Alternator Cooling Duct Question
I was looking at a picture in the WSM, which is also linked below from a prior thread showing two duct type hoses for the alternator cooling assembly. The first part is the one that completely rots out on us while the second forms the U-shape we see behind the splash guard. Both of these hoses are clamped to the housing where the HVAC temperature sensor inserts into a coupler.
https://rennlist.com/forums/attachme...r-air-hose.jpg I am using Ed Scherer's method of repair, but it looks like Ed used only one hose rather than two, and just cut a slit for the temp sensor to be inserted into the coupler. *I THINK* I have a 6-foot duct at home of some nice oil resistant stuff 2.5" OD. Can't I just slide the coupler in and punch a hole for the sensor to run through? It'd be a shame to cut it into two separate ducts and risk it uncoiling later. http://lh6.ggpht.com/_T5A7537WhI4/TG...0-07-0293a.JPG |
Andy,
Main thing with that hose is that the air flow path should be in good nick. I doubt it makes any difference where the temperature sensor is located as long as it sees the air flow. I assume the U bend is in effect a snorkel to minimise the chances of sucking water into the alternator in the event you go sub aqua. Rgds Fred |
Hey Fred, sorry I should clarify - I'm not trying to relocate the sensor, but rather trying to find out if I have to cut this hose into two parts. Initially, I was just thinking of leaving it as one whole unit and sliding the HVAC sensor coupler through the hose itself, clamp, punch a hole and insert the sensor.

Andy,
Your note was perfectly clear- on mine I just inserted the carrier into the end of the hose rather than mess around cutting the hose into two as it were. Would not appeal to the originality buffs - just saw no point in trying to replicate the stock setup. Rgds Fred |
Ah ok. Thanks Fred! I may do the same thing you did along with the screen mod as a 'just in case'. We have been getting critters at my house lately thanks to neighbors leaving food out :mad:

Re the front left splash shield and the alternator hose, see how I fixed the hose in place here:-
https://rennlist.com/forums/928-forum...placement.html Splash shield removal is much easier, and the shield should last a lot longer without the hose load. jp 83 Euro S AT 57k |
I saw some mounting solutions using the fender's crossmember. I was going to attach it at that point. I just need to find out what size bolt or screw to use in order to do it (M6)??

I cut it. You can even see the shorter of the two pieces in the fourth photo in the thread.
Note the following excerpt from that post:

"Screw" the top hose over the bottom one where they join at the sensor mounting tube so if any water spray gets in there, it'll flow over the joint (and down the sensor wire) rather than into it. https://lh5.ggpht.com/_T5A7537WhI4/T...0-07-0292a.JPG http://lh6.ggpht.com/_T5A7537WhI4/TG...0-07-0293a.JPG |
Thanks for chiming in Ed! Diving into it after dinner. :)

another side benefit of the Greg Brown alternator - cooling hose not required :)

Pretty. :)

Good luck installing that hose onto the back side of the splash shield.
it was a real bitch when I had to access my front side marker for a clear lense upgrade. |
I mounted mine to the fender crossmember. No sweat. Everything is back together already. Time for a drive :D

I would recommend everyone to relocate the hose end mounting WYAIT - the back of the splash shield was VERY STUPID idea in the first place. Porsche doesn't always get it right.
