General Maintenance
Exhaust System
Check the exhaust system for wear or damage at approximately 2000
miles (3200 km). To inspect, allow the engine and exhaust system to
cool completely. Open the hood and inspect the muffler and pipes for
cracks or damage. Check for weak or missing retaining springs or
damper/support grommets.
Engine Cooling - Liquid Cooled Models
The cooling system on liquid cooled models consists of the following
major components:
• Coolant bottle
• Water pump
• Cylinders
• Heads
• Inlet and outlet manifolds
• Pressure cap
• Heat exchangers
Coolant
The coolant supplied in the system is a 60/40 mixture of ethylene-glycol
and distilled water. This mixture provides protection against freezing.
Contact your dealer if greater protection is required.
Use Premium 60/40 anti-freeze coolant, which is already premixed and
ready to use. Do not dilute with water. Never exceed a 60% antifreeze/
40% water mixture. See page 132 for the part numbers of Polaris prod-
ucts.
NOTE: Never add tap water to the cooling system. Minerals cause
deposits and may react adversely with the metals in the engine
and cooling system.
WARNING
Hot exhaust system parts can cause serious burns. Allow adequate time for
the exhaust system to cool. Never perform this procedure with the engine
running.
