Coverage and how to read this overview

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.

POST 1 / ORIGINAL POSTEROriginal post

What should I do about this? Is it something I can try address or more serious?

POST 2Original post

Clean it first,  Then you might be able to pin point the location, ie; Hose or pump or both.

POST 3 / ORIGINAL POSTEROriginal post

Tried that but it has stopped (run out of coolant). Can i put water in to try and find it?

POST 4 / ORIGINAL POSTEROriginal post

Does this suggest it’s coming from higher up?

POST 5Original post

The coolant reservoir (pictured in 2nd picture above) are prone to cracking and leaking in 996/997's. Have a good look at that.

I will cheers. Spoke to my mechanic and he reckons it’s the water pump. Going to tow to him tomorrow.

POST 7Original post

Coolent hose and pump look to be the main offenders,  But as @sjm says good time to check your tank as well.

Tank is not an inexpensive replacement, and very fiddly.  I had one "in stock" that I hadn't got around to installing in my original 996.2, and ended up putting it in my GT3 when we had the engine out.  My mechanic noted it would have been a bitch to do with the engine in... Having just replaced the water pump and thermostat in my 996.1 during a recent mini refurb, my mechanic noted that the water pump he removed had a slightly damaged mating face on the block where a previous replacement hadn't been done correctly.   I recall seeing in an FCP Euro DIY video that you need to loosen off the engine mounts and slightly jack up the engine to get the pump on and off properly.  I also replaced the water hoses as preventative maintenance, and some of these had to come from Germany. So @Rerve , depending on what is required, your's might be a bit longer job than you thought, depending on what parts you end up needing??  I got my waterpump from Masterparts / Autohaus Hamilton as it was substantially cheaper than Porsche.

POST 9 / ORIGINAL POSTEROriginal post

Thanks for all the info folks. She's on the way to the mechanic now. Will report back the result.

POST 10Original post

What did the Spanner man have to say ? How was the guess work ?

POST 11Original post

From a car that vintage plastics like expansion tanks can become brittle , well if that’s the issue? 🤷‍♂️ but no, not cheap for plastic.

POST 12Original post

In my 996.2 had the same leak but minor for few months.  One day I start the engine and the water pump started making rattle noise. I chose to drop the engine to change the pump and refurbish all that needs refurbishing. The pump was original and lasted 20 years. Not too shabby.
