Ok so I am currently flushing out my engine coolant. I went and bought some engine coolant flush from autozone, and put it in with new water, and according to the directions I need to let the car run for 4-6 hours, then drain it. My question is, can I just let the car idle for 4 hours in my drive way instead of drive it and that'll be good? I don't want to go out and drive the car for that loing of a period of time right now, but i do want to get this flush done today, b/c it will be way below 80 degrees here tommorow 
Working with water in a cold garage is a PITA when it's cold. Anyways, just want to make sure this is safe for my car. I would assume so, since it's easier on the engine than driving it for 4-6 hours I would think. Also, I know it will not overheat b/c my cooling system is all fully upgraded and it has alreay been idling for about 30 minutes and the needle hasn't budged. I figur I can just keep shecking on it like every 20 minutes or so inbetween my studying for my finals here. Also, it's only 80 here so it isn't too hott so it REALLY shouldn't overheat. Anyways, thanks for the help guys! Mike.
