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.
2. Fill the cooling system with Perkins (ELC). Refer to
the Operation and Maintenance Manual, "Fluid
Recommendations" topic (Maintenance Section)
for more information on cooling system
specifications.
Note: Ensure that the filler cap is installed before
operating the engine.
3. Install power to the engine. Start the engine.
Operate the engine to purge the air from the
cavities of the engine block. Use the normal
shutdown procedure to stop the engine.
4. Isolate the electrical supply to the engine. Remove
the filler cap. Check that the coolant level is within
25 mm (1.0 inch) of the bottom of the filler pipe.
5. Install the cooling system filler cap.
6. Install power to the engine. Start the engine and
operate the engine. Inspect the cooling system for
leaks. Ensure that the cooling system operates at

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 contain-
ers before opening any compartment or disassem-
bling any component containing fluids.
Dispose of all fluids according to Local regulations
and mandates.
NOTICE
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 of the coolant 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: Refer to Perkins Diesel Engines Fluids
Recommendations, Coolant Recommendations
(General Maintenance) for more information on the
service life of the recommended coolants.
Note: When the cooling system is cleaned, only
clean water is needed when the coolant is drained
and replaced.
Note: Inspect the water pumps and the water
temperature regulators after the cooling system has
been drained. This is a good opportunity to replace
the water pumps, the water temperature regulators
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
i08381139
pressure.
