Hi guys,

Yesterday I was about to remove front wheel well cover (928 504 221 11), when I noticed that there were a couple of things attached to the back side of it. I tried to peak inside, but couldn't see much...

Spoke with Roger today and confirmed that one is a U shaped hose that is held to the back of the cover with a screw.

What is the other item? On my car it's attached to the cover with a white zip tie. I couldn't pull the panel out without first cutting the tie and I figured I'd rather ask here first before doing that.

Any ideas?

Thanks!

Clipped from a guide I wrote related to something else (HID lighting installation):








Also, while you're in there, you might want to replace that often-rotted-out alternator hose.

Perfect! Thanks a lot. Can the alternator cooling hose be easily removed and replaced once wheel well cover is out or is it a bit more involved? Gotta love all these small projects that start to pop up once you decide to replace one small thing...

Do yourself a favor and don't mount it back on the splash shield when you put it back together. Fabricate a new bracket to mount it to the fender cross member that the splash shield attaches to. Mounting this to the splash shield was a stupid idea in the first place - real "B" team work. There is plenty of space to do it properly.

With the correct sized hose its not hard to replce the alternator hose - but of course you do need the car up and the lower engine shield (if you have one) removed to get to the alternator.

This is how I did it....

Yes its a little harder on the earlier fender cross support, but still doable as jp shows - and well worthwhile.

Hi Alan,

Do you happen to have pictures of the bracket you made? My problem is - I don't have private garage, whatever fixes/replacements I do, all need to be done in one set; car must be back on 4 wheels at the end of the day. It would help if I can have everything ready prior to jacking up the car...

Thanks!

How many hoses are attached to the alternator? Looking over at PER, it lists 2 separate hoses:

928 603 143 01 (flexible pipe 320mm)
928 603 143 04 (flexible pipe 900mm)

However there is only 1 on the PET image...

The Porsche hose is about $90 and not very good at all.
We have a much better hose for $24.75.

Ed Scherer

That's probably because there's the short piece that forms the "U" and then the long piece; there's one piece on each side of the tube housing the temperature sensor. See the already-mentioned other post in Roger's thread Alternator Cooling Hose - $24.75 for 6 feet. Most of us (as far as I can tell), get one piece of hose and cut it as appropriate.






... and get the hose from Roger or get something else similar: non-permeable hose that will fare better in the presence of grime and oil.

Thanks, I'm planning to get hose from Roger - was just wondering why PET lists 2 different things there...

My way was to ziptie the hose under the cross support, making a U turn back towards the inside fender (sorry no pic available). Very easy, no brackets needed, just two zipties. Very clean install.

jpitman2

The temp sensor is fitted ~12" in from the end, so the 320mm part is the U shaped part clamped on the shield, and 900mm runs down to the alternator - hence 2 pieces. Pic above sort of hides the sensor with tape, but you can see the lead going under the tape, and the two hose clips holding the hose on the sensor. If you buy ~ 1M you should be able to fit it all.

Assuming you have the 'UU' bracket still - then you really only need one small "L" shaped angle bracket, a drill, 3 bolts and ideally 3 nylock nuts.

Bolt one end of the 'UU' bracket to the existing outboard double support and then locate where the 'L' bracket needs to go to drill the cross member - mount the 'L' bracket and bolt it all together. Really it only takes a few minutes. Really simple - what should have been done in the first place.

I mounted the bracket (as in the picture) with a self tapper - bolt & nylock would be better.
