Just wondering best way to go about doing a coolant flush, i get the jist of it, but nothing in detail about the 2007 vectra is it as simple as it seems? drain radiator at bottom when emptied, re-tighten the valve/seal then fill up from expansion tank (leaving the cap off?), then run the engine with heater on and fill up tank when needed til it doesn't lower anymore? what am i missing (if anything) Thanks ahead of time!
