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.



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.

 

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.

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.

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

 

Re the front left splash shield and the alternator hose, see how I fixed the hose in place here:-

Splash shield removal is much easier, and the shield should last a lot longer without the hose load.

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:

 

Thanks for chiming in Ed! Diving into it after dinner.

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

 

Let's hope that it sucks!

 

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.
