Oh man, that really stinks. If the heat exchanger is good, then I don't know what it could be other than a bad head or a cracked/porous block. Good luck. Let me know what you find out.
I just bought a 03 Boxster S with 60 K Miles and after driving it for just 500 Miles, it over heated and when I opened the trunk, the dreaded 'Mochachino' was oozing out of the radiator cap. The Heatexchanger was removed and turned out to be OK. The Cam shaft was replaced by the previous owner , as were the head Gaskets, 6 months ago.
Any idea where the problem might be?
I'm really bummed! I was in heaven for the few short days that I drove it
Thanks for this. I have a 2001 996 with 83K. No problems with the water pump yet, but had to replace the expansion tank at 70k. I assume you hear it when the pump starts to go?
My car just went onto a flatbed. I called my mechanic when it started making noise & asked if the pump would clatter if it was going bad (I was thinking the worst, engine wise that is) & he told me most definitely. He suggested I have it towed from my house rather than attempt driving as a safety precaution.
Thanks for the video as I now have some idea what he will have to go through!! - Cam
Very nice video! I have a 996 and I can see some coolant residue on the water. Should that be concern? There are no noises coming from the water pump. By the way what ratio of water to antifreeze did you put in there? Thanks!

I noticed "green" - old school coolant when the pump was removed. My understanding is the 'correct" coolant is factory Porsche coolant which is pink in color... Maybe the wrong coolant helped finish the old pump off....
@MetalTeamster Water pumps have sealed bearings. The coolant never comes in contact with anything but the spinning impeller. You could pump any kind of fluid with them, and it would have no affect on how long the bearings last. Personally, I think the generic "mixes with anything - works in all cooling systems" coolant is just as good as the more expensive Porsche coolant, but use what you feel comfortable with in your car.
Very god vid, my 996 has 78k, and it is making a strange noise at start up for 15-20sec , the check engine light goes on, then goes off about the time the noise goes away. No coolant leak so far. Was your 996 making that strange noise about the time the pump went out?

I had approximately 107,000 miles on the car when the original water pump went bad, but that's exceptionally long life. I'm hearing the norm is about 75k. I replaced mine with a rebuilt unit from NAPA, but unfortunately that unit only lasted 6 months. I replaced it again under warranty, but I suggest sourcing one from ebay seller deutschepartsusa with a metal impeller. I hear they're good quality and cheaper.
Perfect informations ... I leave in france,! I have a 996 carerra4S model 2004...
The pump broke yesterday , so i will disassembly without problem ... Many thanks for your precious video

@MetalTeamster It was making a strange noise. The siezed bearings in the pump made it sound like a loud diesel engine or something.

Just out of curiosity, how many miles did you have on your 996 prior to the pump needing replacement?
