After the coolant has drained completely, flush the system
with clear water and making certain to capture the drained
liquid in a container.
1. Correctly reattach the lower radiator hose.
2. Mix new coolant using equal parts of clean tap water
and new antifreeze.
3. Pour the new coolant into the radiator opening until the
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.
4. Install the radiator cap.
5. Check the coolant level once again after half an hour
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
reduce the potential for air entrapment during filling.
Use the capacity guide on page 155. 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.
1. Stop the loader on a horizontal surface and set the park-
ing brake.
2. Lower the loader lift arms and attachment to the ground
or the work surface..
3. Stop the engine.
4. Refer to Section 10.6, page 155 for the volume of cool-
ant and select a drain container of sufficient capacity
to avoid spillage.
5. Remove the radiator cap.
6. Remove the lower radiator hose (remove the hose clamp
and remove the hose).
