Cooling Systems
Important:
Check the cooling system every day to prevent overheating, loss of
performance or engine damage.
Checking Coolant Level
1. Open the rear door. Check the coolant
level in the coolant recovery tank on
the inside of the rear door. The coolant
recovery tank must be 1/3 to 1/2 full
with a cold engine and 2/3 to 3/4 full
with a hot engine.
2.
Allow the coolant to cool. Do not
remove the cap when the coolant is
hot. Serious burns may occur.
3.
Add premixed coolant, 50% water and
50% ethylene glycol, to the recovery
tank if the coolant level is low.
Cleaning Cooling System
1. Park the loader on a level surface,
lower the lift arm and stop the engine.
Allow the engine to cool.
2.
Open the rear door. Lift the engine cover.
3.
Clean the radiator and oil cooler by blowing through the fins with high pres-
sure water or air.
Note:
The radiator can be tipped out for cleaning by loosening and rotating the
over-center links on each side. This will also help in cleaning the oil cooler.
Draining/Flushing Cooling System
1. Open the rear door. Lift the engine cover.
2.
Slowly remove the radiator cap, allowing pressure to dispel before removing
completely.
Liquid cooling systems build up pressure as the
engine becomes hot. Before removing the radi-
ator cap, stop the engine and let the system cool. Remove the radiator
cap only after the coolant has cooled. Remove the cap slowly or
severe burns may result.
3.
Remove the drain plug and drain the coolant into a suitable container.
4.
Replace the drain plug.
Note:
Protect the cooling system by adding premixed 50% water and 50% ethy-
lene glycol to the system. This mixture will protect the cooling system to -34°F
(-36°C).
