What to do if my Hisun Utility Vehicle engine overheats?

  Ryan JimenezAug 13, 2025
  If your engine overheats, several potential causes need to be investigated. First, check if the engine is overloaded and shift to a lower gear or reduce the load. Ensure the coolant level is correct and inspect the radiator and hoses for leaks. Verify that the motor-driven fan is functioning and that its fuse is intact, and check the electrical system. Clear any debris from the radiator core or grille screens. Finally, consider flushing the cooling system if the coolant flow route is corroded.

Why is my Hisun Utility Vehicle engine difficult to start?
- A
  Anna AndradeAug 23, 2025
  Several factors can cause this issue. It could be due to no fuel flow, which requires checking the fuel tank, fuel filter, electric fuel pump, injector, and ECU. Water in the fuel system could also be the culprit, so ensure the fuel tank cover is tight. In winter, increased oil viscosity can slow the engine revolution; using oils of different viscosities depending on ambient temperatures is recommended. Lastly, a weak battery can prevent the engine from turning over quickly enough. Clean the battery cables and terminals, charge the battery, and in cold weather, remove the battery, charge it indoors, and install it only when the vehicle is in use.
