antifreeze.
Always use a 50/50 mix of antifreeze and clean soft
water in Kubota engines.
Consult your local Kubota Dealer concerning coolant
for extreme conditions.
1. Coolant comes in several types. Use ethylene
glycol (EG) type for this engine.
2. Before employing the 50/50 mix, 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 coolant
Premix 50 % antifreeze 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.
IMPORTANT :
• When mixing the antifreeze with water, the
antifreeze mixing ratio is 50 %.

5. Adding the coolant
a. Add only water if the coolant level reduces in
the cooling system by evaporation.
b. If there is a mixture leak, add the antifreeze of

Removal of ash
The longer the DPF operates, the more ash (burnt
residue) is collected in the filter. Too much ash build-up
adversely affects the DPF performance.
