I've manage to nick the Coolant Expansion Tank to Water Water Pump hose on my S2 (not all the way through so it's not leaking, but enough to make it a weak spot for a failure in the future.) These things are expensive to replace ($78 at Pelican), so I thought I'd repair it.

The most straightforward way to repair a hose like this is to cut it at the damaged spot, the rejoin using a tube and a couple of clamps. I have some copper tubing, but I was worried about the copper reacting electrolytically with the aluminum. I was worried that plastic connector tubing (as used in irrigation systems, for example) might not withstand the heat very well. Any other suggestions?

At the moment I've just put a clamp around the nicked spot to give it a bit of strength when the system is pressurised, but I see this only as a temporary stop-gap repair. Any other ideas anyone might suggest for a repair of this type?

You could use an aluminium pipe.

 

yeah, thanks, if I had a piece of aluminum pipe handy...

have you checked ebay, it's none of those hoses? most hoses are under 20 bucks there

 

I tried the 'bay, but no luck. It's an S2 specific hose (part no. 944.106.217.02), so I don't think there will a huge number on offer.

Even google didn't come up with much. Pelican was the only supplier I could find that listed these as a stocked item (outside of a Porsche dealership, of course).

Mark,

Post a separate thread and ask for a used hose. Many of us have replaced them and have an old hose laying around. If I hadn't left mine behind in the Caribbean, I'd give it to you.

Good luck!
