2. 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.
3. Start and run the engine at low idle. Increase the
engine rpm to high idle. Run the engine at high idle
for 1 minute in order to purge the air from the
cavities of the engine block. Stop the engine.
4. 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.
5. 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 in
order 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.
6. Start the engine. Inspect the cooling system for
leaks and for correct operating temperature.

NOTICE
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 containers
before opening any compartment or disassembling
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.
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. This inspection is a good opportunity to
replace 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
i05907641
pressure.
1. Stop the engine and allow the engine to cool.
Loosen the cooling system filler cap slowly in order
to relieve any pressure. Remove the cooling
system filler cap.
