Cooling System - Polaris BRUTUS Owner's Manual

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 sys-
tem is purging itself of trapped air. Observe coolant levels and
maintain as recommended by adding coolant to the overflow
bottle.
Adding or Changing Coolant
To ensure that the coolant maintains its ability to protect the
engine, we recommend that the system be completely drained
every two years and a fresh mixture of antifreeze and water
added.
NOTICE: Do not mix different types of coolant in the cooling system
when adding coolant. Mixing types can result in damage to
the cooling system.
POLARIS recommends the use of POLARIS Premium 60/40
anti-freeze/coolant or a 50/50 mixture of high quality alumi-
num compatible anti-freeze/coolant and distilled water.
POLARIS Premium 60/40 is already premixed and ready to
use. Do not dilute with water.
Always follow the manufacturer's mixing recommendations
for the freeze protection required in your area.
Any time the cooling system has been drained for maintenance
or repair, replace the coolant. If the recovery bottle has run dry,
the level in the radiator should be inspected. Add coolant as
needed.
Radiator and Cooling Fan
Always check and clean the screen and radiator fins at the
intervals outlined in the Periodic Maintenance Chart beginning
on page 78. 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 radia-
tor air flow can lead to overheating and consequent engine
damage.
NOTICE: Washing the vehicle with a high-pressure hose could
damage the radiator fins and impair the radiator's
effectiveness. Using a high-pressure system is not
recommended.
