What to do if my Kubota Utility Vehicle engine overheats?
- J
  John CallahanAug 19, 2025
  If your Kubota Utility Vehicle engine overheats, several factors could be responsible. The engine might be overloaded, so shift to a lower gear or reduce the load. A low coolant level could also be the cause, so fill the cooling system to the correct level and inspect the radiator and hoses for leaks. Check if the motor-driven fan is functioning and ensure the fuse isn't blown, and inspect the electrical system. Remove any trash from a dirty radiator core or grille screens. Finally, flush the cooling system if the coolant flow route is corroded.

  If the HST oil in your Kubota Utility Vehicle overheats, it could be due to several reasons. The HST might be overloaded, so reduce the load. Check for a low oil level and fill it to the correct level. Remove any trash from a dirty oil cooler core or screens. Inspect the oil cooling system if the oil flow route is corroded. Lastly, ensure the hydraulic lever is not positioned at the end of its stroke; set it to the "NEUTRAL" ("OFF") position.

How to troubleshoot a Kubota Utility Vehicle engine that is difficult to start?
- J
  Jaime CardenasAug 23, 2025
  If your Kubota Utility Vehicle's engine is hard to start or refuses to start, several factors could be at play. First, check the fuel tank and fuel filter, replacing the filter if needed, to ensure adequate fuel flow. Air or water in the fuel system can also be a culprit; ensure the fuel line coupler bolt and nut are tight, and bleed the fuel system. In cold weather, use appropriate oil viscosities to combat increased oil viscosity. Weak batteries can hinder starting, so clean the battery cables and terminals, charge the battery, and consider storing the battery indoors in cold weather, installing it only when needed.

Why does my Kubota RTV-X900G Utility Vehicle have insufficient engine power?
- A
  Aaron MilesAug 26, 2025
  If your Kubota Utility Vehicle has insufficient engine power, the issue might stem from insufficient or dirty fuel, so check the fuel system. Another potential cause is a clogged air cleaner. If the air cleaner is clogged, clean or replace the element.

Why are the exhaust fumes from my Kubota RTV-X900G colored?
- C
  Connor MillsAug 28, 2025
  Colored exhaust fumes from your Kubota Utility Vehicle indicate potential issues. Black smoke suggests poor fuel quality, too much oil, or a clogged air cleaner. Change the fuel and fuel filter, check the oil level, and clean or replace the air filter element. Blue-white smoke may indicate fuel in the exhaust muffler, injection nozzle trouble or poor fuel quality. Try heating the muffler by applying a load to the engine, check the injection nozzle, and change the fuel and fuel filter.

Why does the starter not function on my Kubota Utility Vehicle?
- M
  matthewsmithSep 3, 2025
  If the starter on your Kubota Utility Vehicle isn't functioning, it could be due to several reasons. The battery might be overused, so charge it sufficiently. Check for a poor terminal connection, and if found, clean the terminal and tighten it securely. It's also possible that the battery life has expired, so replace the battery if needed.
