NOTICE
Care must be taken to ensure that fluids are contained
during performance of inspection, maintenance, test-
ing, adjusting and repair of the product. Be prepared to
collect the fluid with suitable containers before open-
ing any compartment or disassembling any compo-
nent 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 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 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 pres-
sure.
1. Stop the engine and allow the engine to cool.

2. Open the drain cock or remove the drain plug (1)
on the engine. Open the drain cock or remove the
drain plug on the radiator.
Allow the coolant to drain.
Dispose of used engine coolant or recycle. Various
methods have been proposed to reclaim used coolant
for reuse in engine cooling systems. The full distillation
procedure is the only method acceptable by Perkins to
reclaim the coolant.
For information regarding the disposal and the
recycling of used coolant, consult your Perkins dealer
or your Perkins distributor.
Flush
1. Flush the cooling system with clean water in order
to remove any debris.
2. Close the drain cock or install the drain plug in the
engine. Close the drain cock or install the drain
plug on the radiator.
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.
3. Fill the cooling system with clean water. Install the
cooling system filler cap.
4. Start and run the engine at low idle until the
temperature reaches 49 to 66 °C (120 to 150 °F).
