  If your Kubota Engine suddenly stops, first check the fuel tank and refill if necessary, also check the fuel system for air or leaks. A bad nozzle can also cause this, so replace it with a new one if needed. Additionally, moving parts may be overheated due to a shortage of lubrication oil or improper lubrication. Check the engine oil level with the oil level gauge and inspect the lubricating oil system. Replace the oil filter cartridge every two oil changes.

How to start a Kubota V1505-E3BG that is difficult to start?
- B
  Bradley BoydAug 17, 2025
  If you're finding it difficult to start your Kubota Engine, begin by checking the fuel tank and fuel filter for any water, dirt, or impurities, cleaning the filter with kerosene. Air or water in the fuel system can also be the culprit; check for loose fuel line couplings or cap nuts and eliminate air from the fuel system by loosening the joint bolt stop fuel filter and air vent screws of fuel injection pump. In cold weather, thick engine oil can slow cranking, so change the oil grade according to the temperature. Lastly, a discharged battery can prevent the engine from cranking, so charge the battery and, in winter, remove it for indoor storage, installing it only when needed.

  To address Kubota Engine overheating, first, check the oil and coolant levels and replenish if needed. Inspect the fan belt for damage or looseness and replace or adjust it. Clean any dust from the radiator net or fins. If the issue persists, consider that the excessive antifreeze concentration may be the cause, so add only water or switch to the specified coolant mixture. Other potential causes include a defective fan, radiator, radiator cap, thermostat, temperature gauge, or sensor, which would require replacement. Overload running can also cause overheating, so reduce the load. Finally, a defective head gasket or water leakage or unsuitable fuel may be the cause, requiring parts replacement or using the specified fuel.
