COOLING SYSTEM
Cooling System Layout and Testing
Cooling System Pressure Test
1. Remove the front rack (see Chapter 9 “Front Rack”).
2. Remove the pressure cap from the radiator and pressure test
the cooling system using a commercially available tester.
3. The system must retain 10 psi for five minutes or longer.
If pressure loss is evident within five minutes, check the
radiator, all cooling system hoses, hose clamps and water
pump seal for leakage.
Radiator Cap Pressure Test
1. Remove radiator pressure cap and test using a cap tester
(commercially available).
2. The radiator cap relief pressure is 13 lbs. Replace cap if it
does not meet this specification.
Recommended Coolant
Use only high quality antifreeze/coolant mixed with distilled
water in a 50/50 or 60/40 ratio, depending on freeze protection
required in your area.
IMPORTANT: Using tap water in the cooling system
will lead to a buildup of deposits which may restrict
coolant flow and reduce heat dissipation, resulting in
possible engine damage. Polaris Premium 60/40
Antifreeze/Coolant is recommended for use in all
cooling systems, and comes pre-mixed and ready to
use.
