A If the radiator cap has to be removed, proceed with
caution and securely retighten the cap.
A If coolant is leaking, consult your local KUBOTA
Dealer.
A Make sure that muddy or sea water is not used in the
radiator.
A Use clean, fresh water and 50% anti-freeze to fill the
recovery tank.
A Do not refill recovery tank with coolant over the
"FULL" level mark.
A Be sure to close the radiator cap securely. If the cap is
loose or improperly closed, coolant may leak out and
decrease the level quickly.
A When coolant is added, coolant level may drop the
first time the engine is started. Stop the engine, and
add coolant if necessary.
BChanging Coolant
1. To drain coolant, always remove both drain plugs and
simultaneously open the radiator cap as well. With the
radiator cap kept closed, the coolant will not drain
completely. Dispose of used coolant properly.
2. Remove the overflow pipe of the radiator pressure cap
to drain the recovery tank.
3. Prescribed coolant volume
L
4. An improperly tightened radiator cap or a gap between
the cap and the seat increases loss of coolant.
5. Coolant (Radiator cleaner and anti-freeze)
BRemedies for Rapid Coolant Loss
1. Check for dust and dirt between the radiator fins and
cooling tube. Clean the fins and the tubes as if
necessary.
2. Check the tension of the fan belt. If loose, tighten it
securely.
3. Check the internal blockage in the radiator cooling
tubes. If scale forms in the tubes, clean with the scale
inhibitor or its equivalent.
