SC Heat Exchanger Leak?
Gents, need some help/input on a potential issue with my Z06 SC heat exchanger. I'm new to superchargers so this may be a stupid question.
I noticed my SC coolant reservoir was only about half full and when opening the fill port at the top of the engine it was bone dry. Not good... Figured I simply had a lot of air in the system and all I needed to do was refill with coolant and bleed the system of air. Well, I started slowly refilling the system from the top port with coolant. Everything was going well but it was taking a lot. I added about 6 cups and then noticed coolant leaking under the car. I can't see exactly where it's coming from but it's definitely centerline and in front of the radiator...the SC heat exchanger I'm guessing.
My question: Does there happen to be some type of overflow or something in that area that would allow fluid to leak out? My guess is no since this is a closed system but I gotta ask before I assume the heat exchanger itself is leaking. Are there any connections in that area that would leak as well?

The most likely places for leaks are the Heat Exchanger (HX) located in front of the AC Condenser, the hoses that connect the HX to the SC manifold, the pump and the reservoir along with the pump and the reservoir. The HX is more likely since debris coming through the grill can punch holes in it.
I doubt there is a leak in the SC bricks since there is a high potential for the engine to hydrolock if a leak occurs in the bricks.
