ENGINE COOLING SYSTEM
Checking The Coolant Level
Check the cooling system every day to prevent
over–heating, loss of performance or engine damage.
Open the rear door. Check the coolant level in the coolant
recovery tank on the right side of the engine [A].
The coolant recovery tank must be 1/3 full.
Propylene Glycol
Add premixed coolant, 47% water and 53% propylene
glycol to the recovery tank if the coolant level is low.
One gallon and one pint of propylene glycol mixed with
one gallon of water is the correct mixture of coolant to
provide a –34°F (–37°C) freeze protection.
Use a refractometer to check the condition of propylene
glycol in your cooling system.
Ethylene Glycol
Add premixed coolant, 50% water and 50% ethylene
glycol to the recovery tank if the coolant level is low.
Cleaning The Cooling System
Raise the rear grill.
Use air pressure or water pressure to clean the top of the
oil cooler [B].
Raise the oil cooler and clean the top of the radiator [C].
Check cooling system for leaks.
NOTE: The loader is factory filled with propylene
glycol coolant. DO NOT mix propylene glycol
with ethylene glycol.

Always use the correct ratio of water to anti-
freeze.
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 compo-
nents; reduces the boiling point and freeze
protection of the system.
Always add a premixed solution. Adding full
strength concentrated coolant can cause seri-
ous premature engine damage.
