NOTICE
Improper or incomplete rinsing of the cooling system
can result in damage to copper and other metal
components.
To avoid damage to the cooling system, make sure to
completely flush the cooling system with clear water.
Continue to flush the system until all signs of the
cleaning agent are gone.
5. Stop the engine and allow the engine to cool.
Loosen the cooling system filler cap slowly to
relieve any pressure. Remove the cooling system
filler cap. Remove the connection hose or remove
the cooling system drain plugs. Allow the water to
drain. Flush the cooling system with clean water.
Install the connection hose. Install all drain plugs
and tighten securely.

NOTICE
Do not fill the cooling system faster than 5 L
(1.3 US gal) per minute to avoid air locks.
Cooling system air locks may result in engine
damage.
1. Fill the cooling system with the coolant/antifreeze.
Refer to this Operation and Maintenance Manual,
“Refill Capacities and Recommendations” topic
(Maintenance Section) for more information on
cooling system specifications. Do not install the
cooling system filler cap.
2. Start and run the engine at low idle. Increase the
engine rpm to high idle. Operate the engine to
open the engine thermostat. This operation will
allow any air in the system to be purged. Decrease
the engine speed to low idle. Stop the engine.
3. Maintain the coolant level at the maximum mark
that is correct for your application. Refer to this
Operation and Maintenance Manual, “Coolant
Level - Check” for more information.

4. Clean the cooling system filler cap and check the
condition of the filler cap gasket (2). Replace the
cooling system filler cap if the filler cap gasket (2)
and sealing surface (1) are damaged. If the
cooling system filler cap is not damaged, perform
a pressure test on the filler cap.
• Radiator cap pressure for three cylinder engine
95 kPa (13.7 psi)
• Radiator cap pressure for four cylinder engine
110 kPa (15.9 psi)
If the cooling system filler cap passes the pressure
test check, install the filler cap. If required install
new cooling system filler cap.
5. Start the engine. Inspect the cooling system for
leaks and for the correct operating temperature.
