Coolant: Procedures

COOLING SYSTEM FLUSHING - 2.5L

1. To remove rust, sludge and other foreign material from the cooling system, use cooling system flush that is safe for use with aluminum radiators.

For additional information, see  See: Engine, Cooling and Exhaust/Engine/Specifications. 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.

2. Remove the radiator. See - See: Engine, Cooling and Exhaust/Cooling System/Radiator/Service and Repair.

3. Backflush the radiator with the radiator in an upside-down position with a high-pressure hose in the lower hose location and backflush.

CAUTION:Radiator internal pressure must not exceed 138 kPa (20 psi). Damage to the radiator can result. 

4. Remove the thermostat. See - See: Engine, Cooling and Exhaust/Cooling System/Radiator/Service and Repair.

NOTE:The thermostat and housing are serviced as an assembly. 

5. Backflush the engine. Position the high-pressure water hose into the engine through the engine return and backflush the engine.
