| Engine overheating condition and remedies | Overheating occurs when coolant temperature is near or above boiling point. If warning lamp lights or steam squirts, stop engine, idle for 5 min, then check: coolant level/leaks, cooling air inlet/outlet obstacles, radiator fins/tube dirt, fan belt looseness, radiator water pipe clogging. Other causes include: insufficient engine oil, broken/elongated fan belt, insufficient coolant, excessive antifreeze concentration, corroded radiator parts, defective fan/radiator/cap, defective thermostat/sensor, overload running, defective head gasket/water leakage, unsuitable fuel. | p. 29 |
| Engine Oil Quantity | 13.2 L (3.49 U.S. gal.) | p. 26 |
Kubota V3300–V3800 Series Common Problems This Manual Covers
Hard starting after long storage
Engines that sit for months often crank without firing because fuel is not primed and oil has not reached all parts. The starting and cold-weather procedures cover priming and correct cranking before normal operation.
Manual Section: Operating the Engine p. 14Oil pressure warning lamp stays on
If the oil pressure lamp lights during operation or will not go off above 1000 rpm, the manual says to stop immediately and check oil level, wiring, the lubricating system, and the pressure switch.
Manual Section: Operating the Engine p. 14Overheating and coolant temperature rise
Low coolant, a clogged radiator, wrong antifreeze mix, or restricted airflow drive the temperature up. The troubleshooting section lists the checks to run before more damage occurs.
Manual Section: Troubleshooting p. 34Turbocharger trouble after heavy load
Shutting a turbocharged engine down right after full-load work causes heat soak and turbo damage. The stopping procedure calls for idling before shutoff.
Manual Section: Operating the Engine p. 14Air cleaner and filter service due
Restricted air cleaner elements and aged intake tubes cause power loss and rough running. Periodic service covers cleaning intervals and element replacement.
Manual Section: Periodic Service p. 22Fan belt tension out of range
A loose or worn fan belt leads to poor charging and cooling. Periodic service gives the deflection check and adjustment steps.
Manual Section: Periodic Service p. 22Frequently Asked Questions
