Cooling System Flushing
1. To remove rust, sludge and other foreign
material from the cooling system, use
Premium Cooling System Flush that is safe
for use with aluminum radiators, for additional information,
refer to Specifications in this section.
Remove the thermostat prior
to pressure flushing. 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 properly clean the cooling system for
efficient operation, 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.
2. Remove the radiator.
3.
CAUTION: Radiator internal pressure
must not exceed 138 kPa. Damage
may result.
Back flush the radiator with the radiator in
an upside down position with a high-
pressure water hose in the lower hose
location and back flush.
4. Remove thermostat.
Refer to Thermostat in this Section.
5. Back flush the engine. Position the high-
pressure water hose into the engine
through the engine return and back flush
the engine.
