Common Causes
A blown fuse can stop the radiator fan. Fuses protect the electrical system. If a fuse blows, the fan will not work. Check the fuse box for any blown fuses. Replace them with the correct type. Always use the right fuse rating.
A faulty relay can also cause the fan to stop. Relays help control the electrical flow. If a relay fails, it can prevent the fan from turning on. Locate the relay in the fuse box. Test it with a multimeter. Replace if it is faulty.

Initial Inspection
Diagnose the Polaris Ranger radiator fan issue by checking electrical connections and fuses for any visible damage. Ensure the fan motor receives power and spins freely without obstruction.
Visual Check
Check the fan for any visible damage. Look for broken blades or loose wires. Ensure the fan is free from debris. Inspect the radiator for any blockages. Check the fan’s electrical connections. Ensure all connectors are secure. Look for any burnt or frayed wires.
Listen For Sounds
Turn on the Polaris Ranger. Listen for any sounds from the fan area. A working fan should make a humming noise. No sound may indicate a problem. Listen for any clicking or grinding noises. These sounds can signal a mechanical issue. Unusual noises need immediate attention.
Electrical Issues
Polaris Ranger radiator fan not working can lead to overheating issues. Check the fuse, relay, and fan motor for faults. Regular maintenance ensures optimal performance.
Wiring Problems
Wiring problems can stop the radiator fan. Check the wires for any breaks or damage. Loose connections might also cause issues. Ensure all connections are tight and secure. Sometimes, corrosion can affect the wires. Look for rust and clean it up. Replace any damaged wires to avoid future problems.
Battery Health
A weak battery can cause the fan to stop. Check the battery voltage. A healthy battery should read 12.6 volts or more. If the voltage is low, the battery might need charging. Sometimes, batteries need to be replaced if they are too old. Make sure the battery terminals are clean and tight. Dirty or loose terminals can affect performance.

Fan Motor Problems
Experiencing issues with the Polaris Ranger radiator fan not working can lead to engine overheating. Common causes include electrical faults or a broken fan motor. Regular maintenance helps prevent these problems.
Motor Burnout
The fan motor might stop working due to burnout. This means the motor is overheated or worn out. A burnt motor will not turn on. You might smell burnt wires or see smoke. Replacing the motor is the best solution. Regular checks can prevent motor burnout.
Motor Resistance
Motor resistance can cause the fan not to work. This happens if the motor has damaged coils. You can use a multimeter to check resistance. The reading should be within specifications. High resistance means a problem. You may need to replace the motor. Keeping the motor clean helps reduce resistance.
Thermostat Malfunction
A faulty thermostat might cause the Polaris Ranger radiator fan to stop working, leading to engine overheating. Immediate inspection and repair can prevent severe damage and maintain optimal performance.
Testing Thermostat
A faulty thermostat can cause the radiator fan to stop. First, locate the thermostat. It is usually near the engine. Remove it carefully. Boil water in a pot. Place the thermostat in the hot water. Watch if it opens. If it doesn’t open, it is broken. Replace it with a new one.
Replacement Guide
Start by turning off your Polaris Ranger. Let it cool down. Drain the coolant from the radiator. Remove the old thermostat. Clean the area around the thermostat housing. Install the new thermostat. Ensure it is placed correctly. Refill the coolant. Check for any leaks. Start the engine. Monitor the temperature gauge.
Coolant Levels
The radiator fan might not work if the coolant levels are low. Start by locating the coolant reservoir in your Polaris Ranger. The reservoir usually has markings for the minimum and maximum levels. Make sure the coolant is between these marks. If the levels are low, this can cause engine overheating and fan malfunction.
To refill the coolant, first, let the engine cool down. Open the coolant reservoir cap slowly to release any pressure. Use the recommended coolant for your Polaris Ranger. Pour the coolant slowly until it reaches the maximum mark. Close the cap tightly and start the engine. Check if the radiator fan is working properly.
Sensor Failures
The temperature sensor tracks the engine’s heat levels. If it fails, the fan may not activate. Always check if the sensor is dirty or damaged. A faulty sensor can cause the engine to overheat. Replace it quickly to avoid more issues.
The pressure sensor monitors the coolant system’s pressure. A broken sensor can make the fan stop working. Ensure it’s clean and properly connected. If broken, the engine might overheat. Change it to keep your engine safe.
