Flushing Cooling System

WARNING: To avoid being scalded, never change the coolant when the engine is hot.
Wrap a thick cloth around cap and carefully remove the cap. First, turn the cap a quarter of a turn to release built-up pressure. Then turn the cap all the way.
Be careful not to allow coolant to contact drive belts.
