Cooling System
Daily Checks:
The loader is equipped with a liquid cooled diesel engine
that requires daily coolant level checks and radiator ser-
vice if necessary.
The cooling system should always be checked when the
engine is cool.
Park the loader on a level surface, lower the boom arms,
engage the parking brake and shut off the engine.
1 Access the engine compartment by opening the rear
door and lifting the engine compartment cover.
2 Visually inspect the radiator cooling fins for broken
or bent fins, dirt or debris build up that may be blocking
air flow through the radiator. Blow any dirt or debris out
with compressed air and / or water. Do not exceed 40 psi
(2.7 kg / cm
2
) Any bent cooling fins should be carefully
straightened to prevent core damage.
3 Remove the rad cap to check the coolant level.
Coolent level should be no more than 1/2 inch below the
seat for the rad cap.
Always use a 50/50 ethylene glycol/water mixture to
top up the cooling system.
4 If the coolant level constantly falls below the upper
part of the radiator tank, then either the radiator cap is
defective allowing coolant to escape under pressure, or
there is a coolant leak in the cooling system. Perform a
pressure test of the cooling system.
Testing the Cooling System:
1 Ensure the radiator is full of coolant.
2 Start the engine operate until warm, NOT HOT!
3 Shut off the engine and carefully remove the radiator
cap. Use extreme caution.
When pressure testing the cooling system, do not
exceed 12.8 psi.(0.9 kg/cm2)

WARNING
To prevent eye injury, wear safety goggles when
cleaning with compressed air
CAUTION
To prevent radiator fin damage, do not use air pres-
sure higher than 40 psi (2.7 kg / cm

)
WARNING
Do not remove the radiator cap when the engine is
hot.
WARNING
Always use a pre - mixed or diluted coolant to pre-
vent engine over heating, freezing and proper water
pump lubrication
