GENERAL MAINTENANCE
COOLING SYSTEM
The cooling system in your SHIBAURA Tractor has
been filled with one year lift antifreeze.
To obtain maximum efficiency and service life from
the engine, it must operate at the correct tempera-
ture. This is dependent on the cooling system. The
system should be kept filled with a 50/50 solution of
permanent antifreeze and clear water.
Checking Coolant Level
：
： ：
：
Check the coolant level
between the Low and the Full marks on the coolant
reservoir, Figure
59 , daily or every 10 hours. This
check should be made when the engine is stopped.
It is not necessary to open the radiator cap when
checking the coolant level. But when changing the
coolant, follow the next WARNING to open the ra-
diator cap.
WARNING
： ： ： ：
The cooling system oper-
ates under pressure which is controlled
by the radiator cap. It is dangerous to
remove the cap while the system is hot.
Always cover the cap with a thick cloth
and turn the cap slowly counterclock-
wise to the first stop. Allow all pressure
to escape before removing the cap
completely.
Figure 59 - Radiator Coolant Reservoir
If the cooling system already contains antifreeze,
add only antifreeze solution of the correct water /
antifreeze mixture.
Plain water will dilute the solution and weaken its
protection.
IMPORTANT
： ： ： ：
The radiator is filled with non-amino
type antifreeze. Alcohol-type antifreeze is not rec-
ommended. Do not mix alcohol-type solution with
permanent antifreeze.
Keep the radiator fins clear of chaff or dirt to allow
free passage of air, Figure
61 .
Draining and Flushing the Cooling System
： ： ： ：
Drain and flush the radiator and engine block every
12 months. Refill with a 50/50 mixture of long life
antifreeze, or equivalent, and clear water.
To Drain the System :
1. Remove the radiator cap, Figure
61 on next
page and open the drain valve on both the ra-
diator and the engine block. The radiator drain
valve is located on the bottom right side of the
radiator. The engine block drain valve is located
on the right side of the engine. See Figure
60 .
