ENGINE COOLING SYSTEM (CONT’D)
Removing And Replacing Coolant
Open the rear door and remove the rear grill.
Figure 190
Remove the coolant fill cap (Item 1) [Figure 190].
Connect a hose to the engine block drain valve (Item 3)
[Figure 190]. Open the drain valve and drain the coolant
into a container.
After all the coolant is removed, close the drain valve and
remove the hose. Recycle or dispose of coolant in an
environmentally safe manner.
Mix new coolant in a separate container. (See Capacities
on Page 172.)
NOTE: The loader is factory filled with propylene
glycol coolant (purple colour). DO NOT mix
propylene glycol with ethylene glycol.
Add premixed coolant, 47% water and 53% propylene
glycol to the recovery tank. (See Checking Level on Page
132.)
The correct mixture of coolant to provide a -37°C (-34°F)
freeze protection is 5 L propylene glycol mixed with 4,4 L
of water OR 1 U.S. gal propylene glycol mixed with 3.5 qt
of water.
Fill the tank until it is at the lower marker on the tank.
Use a refractometer to check the condition of propylene
glycol in your cooling system and replace the coolant fill
cap.
NOTE: When installing the coolant fill cap, the cap
must be tightened until it clicks.
Run the engine until it is at operating temperature. Stop
the engine. Check the coolant level when cool. Add
coolant as needed.
Install the rear grill and close the rear door.
Checking Level
Open the rear door and raise the rear grill.
Check coolant level using the level markers (Item 2)
[Figure 190] on the tank. Coolant must be at the bottom
marker when the engine is cold; top marker when hot.
Close the rear door before operating the loader.
AVOID ENGINE DAMAGE
Always use the correct ratio of water to antifreeze.
Too much antifreeze reduces cooling system
efficiency and may cause serious premature engine
damage.
Too little antifreeze reduces the additives which
protect the internal engine components; reduces the
boiling point and freeze protection of the system.
Always add a premixed solution. Adding full strength
concentrated coolant can cause serious premature
engine damage.

NOTE: All access covers (Item 1) [Figure 191] (both
sides) must be in place to ensure correct air
flow through the oil cooler which will ensure
cooling for engine and hydraulic system.
