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 anti-freeze
differs according to the make of the anti-freeze and the
ambient temperature. Refer to SAE J1034 standard,
more specifically also to SAE J814c.
A
When mixing the anti-freeze with water, the anti-freeze
mixing ratio is 50%.
* At 1.013 x 10 Pa (760 mmHg) pressure (atmospheric).
A higher boiling point is obtained by using a radiator
pressure cap which permits the development of pressure
within the cooling system.
5. Adding the LLC
(1) Add only water if the coolant level reduces in the
cooling system by evaporation.
(2) If there is a mixture leak, add the LLC of the same
manufacturer and type in the mixing ratio 50%.
6. When the LLC is mixed, do not employ any radiator
cleaning agent. The LLC contains anti-corrosive
agent. If mixed with the cleaning agent, sludge may
build up, adversely affecting the engine parts.
7. Kubota's genuine long-life coolant has a service life of
2 years. Be sure to change the coolant every 2000
hours or every 2 years whichever comes faster.

The above data represent industry standards that
necessitate a minimum glycol content in the
concentrated anti-freeze.

Checking Fuel Lines
If you feel you are unable to make the following service
correctly and safely, contact your local KUBOTA Dealer.
(See "Checking Fuel Filter" in "EVERY 100 HOURS" in

B
Checking Radiator Hose and Clamp
If you feel you are unable to make the following service
correctly and safely, contact your local KUBOTA Dealer.
To avoid serious injury or death:
A
Be sure to stop the engine and remove the key
before checking radiator hose and clamps.
1. If hose clamps are loose or water leaks, tighten clamps
securely.
2. Replace hoses and tighten hose clamps securely. If
radiator hoses are swollen, hardened or cracked, then
replace them immediately.
