Radiator Coolant Level - Polaris RANGER 400 Owner's Manual

Cooling System
Overflow Bottle Coolant Level
Always check and change the coolant at the intervals outlined in the Periodic Maintenance
Chart beginning on page 52. Maintain the coolant level between the minimum and maximum
marks on the bottle (when the fluid is cool).
The overflow bottle is located in
front of the right front wheel.
1. Position the vehicle on a level
surface.
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 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. Have the cooling system inspected by your POLARIS dealer.

Radiator Coolant Level

Always check and clean the screen and radiator fins at the intervals outlined in the Periodic
Maintenance Chart beginning on page 52. 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. Lift the hood.
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.
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. See your dealer for the correct replacement part.
