  Your Polaris Offroad Vehicle might be overheating due to several reasons. It could be caused by low coolant level, air in the cooling system, or using the wrong type/mix of coolant. A faulty pressure cap or system leaks, a restricted cooling system (due to mud or debris), a lean fuel mixture, a weak fuel pump, or electrical malfunctions can also lead to overheating. Other potential causes include water pump failure, a faulty thermistor, a cooling fan not working correctly, misadjusted ignition timing, low oil level, using the wrong spark plug heat range, a faulty hot light circuit, or a thermostat stuck closed. Check these components and systems to identify the issue. For example, top off the coolant level or bleed air from the cooling system.
