C6 cooling system help
06 service manual isn’t out here, so, I am hoping someone that has the 05 service manual could help me out….how does the c6 coolant system work? There is no radiator cap on the radiator? It looks like the cap is actually on the reserve tank. If that is the case, does that mean the reservoir is also pressurized? And if it is when the car heats up and coolant overflow where does it go from the reservoir / radiator…..on the ground? I am use to radiator cap on the radiator and when it heats up, overflow just flows over to the reservoir and when it cools down coolant flows back to the radiator….i just not understand how the c6 coolant work….is this reverse flow system too? Which hose is the return hose from the engine block? What is the torque spec for the thermostat housing bolts? Thank you.

This is more owner's manual than shop manual stuff.
Yes, the reserve is pressurized - remove that cap with caution.
The reserve contains air space for expansion.
Some mid-engine cars have used a similar setup with a pressurized reserve tank. It may be used here due to the radiator being lower than the highest water level in the engine (which is part of the reason for using it on mid-engined cars).
No, it's not a reverse-flow. GM gave that up with the LS1.
There is a TSB about the low coolant level system not being real good at detecting low coolant levels; occasional visual checks are recommended. The reserve tank is translucent, you can see the coolant level by looking if there's enough light on the other side of it.

And, normally the thermostat is in the "discharge" side on an engine. Water flows from the engine, through the thermostat, to the radiator. The supply side would be lower on the engine and radiator.
