Cooling System-Draining

CAUTION: Avoid being scalded when radiator cap is removed. First turn cap slightly to the radiator stop. This lets steam safely out the vent. Never open radiator cap when engine is hot. Allow system to cool before draining radiator.

Every two years or 1500 hours, drain cooling system by opening drain on bottom side of radiator (A) and drain above engine crankshaft (B).
