I'm going to be installing an upgraded SC heat exchanger in the next couple of weeks. While I'm going that I figured I'd flush the system. I know it's as simple as removing a hose to drain things, but I also read that there is a lower point or better place to do it to get the maximum amount of fluid out of the block. I've read conflicting things on this: some say there is a valve other say you need to disconnect a hose from the oil cooler...?

Anyone know the best/proper spot to use for maximum drainage? This is for a 2013 if that matters.

Cheers!
