  1. Greetings - I have traced a coolant leak to the rear of the alternator - wondering if anyone else has seen this and whether its repairable or I just have to commit to replacing it (once I can find a replacement - they seem to be rather hard to find at the moment).... Cheers.
  2. My 2004 Carrera coupe has developed a leak. It started after I flushed my cooling system. Rather sure it is around the AOS/associated lines. I've read various opinions about the difficulty of removing the AOS. But what I am interested in doing is just replacing those lines. Any experience or opinions on doing this? Specifically, is it even possible? Especially if this can be done without removing the intake manifold? Also I am only finding the upper oil separator coolant hose. What about the second one?
  3. Hi there, new to the forum and new to Boxster 986 (2months). I recently discovered that my Boxster is leaking coolant, it all started when I parked it for like 5 hours in a slanted spot with the weight going towards the driver side, came back to go back home and noticed a big mark of coolant under the car. Once I got home I checked the water pump and thermostat area and that’s all dry and no bad signs on the pump at all (there were changed by previews owner about 3 years ago) also not a bad reservoir tank, it’s all dry under the carpet and removed the lid to see the release valve and ever
  4. At first I thought the water pump was leaking, but with careful examination, discovered the plastic "Water Guide Housing" (P/N 987-106-508-04) used to route coolant from the front of the engine to the front radiators, sprung a rather large leak at the mold seam on the bottom of the part near where it makes a 90 degree bend and joins the "Henn" fitting on the large rubber hose. I removed the 9 screws attaching the housing to the engine, and have a new replacement part, but can't figure out how to get it out, because it snakes around the front engine mount, which looks very difficult to remove.
  5. I am looking for some help with regards to a coolant leak. I got a red blinking temperature gauge warning. The 996 overheated. The coolant leak is on the top of the engine near where the transmission and the block bolt together. The leak appears to dominate towards the passenger side of the 996. When I start the 996, coolant streams out from the area as I mentioned. Reference graphic for a better picture. Has anyone experienced this same leak or is familiar with what would cause this leak? Durametric does not give any faults or warnings. Any Ideas? Thanks, Ken
  6. While changing my oil yesterday, I noticed what looks likes coolant "weeping" (no drip yet) from this engine block plate located on the passenger side toward the front of the car. I have not yet noticed any loss in my coolant tank level. However, I'm thinking it is only a matter of time. So, if I am correct, this part is referenced in the parts catalogue as simply a "lid" but there is a gasket here which I should replace with the Porsche part number 996-101-336-50, and I will need to flush/replace the entire coolant system in the process. My coolant had been replaced by a previous owner with
  7. I have a 2003 996 Carrera cab. When I got to work this morning I noticed coolant flowing from rear of engine compartment. The temp gauge never peaked, and none of the idiot lights came on. Any ideas on what this problem is would be greatly appreciated. Thank you in advance
  8. My 955 turbo has consumed nearly 10L of coolant in the past 40 days. No apparent exterior leak (haven't opened up engine covers yet). White smoke exhaust upon cool-cold start up, tubes are done. Cooling system seems pressurized when I open reservoir cap. Apart from head gasket potential are there any other possibilities? Through intake somehow? Through turbos? Doesn't overheat. Help please
  9. I am trying to locate a coolant leak on my '99 996. It is leaking pretty significantly near the rear of the engine (by the timing chain cover, closest to the rear seats), somewhere up here: I have ruled out the expansion tank; I disconnected a few pipes and was able to run my hand all along the back of it and it came back bone dry. Meanwhile I can see rivulets of coolant running down the rear of the engine. I put the car up on jackstands, but visibility up there is extremely limited. I unfortunately do not have access to a lift. I was wondering if there was any way to diagnose/resolve the
  10. I know this is a topic often reviewed here on the forum but I was looking for a little more help prior to just letting my local mechanic ream me for a few thousand dollars. Use the forum often, rarely (if ever) post, but have been far more active on equivalent sites for cars I've owned in past (Audi/BMW/etc)... Have an 04 Cay S, 87k miles, owner for past 16 months, probably drive 1200-1500mi/month. About 2 months ago, in traffic temp gauge went above 220 - i know it is very common for it to fluctuate in that 180-220 range but this was first ever time it went beyond. Was home about 1 mile lat
  11. Need help here. My 2000 996 coupe RWD, 6MT has a weird coolant drip issue that seems to heal itself. Last week after taking the car out for a brief run, I noticed a coolant drip hitting the dirver side exhaust tip. Knowing that this is the prime indicator of a coolant tank issue, I took the car over to my techs. The car cooled down, and showed NO signs of a leak anywhere? After a visual and finally a pressure test of the system, we came to the conclusion that the cap was the problem ( old cap ending in 00 ). We got a new cap the following day, topped off the tank, re checked and went on
  12. Boxster-mates, I need your insights here. On the drive back this evening - 111F in Phoenix - the AC cooling was low. I also felt a bit of squeal coming from the behind the dashboard when the compressor was running - a mechanical-ish squeal. The engine temperature was near high 190s. After I parked the car, noticed the green coolant spots - not many or large - two or so (I've attached some photos). Some history on the replacements so far, 1) 7/2009 - AC compressor was replaced 2) 7/2011 - Cracked coolant reservoir was replaced. I don't see any coolant under the tank (as in attached
  13. Alright, 2 weeks ago I bought an '03 996 Cabriolet from a physician friend of mine... After driving it for two weeks I noticed a large puddle of coolant on the garage floor. The coolant leak was coming from the back drivers side of the engine (pics to follow) After researching this topic thoroughly over the weekend I am confident that I can execute his repair myself... But first, let me stress to everyone that I AM NOT A MECHANIC, nor have I ever attempted any "mechanics" except for oil & filter changes. There are some really great write-ups that gave me the confidence and know-how t
