After getting splashed in the face with coolant the other night, I realized that I had never seen any good tips on draining the block other than where the bolt is and what tools to use.
1. Follow the DIY:

2. The bolt is very short, so just loosen it and get out from under the car.
3. Back up topside, reach your left arm down and around the turbo and start feeling the block for the drain bolt.
4. Remove and let drain into a catch pan. Remove hoses per DIY to get full flow.
5. Replace in reverse. snug the bolt up from the topside, then get under the car and tighten per FSM.
