing. It has a rectangular opening of about 2” x ¾” but for all I know that is part of the heating system and the elbow I have won’t stretch that far.
Would anyone have a picture of what this “boot” is supposed to look like and how it hooks up? Comments & pics are much appreciated.

They are still available nw, check VW online sites, I can't remeber whihc one I used, the difference in the boots, as stated above is one is for the 70 amp alt. and the other for the 55 amp.. one is semi oval and the other round for the alternator end abut the other end for the fan housing is the same round..

Careful using online VW stores for 914 part number reference! Porsche parts catalog as well as Pelican Parts actually list 3 hoses-
021.903.655 1970-71 1.7
021.903.655B 1972+ certain engine numbers, presumably 1.7?
021.903.655D 914 1.8/2.0

A bit hard to decipher the applicability...

It also shows two different size circlips at the fan housing end, 44.5mm and 50.5mm that have the same applicability as the B and D versions, though the two circlips have the same part number! I suspect the larger one will work find in the smaller hose.

So I still think there are differences by engine and model year at the fan housing end!
