Coolant (Antifreeze/Summer Coolant/Water)
KUBOTA recommends antifreeze/summer coolant for use
in their engines, which can be purchased in concentrate (and
mixed with 50% demineralized water) or pre-diluted. See
the KUBOTA Engine Owner's Manual for further details.
WARNING - BURN HAZARDS
If adding coolant/antifreeze mix to the
radiator, DO NOT remove the radiator
cap until the unit has completely cooled.
The possibility of hot! coolant exists
which can cause severe burns.
Day-to-day addition of coolant is done from the recovery
tank. When adding coolant to the radiator, DO NOT remove
the radiator cap until the unit has completely cooled. See
Table 9 for engine, radiator, and recovery tank coolant
capacities. Make sure the coolant level in the recovery tank
is always between the "H" and the "L" markings.

DCA10SPX4/DCA10SPXU4 — SETUP
Cleaning the Radiator
The engine may overheat if the radiator fins become
overloaded with dust or debris. Periodically clean the radiator
fins with compressed air. Cleaning inside the machine is
dangerous, so clean only with the engine turned off and the
negative battery terminal disconnected.
Air Cleaner
Periodic cleaning/replacement is necessary. Inspect it in
accordance with the KUBOTA Engine Owner's Manual.
Fan Belt Tension
A slack fan belt may contribute to overheating, or to
insufficient charging of the battery. Inspect the fan belt for
damage and wear and adjust it in accordance with the
KUBOTA Engine Owner's Manual.
The fan belt tension is proper if the fan belt bends 10 to 15
mm (Figure 18) when depressed with the thumb as shown
below.
