Anti-Freeze - Kubota STV32 Operator's Manual

72 PERIODIC SERVICE
(1) Radiator cap (A) "FULL"
(2) Recovery tank (B) "LOW"
A Do not start engine without coolant.
A Use clean, fresh soft water and anti-freeze to fill the
radiator and recovery tank.
A When the anti-freeze is mixed with water, the anti-
freeze mixing ratio must be less than 50%.
A Securely tighten radiator cap. If the cap is loose or
improperly fitted, water may leak out and the engine
could overheat.
A On cab type machines, fresh water circulates through
the heater. This means that one more liter or so of
fresh water is required.
In changing fresh water, pour fresh water up to the
filler port of the reserve tank. Turn ON the heater (shift
the temperature control lever toward WARM), and run
the engine for a while in order to warm fresh water.
Then stop the engine.
When fresh water has cooled down, some of the fresh
water in the reserve tank is sucked. Now the reserve
tank is appropriately filled with fresh water.
BAnti-Freeze
To avoid personal injury:
A When using antifreeze, put on some protection
such as rubber gloves (Antifreeze contains
poison.).
A If it is swallowed, seek immediate medical help.
Do NOT make a person throw up unless told to
do so by poison control or a health care
professional. Use standard first aid and CPR
for signs of shock or cardiac arrest. Call your
local Poison Control Center or your local
emergency number for further assistance.
A When antifreeze comes in contact with the skin
or clothing, wash it off immediately.
A Do not mix different types of Antifreeze.
The mixture can produce chemical reaction
causing harmful substances.
A Antifreeze is extremely
explosive under certain conditions. Keep fire
and children away from antifreeze.
A When draining fluids from the engine, place
some container underneath the engine body.
A Do not pour waste onto the grounds, down a
drain, or into any water source.
A Also, observe the relevant environmental
protection regulations when disposing of
antifreeze.
Always use a 50/50 mix of long-life coolant and clean soft
water in KUBOTA engines.
Consult your local KUBOTA Dealer concerning coolant for
extreme conditions.
1. Long-life coolant (hereafter LLC) comes in several
types. Use ethylene glycol (EG) type for this engine.
2. Before employing LLC-mixed cooling water, fill the
radiator with fresh water and empty it again.
Repeat this procedure 2 or 3 times to clean up the
inside.
3. Mixing the LLC
Premix 50% LLC with 50% clean soft water. When
mixing, stir it up well, and then fill into the radiator.
4. The procedure for the mixing of water and antifreeze
differs according to the make of the antifreeze and the
ambient temperature. Refer to SAE J1034 standard,
more specifically also to SAE J814c.

A higher boiling point is obtained by using a radiator
pressure cap which permits the development of
pressure within the cooling system.
