  Robin ThompsonSep 7, 2025
  A Polaris Offroad Vehicle engine can overheat due to debris lodged in the screen. Clean the screen to resolve this. Additionally, a plugged radiator can cause overheating. Use a garden hose to flush any debris from the radiator fins, but avoid using high-pressure washers, as they can deform the fins and reduce cooling efficiency.
