Changing Anti-freeze and Coolant
A CAUTION
• Before changing
the coolant. be sure to stop the engine .
• Never open
the pressure cap while the engine is running
under heavy loads or immediately after the engine has
stopped.
Otherwise. hot water may spray out, scalding the
operator.
So make it a habit to wait for about 10 minutes before
opening the cap.
1. To drain the used coolant, open the drain cock (2) and
remove
radiator cap (1). The radiator cap must be removed
to completely drain the radiator.
2. Radiator should be filled with 50/50 part of anti-freeze and
water at all times as recommended by the anti-freeze
manufacturer. The anti-freeze contains a corrosion inhibitor
and will allow a higher operating temperature in the
radiator during the hot season.
3. Be sure to dose the pressure cap securely. If the cap is loose
or improperly closed, water may leak out and the engine
could overheat.
4. Don't use an anti-freeze and scale inhibitor at the same time.

Drain Cock
(Anti-freeze)
Ifthe cooling water freezes, the engine cylinder and radiator
may crack. In cold weather before the temperature drops
below O°C (32°F), drain out the water or add a proper amount
of anti-freeze when the machine is shut down.
• There are two types of anti-freeze solutions, permanent type
(PT) and semi-permanent type (SPT). For the Kubota Engine,
be sure
to use the permanent type.
•
When anti-freeze is used for the first time, fill and drain
dean water two or three times so as to completely clean the
inside of the radiator.
• Mix the anti-freeze and the water, then pour the mixture
into the radiator.
• When the cooling water mixed with anti-freeze decreases
due to evaporation, replenish with water only. If loss has
been
due to leaking, add water and anti-freeze mixture with
the same mix ratio as the original preparation.
• Anti-freeze solutions absorb moisture, so be sure to securely
dose
the container after use.
•
Anti-freeze and coolant should be changed every year.
• Do
not use an anti-freeze and a scale inhibitor at the same
time. This may cause sludge to form adversely affecting the
engine parts.
Cleaning
Cooling System
1. The cooling system should be cleaned on the following
occasions:
• Everyone year service.
•
When adding anti-freeze solution.
• When changing from water containing anti-freeze to pure
water.
2. When cleaning the cooling system, KUBOTA Scale Inhibitor
No.20 or its equivalent, is recommended to effectively wash
away scale
build up.
