Polaris Sportsman 570 Overheating- Reason and Solution in Details
As we mentioned earlier, there are quite a few reasons that cause ATVs to overheat. Solving these problems as soon as they appear is a must to avoid severe accidents or injuries. Let us guide you through the details of the reasons and how you can fix them easily.
1. Faulty Fan Motor
One of the most common reasons why an ATV overheats is a bad fan motor. As the vehicle moves along the terrain, the engine heats up and requires cooling. If the fan motor is faulty, then it will not be able to function properly. Thus, the overall temperature will continue to rise, causing overheating.
Solution
The solution to this problem is extremely simple. Check the cooling fan in the vehicle and make sure that it is working properly. Replace the engine or replace it with a new one if required. You can install in place of the old one.
2. Low Coolant Level
Each and every vehicle in the market requires coolant in the radiator. The purpose of relying on coolant is to make sure that the engine cools down properly. However, there is a specific amount required in each radiator, and a low coolant level will result in overheating.
Solution
Examine the radiator and make sure that the coolant is at the right level. Add more to the radiator until it reaches the right amount. This will make sure that the vehicle does not heat up more than normal.
3. Blocked Radiator
Another primary reason behind excessive heating is a blocked radiator. Oftentimes, the radiator gets blocked due to the accumulation of dirt, dust, debris, and so on. When the radiator is blocked, it will not be able to cool the ATV properly, and the vehicle will overheat significantly.
Solution
Check the radiator and see whether it is clogged or not. Conduct a radiator flush by cleaning the entire system properly. This will cause the system to be clear of grime, dirt, dust, and all other pollutants. And the radiator will provide efficient performance.
4. Faulty Thermostat
ATVs come with a thermostat in the cooling system, which helps the engine to maintain the right temperature. If the thermostat is malfunctioning or stops working altogether, then it will not be able to perform its work correctly. This will result in malfunctioning temperature control and result in excessive heating of the engine.
Solution
Inspect the vehicle’s thermostat and ensure it is in proper working condition. If the thermostat is faulty, repair it and ensure that it holds the temperature properly. However, if repairing does not work, then replace the system with a new one.

5. Wrong Coolant Mixture
Every car relies on a specific type, formulation, and concentration of coolant. Using the wrong mixture or type of coolant will prevent the radiator from cooling the ATV properly. Not only that, but it will affect the vehicle’s overall health over time.
Solution
Take out the user manual of the Polaris Sportsman 570 and ensure that you are using the right mixture of coolant. If the one you are using is wrong, then flush and throw out the entire fluid properly. Fill the radiator up to the correct level with the right type and concentration of liquid.
6. Bad Water Pump
The water pump is an important vehicle component. This pump pushes hot coolant from the engine of the ATV through the cooling system. And the cooled coolant then travels back to the engine. But if the water pump does not work, then the hot coolant will remain trapped in the engine, causing overheating.
Solution
Scan the entire system properly and ensure that the water pump is not malfunctioning. Repair the water pump and ensure that there are no leaks or problems. If the pump does not work after repair, the best option is to replace it.
The Consequences Of Overheating In Polaris Sportsman 570
When the Polaris Sportsman 570 overheats, the owners encounter quite a few consequences. Overheating causes the engine to heat up more than usual and affects the overall health of the ATV. It also results in power loss, fluid leaks, and so on.
