MAINTENANCE AND LUBRICATION
Cooling System (RANGER 4X4, 6X6)
Radiator and Cooling Fan
Always check and clean the screen and radiator fins a t the intervals
outlined in the Periodic Maintenance Chart beginning on page 54. 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.
CAUTION
W ashing the v ehicle with a high-pressure hose could dam age the
radiator fins and impair the r adiator’s effectiveness. Exercise
caution if a high-pressure system is used for washing the vehicle.
Coolant Level
Always check and change the coolant at
the intervals outlined in the Periodic
Maintenance Chart beginning on page 54.
Maintain the coolant level between the
minimum and maximum marks on the
bottle (when the fluid is cool). The
overflow bottle (1) is located in front of
the right front wheel.
1. Position the vehicle on level ground.
2. View the coolant level in the overflow bottle.
3. If the coolant level is below the safe operating range, lift the hood
and locate the overflow bottle lid. Remove the lid and use a funnel
to add coolant through the filler opening. Reinstall the cap.
NOTE: If coolant must be added often, or if the overflow bottle runs
completely dry, there may be a leak in the system. Have the
cooling system inspected by your Polaris dealer.
