Even Though the Manual says to remove the ´drain bolt´ on the water pump, to drain the coolant, DO NOT DO THIS! Loosen the Hose Clamp on the ´front´ of the pump and pull the hose off! WHY? The Gasket for the front of the pump going INSIDE 3 of the bolts, but OUTSIDE the other. Coolant/water gets on the threads of this bolt, corrodes it in place, and you may BREAK IT OFF! A REAL %!¤ IF YOUR ON THE ROAD!
