The RANGER XP 1000 EPS NorthStar Edition and RANGER CREW XP 1000 EPS NorthStar Edition feature factory-installed heating and air conditioning. For more information, read 2017-2024 RANGER XP 1000 NorthStar Air Conditioning Maintenance.
Cooling System
The engine coolant level is controlled or maintained by the recovery system. The recovery system components are the overflow bottle, radiator filler neck, radiator pressure cap and connecting hose.
As coolant operating temperature increases, the expanding (heated) excess coolant is forced out of the radiator, past the pressure cap and into the overflow bottle. As engine coolant temperature decreases, the contracting (cooled) coolant is drawn back up from the tank, past the pressure cap and into the radiator.
Some coolant level drop on new vehicles is normal as the system is purging itself of trapped air. Observe coolant levels and maintain as recommended by adding coolant to the overflow bottle.
Notice: Washing the vehicle with a high-pressure hose could damage the radiator fins and impair the radiator's effectiveness. If you use a pressure washer to clean your vehicle, do not aim the nozzle at sensitive components. The maximum pressure should not exceed 3000 PSI, 2.5 GPM with a 40° pressure washer nozzle. Make sure to keep the pressure washer nozzle 2 feet away from the vehicle. Use extreme caution if you choose to use a high-pressure hose.
Adding or Changing Coolant
Polaris recommends the use of Polaris Antifreeze 50/50 Premix. This antifreeze is already premixed and ready to use. Do not dilute with water. Polaris Antifreeze 50/50 Premix is part number 2880513 for one gallon (3.78 L).
To ensure that the coolant maintains its ability to protect the engine, we recommend that the system be completely drained every five years and fresh Antifreeze 50/50 Premix added.
Any time the cooling system has been drained for maintenance or repair, replace the coolant with fresh Antifreeze 50/50 Premix. If the recovery bottle has run dry, the level in the radiator should be inspected. Add coolant as needed; see instructions below.
Radiator and Cooling Fan
Always check and clean the screen and radiator fins at the intervals outlined in the Periodic Maintenance Chart in your Owner's Manual. Do not obstruct or deflect air flow through the radiator by installing unauthorized accessories in front of the radiator or behind the cooling fan. Interference with the radiator air flow can lead to overheating and consequent engine damage.

Radiator Coolant Level Inspection
Always check and clean the screen and radiator fins at the intervals outlined in the Periodic Maintenance Chart in your Owner's Manual.
Do not obstruct or deflect air flow through the radiator by installing unauthorized accessories in front of the radiator or behind the cooling fan. Interference with the radiator air flow can lead to overheating and, consequentially, engine damage.
1. On model year 2018 and newer vehicles, lift the hood. On model year 2017 vehicles, remove the hood by rotating the two hood latches a quarter turn and lifting away from the vehicle.
Caution: Escaping steam can cause burns. Never remove the pressure cap while the engine is warm or hot. Always allow the engine to cool before removing the pressure cap.
2. Slowly remove the radiator cap (1).
3. View the coolant level through the opening.
4. Use a funnel and slowly add coolant as needed. Tip: This procedure is required only if the cooling system has been drained for maintenance and/or repair. But if the overflow bottle has run dry, the level in the radiator should also be inspected.
5. Reinstall the pressure cap. Use of a non-standard pressure cap will not allow the recovery system to function properly. Your Polaris Dealer can provide the correct replacement part.
Overflow Bottle Coolant Level
Always check and change the coolant at the intervals outlined in the Periodic Maintenance Chart in your Owner's Manual. Maintain the coolant level between the minimum and maximum marks on the bottle (when the fluid is cool).
1. Position the vehicle on a level surface and place the transmission in PARK.
2. On model year 2018 and newer vehicles, lift the hood. On model year 2017 vehicles, remove the hood. To remove the hood, rotate the hood latches a quarter turn and lift the hood away from the vehicle.
3. View the coolant level in the overflow bottle (2).
3. If the coolant level is below the safe operating range, lift the hood and locate the overflow bottle lid. Remove the cap and use a funnel to add coolant through the filler opening. Reinstall the cap. Tip: If coolant must be added often or if the overflow bottle runs completely dry, there may be a leak in the system. Your Polaris Dealer can inspect the cooling system.
Only licensed and certified professionals are allowed to check and maintain air conditioning refrigerant levels. If you need service performed on your air conditioning system, see your Polaris Dealer. To find a Polaris Dealer near you, use the Dealer Locator.
