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 everything is dry in there too. With further inspection under the car it seems like it’s coming from top of the engine and way back away from water pump. I went on top the engine and saw a little puddle of coolant (pink) sitting on top of the engine (car was running at running temp) vacuumed it to see any new leaks and couldn’t see anything leaking anymore. My question is are there any hoses or anymore coolant system parts under the throttle body that I should be aware of? That was May 12, I’ve been keeping an eye under the car, and coolant level and can’t see anything leaking under the car anymore. I’m assuming the small leak on top the engine gets burnt off and doesn’t make it down. Car is running perfectly, not overheating or flashing temp light. I’m very skilled and comfortable working in the car but since I’m new to it I would like to know what I’m getting into.
Sorry for the long post
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?
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
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. It looks like it would remove straight down if the mount wasn't in the way, and maybe it could be removed and replaced from the top side, but that's very tight with pulleys. There must be a way to get this part out without removing the engine? This is not a commonly replaced part- the parts guy at the dealer said he has only sold one of these in several years, and I see no mention of replacing it in the 5000 page factory workshop manual or anywhere on the internet. Does anyone have experience with replacing this part with the engine in the car? I would appreciate any insight, and would even pay for a solution. I would like to get the car back on the road. Summer is very short here in Minnesota.
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
