3. Fill the cooling system with Commercial Heavy-
Duty Coolant. Add Supplemental Coolant Additive
to the coolant. For the correct amount, refer to the
Operation and Maintenance Manual, "Fluid
Recommendations" topic (Maintenance Section)
for more information on cooling system
specifications. Do not install the cooling system
filler cap.
4. Start and run the engine at low idle. Increase the
engine rpm to high idle. Run the engine at high
idle for one minute to purge the air from the
cavities of the engine block. Stop the engine.
5. Check the coolant level. Maintain the coolant level
within 13 mm (0.5 inch) below the bottom of the
pipe for filling. Maintain the coolant level in the
expansion bottle (if equipped) at the correct level.
6. Clean the cooling system filler cap. Inspect the
gasket that is on the cooling system filler cap. If
the gasket that is on the cooling system filler cap is
damaged, discard the old cooling system filler cap
and install a new cooling system filler cap. If the
gasket that is on the cooling system filler cap is not
damaged, use a suitable pressurizing pump to
pressure test the cooling system filler cap. The
correct pressure for the cooling system filler cap is
stamped on the face of the cooling system filler
cap. If the cooling system filler cap does not retain
the correct pressure, install a new cooling system
filler cap.
7. Start the engine. Inspect the cooling system for
leaks and for correct operating temperature.

Care must be taken to ensure that fluids are con-
tained during performance of inspection, mainte-
nance, testing, adjusting and repair of the product.
Be prepared to collect the fluid with suitable contain-
ers before opening any compartment or disassem-
bling any component containing fluids.
Dispose of all fluids according to Local regulations
and mandates.
Keep all parts clean from contaminants.
Contaminants may cause rapid wear and shortened
component life.

NOTICE
NOTICE
Clean the cooling system and flush the cooling
system before the recommended maintenance
interval if the following conditions exist:
• The engine overheats frequently.
• Foaming is observed.
• The oil has entered the cooling system and the
coolant is contaminated.
• The fuel has entered the cooling system and the
coolant is contaminated.
Note: When the cooling system is cleaned, only
clean water is needed when the ELC is drained and
replaced.
Note: Inspect the water pump and the water
temperature regulator after the cooling system has
been drained. During this maintenance procedure,
consider replacing the water pump, the water
temperature regulator, and the hoses, if necessary.
Drain
Pressurized System: Hot coolant can cause seri-
ous burns. To open the cooling system filler cap,
stop the engine and wait until the cooling system
components are cool. Loosen the cooling system
pressure cap slowly in order to relieve the
pressure.
1. 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.
