2006 cobalt ss 2.0 supercharger coolant
 

2006 ss cobalt 2.0 supercharged:
what type of fluid is used in the supercharger system?
should the fluid level be visible below cap, in fill neck?

The water to air cooling system uses 50/50 dexcool.

The supercharger itself has its own lubrication
It holds 3-4oz drain and fill. somewhere around 5-6oz from completely dry.
The oil part number is 12345982. Comes in either 8oz(old) or 4oz(new) bottle depending on if you get one of the old bottles or new bottles. Currently here at work we only have the newer 4oz so that's probably what you'll find at other dealers.

if it holds 3 to 4oz then that's it there is no dry fill capacity if you do not know the correct information then don't post your best guess
