[Water Warrior 2]

There is a drain tube from the air box leading down to the bottom of the frame. It should have a plug in the end. Remove the plug and drain any fluids out. Replace the plug(this is a must do). The air box does get contaminants from blow-by and just general operating conditions. If the air filter is contaminated you best get a new one. Also keep in mind the air filter must be removed for inspection. The air fliter has a reverse flow and gets dirty from the inside to the outside.
