Replacing Fan Belt - Kubota D1803-CR-E4 Workshop Manual

CHECK AND MAINTENANCE
6.Check points of every 500 hours
12. Check the coolant level of radiator and reserve tank
(4) and add coolant if necessary.
Anti-freeze
NOTE
• There are 2 types of anti-freeze available:
use the permanent type (PT) for this engine.
• When you add anti-freeze for the first time,
flush the water jacket and radiator interior
with clean, soft water several times.
• The brand of the anti-freeze and the ambient
temperature have an effect on the procedure
to mix water and anti-freeze.
Refer to the SAE J1034 standard, especially
to the SAE J814c.
• Mix the anti-freeze with clean, soft water,
and then fill into the radiator.
IMPORTANT
• Make sure that when you mix the anti-freeze
and water, the ratio of anti-freeze is less than
50%.

* At 1.01 × 100000 Pa (760 mmHg) pressure (atmospheric). Use
a radiator pressure cap that lets the pressure collect in the
cooling system to get a higher boiling point.
NOTE
• The above data is the industrial standards
that shows the minimum glycol content
necessary in the concentrated anti-freeze.
• When the coolant level decreases because
of evaporation, add clean, soft water only to
keep the anti-freeze mixing ratio less than
50%.
If there is a leakage, add anti-freeze and
clean, soft water in the specified mixing
ratio.
• The anti-freeze absorbs moisture. Keep new
anti-freeze in a tightly sealed container.
• Do not use the radiator cleaning agents after
you add anti-freeze to the coolant.
Anti-freeze contains an anti-corrosive agent,
which reacts with the radiator cleaning
agent to make sludge and cause damages to
the engine parts.
