I got an 2001 996tt 29k miles on it, and I'm getting a nice candy coating on the drivers side of my motor. Pulled the alternator, y pipe boost hoses etc. and can see its getting on top of the motor and running down the side.
It's not enough to leave a puddle on the ground nor is it enough to notice any kind of drop in the coolant reservoir. I noticed it this spring and tried using a bore scope to peak around on top of the motor to find a wet hose or the classic fitting releasing but unfortunately it's tight up there and hard to trace what I'm looking at or where the hoses, fittings are to have start points.
It seems pretty minimal but it's annoying.
I checked the reservoir tank, don't think it's there but not 100%, I have the old tank.
Checked around the water pump, all good there.
As well as I pressure tested it several times and didnt lose any pressure even after letting it sit for hours. Warm and cold.
So if anybody has a diagram of the coolant hose placement or any suggestions let me know.
As the time has passed from spring(when I first noticed it) till now it hasn't changed, no worse no better. Still minimal , just looks bad when you stick your head under the car on the drivers side.

 

or here:

it will have the info which may help you locate your cooling system routing... and many other useful details....

 

A few things up top that can leak, including a handful of the aluminum tube fittings that like to pop out as well as the oil cooler orings.

The link that was provided there for the manual will have some stuff, but I can also email some of the PET diagrams of necessary, although they are not always the best for proper representation of the parts as they sit on the car/engine.

 

Thanks rich, I have looked at the manual, almost too much info there it's hard to locate exactly what I need in terms of the hose routing etc. but appreciate the help.
Rennfab, I will pm you my email if you have something outside of the manual or know exactly where to look in it.
It seemed like its coming from the back of the motor, and running down the center seam on the block, pooling up in the dips and crevasses and finding its way over the edge but only on the drivers side.
Does anybody have any motor out pics that you could post so I can see what is all back there.
Funny if this was any other car I'd have this fixed in two seconds, wouldn't it be nice if Porsche built a removable panel inside the car to access the rear top of the motor.

 

Emailing you some diagrams in the vicinity you requested now

 

Thanks Adam got it. Super helpful.

 

Looking at the rear of the car there is a large coolant hose on the right that comes out of the engine block (like 2 inches thick) can someone help with parts diagrams that I need to replace that hose that exploded and cant find the part number please. 996TT

 

All the coolant hoses part#: But I think you are talking about 996-106-501-74...
