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

Dripping coolant but all I can see is it's dripping off the header. Cant really see anything specific it's dripping from. Very small drip. Any thoughts on a common issue here?

POST 2Original post

Is it dripping just in front of the left rear tire? If so, that is either the coolant cap or the coolant tank. Newest cap part number ends in 04 or 05. Tank replacement is potentially a DIY, but it is a tight fit. If you DIY it, by the time you are finished you will learn a bunch of new ways to string cuss words together!

POST 3Original post

right side Tim... though it could be moving over there I suspect the coolant hose/connection... pull out the air filter box and you can see WAY more areas that might help find the problem (its a 5 minute operation)

POST 4 / ORIGINAL POSTEROriginal post

Pulled out the air cleaner and didn't find anything obvious. Crawled under the rear of the car and did see coolant around the header and misc shields and covers. It looks like it's coming from somewhere behind the heat shield that covers the spark plugs. I'm gonna jack it up and pull it apart later to see if I can tell exactly where it's coming from. It's definatly not coming from the main coolant hose as it is all bone dry along with all the other hoses and parts I can see from the top of the engine.

OOPS! I missed the "passenger rear" in the title.

POST 6Original post

I'm interested to hear what you find. i find some dried coolant in that area at times but i can never track down the source.

POST 7Original post

Chances are that you or someone like you has pinched the coolant line that is just ahead of the jack point during a jacking exercise. I looked at mine the other day and saw that it was nicely kinked. Kinda like the oil lines on the old air cooled lines. It was very common to pinch these. Let us know if this is the case and if so what is involved ($) with fixing it. I don't like how mine is pinched.

POST 8Original post

air cleaner or entire air box? cant remember whats up there on Pass side... my guess is topside and its running down...can you get the car up in the air and roll under it?

POST 9Original post

oops - I missed the part about dripping from the header.

POST 10 / ORIGINAL POSTEROriginal post

I see the pipe that it's dripping down (see the attached picture). There are two hardline pipes. The one towards the rear is the one with all the fluid. It appears to be coming from the top of this pipe but I cant see in the engine enough to tell for sure thats where it's actually leaking from. Anyone know what these pipes are called and how hard it would be to replace/fix. I dont even see how I can get to the top of the pipe.

POST 11 / ORIGINAL POSTEROriginal post

Before I get any smart remarks...the picture of the engine is NOT my engine!

POST 12 / ORIGINAL POSTEROriginal post

OK...so with the help of the picture, I figured out that those things that I thought were some sort of hard line, are not lines at all, they are brackets. Soo...then I looked around the bracket and still didn't see anything. Started the car up and let the drip start happending again and I found it! It is definatly leaking from the main waterline, right where the rubber connects to the hard line. Looks like just a spring holds that thing on there. Is it as simple as pulling the spring off and then the hose? It's a wierd place for it to all of a sudden start leaking though.

POST 13Original post

The arrow is pointing to the muffler mount. Are you sure it's leaking from there, because that would be bad.... Rick 99 996C4 87 944S

POST 15Original post

OH DAYAM.... you need a new muffler bracket sorry, no motor like that to go look at .... someone will know what's there, most likely a hose

POST 16 / ORIGINAL POSTEROriginal post

Popped off the spring and the lower clamp. Got the lower part off but the upper is really stuck in there. Does just the rubber part come out of the inside of the hard line (with the clamp thingy on it) or do I need to also remove the hardline further back.

POST 17 / ORIGINAL POSTEROriginal post

OK...got the hose out...just had to pry and pull on it. I think I must use a porsche specific hose as it's pressurized and has an o-ring. Attached pic is how it failed. Crack in the aluminum backet. Thanks for the help & support

POST 18Original post

Another crack in the aluminum part! Good thing it's not a head.

POST 19 / ORIGINAL POSTEROriginal post

Well, I was on vacation for a week so couldn't update. Got back on Tuesday, got the parts for a 997, required me to change out to another spring type connector on the engine side, total parts cost was about $70. I pulled the serpantine belt (replaced with new), put on the new adapter, put on the new hose, serpantine belt. Within 20 minutes it was all done and back together. Started the car up, no leaks! Thanks for the help and advise!
