What's missing!?
 

So I got home this morning. And my car was overheating, absolutely no coolant in the reservoir. I started looking and noticed there is a spot for a hose to be attached but I have no idea where it goes. Can anyone help me identify what's supposed to be here?http://forums.pelicanparts.com/uploa...1456575722.jpg

Is that that bottom forward part of the coolant reservoir? Nope.. That can't be it.

What model car?
And what's with the brass plumbing fitting?

looks like the hose blew off. gotta be in there somewhere.

Do you have anymore pictures? Mabe from the top view of the motor, and one from the bottom, skid plate off, so we can get a better view?

That brass fitting looks like a head steam kit?

You're missing a hose. that's the one that goes parallel with the radiator.

Look how all of your hoses are wet, water/antifreeze droplets everywhere. That looks like your plastic coolant reservoir hose to the radiator was eaten by the cookie monster.

Download the 944 PET/Parts catalog from porsche and that will give you a great schematic of your coolant lines, and the part # needed to buy a new hose.
