Radiator Inspection / Cleaning
1. Check radiator air passages for restrictions or
damage.
2. Carefully straighten any bent radiator fins.
3. Remove any obstructions with low pressure
compressed air or low pressure water.
Coolant Drain / Fill
1. Remove the front hood.
2. Slowly remove the pressure cap to relieve any cooling
system pressure.
3. Place a suitable drain pan underneath the radiator
fitting on the front right side of the vehicle.
4. Drain the coolant from the radiator by removing the
lower coolant hose from the radiator as shown.
5. Allow coolant to drain completely. Properly dispose of
the used coolant.
6. Reinstall coolant hose and reposition the spring
clamp.
7. Remove the pressure cap. Using a funnel, add the
recommended coolant to the top of the filler neck and
fill the recovery bottle to the MAX level.
8. Refer to “Cooling System Bleeding Procedure”
provided in Chapter 3.
Washing the vehicle with a high-pressure
washer could damage the radiator fins and
impair the radiators effectiveness. Use of a high-
pressure washer is not recommended.
Never drain the coolant when the engine and
radiator are warm or hot. Hot coolant can cause
severe burns. Allow engine and radiator to cool.
Recommended Coolant:
Polaris Premium Pre-Mixed Antifreeze
