3.8 Coolant
Be sure engine is turned off, and allowed to cool.
The radiator is located under the engine cover, behind the engine.
Overheating may occur if the radiator is not cleaned daily. Brush out and clean the radia-
tor and hood grills daily to prevent overheating.
Check the coolant level in the reserve tank (located to the left front of the radiator). The
coolant level should maintain a level of 3/4 full at all times. If the coolant level is low, add
coolant prior to operation. If the coolant appears excessively contaminated or diluted,
change the coolant prior to operation. Consult the Kubota Diesel Engine Operator’s Man-
ual located in the back of this manual for proper coolant types and mixtures.
Check the entire coolant system for any leaks. Areas to inspect include the radiator, over-
flow tank, all hoses, clamps, and fittings, the entire engine area, and under the engine. If
any leaks are discovered, allow ample time for coolant to cool. Repair or replace the
defective parts and re-fill the coolant system before operating the Articulator.
The radiator is pressurized!
NEVER check the coolant while the engine is running!
COOLANT IS HOT! Always allow ample time for coolant to cool before
checking, changing, or repairing leaks!
Clean Radiator Daily! Overheating may occur if radiator is not cleaned
daily.
Brush out and clean radiator and hood grills daily to prevent
overheating!!
Be sure the coolant system is filled to the proper level, the coolant is
mixed properly, and is in good condition!
ALWAYS check to be sure there are no coolant leaks before operating
the Articulator!
Incorrect mixture, inadequate coolant level, poor condition, or leaks of
any kind can cause severe engine damage!
