• The oil has entered the cooling system and the
coolant is contaminated.
• The fuel has entered the cooling system and the
coolant is contaminated.
REMARQUE
When any servicing or repair of the engine cooling
system is performed, the procedure must be perfor-
med with the engine on level ground. Level ground
will allow you to check accurately the coolant level.
This procedure will also help in avoiding the risk of in-
troducing an air lock into the coolant system.
Nota: 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
Circuit sous pression: Le liquide de refroidisse-
ment chaud peut provoquer de graves brûlures.
Avant de dévisser le bouchon de remplissage du
circuit de refroidissement, couper le moteur et at-
tendre que les pièces du circuit de refroidisse-
ment aient refroidi. Dévisser ensuite lentement le
bouchon de remplissage du circuit de refroidis-
sement pour détendre la pression.
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

Flush
Cleaning agents for an industrial cooling system must
not be used. These cleaning agents are very aggres-
sive and cause damage to the cooling system
components.
1. Flush the cooling system with clean water and a
2. Clean the drain plugs. Install the drain plugs.
Ne pas remplir le circuit de refroidissement à raison
de plus de 5 l (1,3 US gal) par minute pour éviter les
poches d'air.
La présence de poches d'air dans le circuit de refroi-
dissement risque d'endommager le moteur.
3. Fill the cooling system with clean water and install
drain cock or remove the drain plug on the
radiator.
Allow the coolant to drain into a suitable container.
