The Porsche price for the alternator cooling hose is circa $80 for both the long and the short section. After market is about $8 a foot.
I have in stock Gates 2.5" ID defroster hose that works perfectly as a replacement.
Comes in 6' lengths and my price is $24.75. Plenty to replace the hoses and some left over. Black just like the stock hose and rubber impregnated fabric.

928sRus keeping prices down so we can all afford to drive more.

Great Price Roger

I paid $45 for 6ft. at oldcarstuff not so long ago.

Thanks again for the great pricing.

I'll take two.

Every 928 I've seen has either missing or thrashed alt cooling hose. It's critical to keep the alternator cool in the summer when the AC is running. Easy install too. No reason now not to have this restored completely.

I'll take one, as well. I'll call tomorrow and place my order.

Roger,

I don't see how it can be a perfect fit. The Porsche hose is 60mm I.D ( 2.375" ), slightly smaller than your 2.5" I.D. ( 63.5mm ).

Since you can't seem to source the hose in metric dimensions, I wonder how this 60/64mm silicone rubber hose adapter might work?

It works with 2.375" - 2.5" which seems ideal, but the hose is also slightly larger in O.D.

Then, there's this 60mm high temperature silicone hose in the UK on eBay....

For my 90' S4, the PET shows 900mm long for the longer hose, and 320mm for the shorter hose, or 1220mm total length.

Roger,
I see the temp range is -40 to +93. Is this C or F? If F it's not going to work.

Borland,
It's a perfect fit on the cooling shroud. Fits even better than the Porsche hose.
The actual shroud is eliptical and the Porsche hose is very difficult to fit and only fits about 25mm on to the shroud. To push it further would cause it to split as it's that tight.
The aftermarket hose fits tight but will slide off if pulled hard enough. I would recomend a tie wrap.
Again this was not my idea but that of a number of 928 owners that had bought the hose from O'Reilly's for circa $30.
The other hose often used was from oldcarstuff and that is also 2.5"ID and that works well but more expensive.
I was looking for something that fitted. worked well and was relativly cost effective.
I am very happy with the choice.

Temperatures are in C so no issues there.

Thanks for the comments,
Roger

Rick Carter

Great Roger, I'll take one.

ROG100

Rick,
Thanks for the business and the hose will be in the mail tomorrow.
Best,

Let's see; 8.89 pounds limey for 500mm times 3.714 kumquats into 5/9 + 32 somolians = $51.85 for 6 US feet, plus shipping and handling and a long distance relationship.... I think I'll go with the Gates: Roger me one in my closet (don't bother to ship, there is nothing to which to attach it as yet). And no, that isn't dirty even though he is a Brit

ROG100

Donald,
I got really excited when you mention kumquats - I think I remember what that means or it is just a boreing little fruit.

You remember, you sentimental old fool! I'll leave it to Randy (aka "Moonflower") to refresh you...

If you're boring little fruit, you're doing it wrong.

I finally dealt with my disgusting, revolting, rotten, oil spewing, particle scattering, collapsed hose a couple of weeks ago.

As I was just reviewing some of my recent photos, I thought I'd add them here.

The hose I used actually wasn't Roger's (although it would have been hadn't I wanted to cobble together a solution with locally available parts in one evening); Roger's is almost certainly higher quality than what I used. There's one enhancement that I figured I'd share: a screen on the intake side. I'm paranoid about intakes. Intakes need screens or filters. Period.


First, just to show how nasty these hoses can be (especially after soaking up oil):




How much air do you think was flowing through this?:




Some screen wrapped over a 1½" PVC coupler keeps crud (and rodents!) from entering the intake side:




Start reassembling some parts (only the hose used for the "U" part shown here):




... and complete the reassembly. "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.






Yeah, it's not exactly rocket science, but it's pretty satisfying to finally get this taken care of.
