  Thomas RodriguezAug 15, 2025
  If your Hisun Utility Vehicle engine is overheating, it could be due to several factors. First, check if the engine is overloaded and shift to a lower gear or reduce the load. Ensure the coolant level is adequate and inspect the radiator and hoses for leaks. Verify that the motor-driven fan is functioning and that its fuse isn't blown, and check the electric system. Also, make sure the radiator core or grille screens are free from debris. If the coolant flow route is corroded, flush the cooling system.

  If your Hisun Utility Vehicle has less power, check if the parking brake is engaged and loosen the lay-up rod if necessary. For non-full uncoupling of the disc brake, or if there is CVT transmission sliding, contact the distributor. If sliding is the issue, try removing the grease from the clutch or replacing the CVT transmission belt or the clutch.

What causes non agility for gearshift in Hisun HS394-2 Utility Vehicle?
- K
  Kevin CooperSep 4, 2025
  Non agility for gearshift in Hisun Utility Vehicle can be caused by several factors, including high idling speed of the engine. In this case, replace the throttle cable, throttle petal, or the throttle. High rotary speed for clutch connection can also be a factor, so replace the junior clutch spring or the primary clutch. If there is non good adjust for gearshift stay wire, put the gearshift rod into the position of “N”, put the gearshift arm of engine into ”N”, adjust the stay wire and the bolt, and lock tightly. Gear abrasion can also cause this issue, so replace the gears.
