SPARK PLUG CONDITION
NORMAL PLUG
The normal insulator tip is gray, tan or light brown. There will be few combustion
deposits. The electrodes are not burned or eroded. This indicates the proper
type and heat range for the engine and the service.
WET FOULED PLUG
The wet fouled insulator tip is black. A damp oil film covers the firing end. There
may be a carbon layer over the entire nose. Generally, the electrodes are not
worn. General causes of fouling are excessive oil or use of non-recommended
injection oil.
COOLING SYSTEM
COOLANT
POLARIS recommends the use of POLARIS Antifreeze 50/50 Premix. This
antifreeze is already premixed and ready to use. Do not dilute with water.
To ensure that the coolant maintains its ability to protect the engine, we
recommend that the system be completely drained every five (5) years and fresh
Antifreeze 50/50 Premix.
Any time the cooling system has been drained for maintenance or repair,
replace the coolant with fresh Antifreeze 50/50 Premix.
COOLANT LEVEL
The engine coolant level is controlled by the recovery system. The recovery
system components are:
• Coolant bottle/overflow tank
• Pressure cap
• Connecting hoses
Always maintain the coolant level at or slightly above the FULL COLD mark on
the coolant bottle (when the engine is cold).
1. Stop the engine.
2. Open the right side panel.
3. View the coolant level in the coolant bottle. Add coolant as needed.
NOTICE
Operating the snowmobile with insufficient coolant will result in overheating
and serious engine damage. Always maintain the coolant level as
recommended.
