Default 944 Coolant Leak near Radiator, need help

My 944 developed a leak yesterday. I had been driving it all summer with no issues. I got back from the store yesterday, parked in the garage, and went inside. I came back out later to find coolant all over the floor of my garage.

Today I did some looking into where it was coming from and filled up the coolant tank with water and ran the engine for a few minutes looking for leaks. Nothing was leaking. As soon as I stopped the engine, though, the leak started.

It is coming through one of the small holes in the piece just below the radiator on the passenger side of the car (as shown in the picture).




I'm not sure where to go from here. Is that part of the radiator, or is it separate? Is it possible to remove that to get at the whatever is above the metal piece? Any thoughts of where the leak may be originating from?

Thank you for the help.

Don't drive it until it's repaired.

That is the chassis radiator support and it has three holes across the bottom. it is not a removable part.

Any leak from either hose, the radiator, including the drain plug, vent and temperature switch, will show up there.

Buy or rent a pressure tester and pressurize the system. The leak will make itself very clear that way. This kind seals well in the 944:

i like the stant model as it comes with the cap adapter, metal and made in 'merica

The one I linked has a unique bladder arrangement that works on just about any car --but you can't go wrong with Stant stuff either. The one that doesn't work well (at least on the 951) is the knock-off sold by Harbor Freight -- the cap adapter just doesn't seal right.
