IGNITION TIMING

Refer to Electrical chapter for ignition timing
procedure.
Ignition Timing:
30°±2° BTDC@5000RPM
ENGINE-TO-FRAME GROUND
Inspect engine-to-frame ground cable connection. Be
sure it is clean and tight.
LIQUID COOLING SYSTEM
OVERVIEW
The engine coolant level is controlled or maintained
by the recovery system.
components are the recovery bottle, radiator filler
neck, radiator pressure cap and connecting hose.
As coolant operating temperature increases, the

tank past the pressure cap and into the radiator.
G Some coolant level drop on new
machines is normal as the system is
purgingitself of trappedair. Observe
coolant levels often during the
break-in period.
G Overheating of engine could occur if
air is not fully purged from system.

COOLANT STRENGTH / TYPE
Test the strength of the coolant using an antifreeze
hydrometer.
Antifreeze Hydrometer
G A 50/50 or 60/40 mixture of Polaris
Premium Coolant (PN 2871323) and
distilled water will provide the
optimum cooling,
protection, and antifreeze protection.
G Do not use tap water. Tap water
contains minerals and impurities
which build up in the system. Do not
add straight antifreeze or straight
water to the system. Straight water
or antifreeze may cause the system
to freeze, corrode, or overheat.

COOLING SYSTEM HOSES

1. Inspect all hoses for cracks, deterioration,
abrasion or leaks. Replace if necessary.
2. Check tightness of all hose clamps.
CAUTION: Do not over-tighten hose clamps at
radiator, or radiator fitting may distort, causing a
restriction to coolant flow.
