I refresh my BMW's cooling system and it tries to kill me! Project E34 Part 5

In this episode I fix the broken heater (secondary water pump), refresh the entire cooling system/belts/pulleys, and avoid death by electrocution! I also get the engine running again, but not without some last minute hiccups.
