Cooling System Coolant (ELC) - Change<br />
Clean the cooling system <strong>and</strong> flush the cooling<br />
system before the recommended maintenance<br />
interval if the following conditions exist:<br />
• The engine overheats frequently.<br />
• Foaming is observed.<br />
• The oil has entered the cooling system <strong>and</strong> the<br />
coolant is contaminated.<br />
• The fuel has entered the cooling system <strong>and</strong> the<br />
coolant is contaminated.<br />
Note: When the cooling system is cleaned, only<br />
clean water is needed when the ELC is drained <strong>and</strong><br />
replaced.<br />
Note: Inspect the water pump <strong>and</strong> the water<br />
temperature regulator after the cooling system has<br />
been drained. This is a good opportunity to replace<br />
the water pump, the water temperature regulator <strong>and</strong><br />
the hoses, if necessary.<br />
Drain<br />
Pressurized System: Hot coolant can cause serious<br />
burns. To open the cooling system filler cap,<br />
stop the engine <strong>and</strong> wait until the cooling system<br />
components are cool. Loosen the cooling system<br />
pressure cap slowly in order to relieve the pressure.<br />
1. Stop the engine <strong>and</strong> allow the engine to cool.<br />
Loosen the cooling system filler cap slowly in<br />
order to relieve any pressure. Remove the cooling<br />
system filler cap.<br />

2. Open the drain cock or remove the drain plug (1)<br />
on the engine. Open the drain cock or remove the<br />
drain plug on the radiator.<br />
Allow the coolant to drain.<br />
NOTICE<br />
Dispose of used engine coolant or recycle. Various<br />
methods have been proposed to reclaim used coolant<br />
for reuse in engine cooling systems. The full distillation<br />
procedure is the only method acceptable by <strong>Perkins</strong> to<br />
reclaim the coolant.<br />
For information regarding the disposal <strong>and</strong> the<br />
recycling of used coolant, consult your <strong>Perkins</strong> dealer<br />
or your <strong>Perkins</strong> distributor.<br />
Flush<br />
1. Flush the cooling system with clean water in order<br />
to remove any debris.<br />
2. Close the drain cock or install the drain plug in the<br />
engine. Close the drain cock or install the drain<br />
plug on the radiator.<br />
NOTICE<br />
Do not fill the cooling system faster than 5 L<br />
(1.3 US gal) per minute to avoid air locks.<br />
Cooling system air locks may result in engine damage.<br />
3. Fill the cooling system with clean water. Install the<br />
cooling system filler cap.
