Turns out it doesn't have
a radiator drain plug.
Not exact matches
After removing the blue
drain plug (my car only had one, apparently some cars have two) on the bottom of the
radiator and another
drain plug on the side of the engine under the exhaust manifold, my expansion tank still has a bunch of coolant left in it.
Yet to
drain the coolant usually the procedure is to use the
drain plug at the
radiator.
A similar method is to get length of hose, like
radiator / heater hose that will slip snugly over the head of the
drain plug (assuming it's an outie, not an innie).
