    Why is my Kubota KX057-4 engine overheating and the water temperature is in the red zone?
    • T
      Tammy BrownAug 20, 2025
      Several issues could cause overheating. It could be due to a defective water pump seal, a worn or torn V-belt, or a defective thermostat, each requiring replacement. Low coolant level requires refilling to the prescribed level. A clogged radiator grill or fins needs cleaning, while coolant contaminated with rust necessitates replacement and the addition of anti-rust. A defective radiator cap should be replaced, and corroded coolant pipes need cleaning. Continuous full load operation requires reducing the load.
