Yeah on this bit: I've seen the difference looking at a 12's engine bay in person before. They actually have what looks like a real pressure cap on the overflow bottle, and... something else where our pressure cap is. I think.
I wonder if our 09 system can be updated just by replacing the rad cap and the overflow bottle with the newer bits?
