Where is Coolant drain 1986 Honda VT1100C?

The bolt to drain the coolant is on the water pump. The water pump is on the left side of the bike, just in front of the oil filter. Just remove the 10mm bolt CLOSEST TO THE OIL FILTER. You'll want to remove the radiator cap prior to doing this so the coolant drains freely. NOTE: Make sure the coolant is cold so you don't get scalded.
