3.1.5 Engine Coolant Level Check
DO NOT STOP ENGINE SUDDENLY, IDLE ENGINE FOR 5 MINUTES BEFORE
STOPPING.
WORK SHOULD BE CARRIED OUT AFTER LETTING THE ENGINE AND RADIATOR
COOL OFF COMPLETELY (A MINIMUM OF 30 MINUTES AFTER STOPPING
ENGINE).
DO NOT REMOVE RADIATOR CAP WHILST ENGINE COOLANT IS HOT AND
PRESSURISED. WHEN COOL TO TOUCH, ROTATE CAP TO THE FIRST STOP TO
ALLOW EXCESS PRESSURE TO ESCAPE, THEN REMOVE CAP COMPLETELY.
IF OVERHEATING SHOULD OCCUR, STEAM MAY GUSH FROM THE RADIATOR OR
RESERVE TANK RESULTING IN SEVERE BURNS.
1) Remove the radiator cap after the engine has
completely cooled. Ensure the coolant level
reaches the supply port.
2) Ensure coolant level is sufficient on the
reserve tank. The level should be between
the full and low marks.
3) Ensure both drain plugs are installed; one to
the lower part of the radiator (2) and the
other is on the side of the crank case (1).
4) If coolant levels are low, top-up using the
correct specification fluid. See section 2.4.5.
Important;
• If the radiator cap has to be removed follow the caution label and securely tighten the cap.
• If coolant should leak, consult your local Kubota dealership.
• Make sure contaminated or sea water does not enter the coolant system.
• Use clean, fresh water with the correct amount of anti-freeze. See section 2.4.5.
• Do not refill reserve tank with coolant higher than the "FULL" level mark.
• Be sure to close the radiator cap securely. If the cap is loose or improperly closed, coolant may leak
out and quickly decrease the coolant level.
