Radiator cap?
Does the C5 have a radiator cap under the shroud or is the only place to put in water... the reservoir? I want to put some "water wetter" directly into the radiator.

...as soon as your start the car and the thermostat opens, the water pump will circulate the WATER WETTER through the entire system. Doing it your way might introduce air into the system resulting in fluctuating coolant temperatures and other issues to the oem coolant.
