Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Today, I planned to replace the voltage regulator, alternator actually came out much easier than I thought but on removing, I knocked a hose and it started leaking what I assume is coolant, can I replace just this small section of pipe work or is this worse than it looks.... It's a small hose that leads to the bottom where the alternator sits and loops under the oil filler tube.
Any help appreciated, starting to wish I hadn't bothered trying to do it myself!
The part number is printed on the side of it. looks like 99610622362 or something like that. Get the number from it and google it, or ring your local OPC up and buy one from them.

That's a really common problem on 996 cars at the age they are now. I barely touched mine whilst I was doing the starter and it just snapped. It's an easy fix and a cheap part though. Just be careful when removing the snapped piece from the hose. It can disintegrate into a bunch of small pieces of plastic, which you don't really want to go into the coolant system.
I broke this joiner piece on my car a week ago. I hardly touched it but it disintegrated and a pink jet came out under pressure!
The metal upgrade piece is normally available from Heritage, but at the moment they are out of stock.
I Bought the official part from Porsche and it is under a fiver.
Any 8mm joiner will work but lack the integral body mount bracket onto the head.
I lost over 2 litres of coolant. This hose goes up to cool the AOS. Palaver, but 22 years has made this very brittle.
All good for another 22 years now!
This joiner and the oil fill pipe should probably both be replaced as preventive maintenance, as both will break if they have not been replaced. I did both on mine 5 years ago and I have the joiner saved on my shopping list for my next parts order, just to have a spare.
