Flushing
WARNING:
Always allow the engine to cool before opening the cooling
system. Do not unscrew the coolant pressure relief cap when the engine
is operating or the cooling system is hot. The cooling system is under
pressure; steam and hot liquid can come out forcefully when the cap is
loosened slightly. Failure to follow these instructions may result in
serious personal injury.
NOTE:
To remove rust, sludge and other foreign material from the
cooling system, use cooling system flush that is safe for use with
aluminum radiators. This cleaning restores cooling system efficiency and
helps prevent overheating. A pulsating or reversed direction of
flushing water will loosen sediment more quickly than a steady flow in
the normal coolant flow direction. In severe cases where cleaning
solvents will not clean the cooling system efficiently, it will be
necessary to use the pressure flushing method using cooling system
flusher. Dispose of old coolant and flushing water contaminated with
antifreeze and cleaning chemicals in accordance with local, state or
federal laws.
