  There could be several reasons why your Hisun Offroad Vehicle engine is difficult to start. It could be due to no fuel flow, which requires checking the fuel tank, fuel filter, electric fuel pump, and injector. The ECU can be checked with Motor Scan KF90121, and components replaced if needed. Alternatively, water in the fuel system could be the issue, so ensure the fuel tank cover is tight. In winter, increased oil viscosity can slow the engine revolution, so using oils of different viscosities based on ambient temperatures is recommended. Lastly, a weak battery can cause starting issues. Clean the battery cables and terminals, charge the battery, and in cold weather (below -15?), remove, charge, and store the battery indoors, installing it only when the vehicle will be used.

Why does my Hisun Offroad Vehicle engine overheat?
- N
  Nicholas WilliamsonAug 15, 2025
  Your Hisun Offroad Vehicle engine may overheat due to several reasons. You might be overloading the engine, so shift to a lower gear or reduce the load. Check for a low coolant level and fill the cooling system to the correct level, inspecting the radiator and hoses for loose connections or leaks. The motor-driven fan might not be turning, so check the fuse and the electric system. Also, a dirty radiator core or grille screens can cause overheating, so remove any trash. Finally, a corroded coolant flow route can be the culprit, so flush the cooling system.
