After the coolant has drained completely, flush the system
with clear water and making certain to capture the drained
liquid in a container.
Correctly reattach the lower radiator hose. 1.
Mix new coolant using equal parts of clean tap water 2.
and new antifreeze.
Pour the new coolant into the radiator opening until the 3.
radiator fins are covered with coolant. Do not add the
new coolant at a rate faster than 5 l/min (1.3 gpm) to
reduce the risk of air pockets in the cooling system.
Install the radiator cap. 4.
Check the coolant level once again after half an hour 5.
of operation.
Changing the coolant
NOTICE
Replace the coolant after two years of use.
The coolant must consist of equal parts of water and
antifreeze. This mix guarantees an optimal ratio of
cooling performance and corrosion protection.
Do not exceed a refill rate of 5 l/min (1.3 gpm) to re-
duce the potential for air entrapment during filling.
Use the capacity guide on page 163. Fill until the
coolant is below the neck of the radiator cap spout.
Replace the cap and run the engine briefly.
Stop the engine and check the level. Add coolant if
the level has dropped.
Stop the loader on a horizontal surface and set the park- 1.
ing brake.
Lower the loader lift arms and attachment to the ground 2.
or the work surface..
Stop the engine. 3.
Refer to 4. Section 10.6, page 163 for the volume of cool-
ant and select a drain container of sufficient capacity
to avoid spillage.
Remove the radiator cap. 5.
Remove the lower radiator hose (remove the hose clamp 6.
and remove the hose).
