General Maintenance

Carburetor

The number stamped in the end of the main jet indicates the jet size.  

The jet installed at the time of manufacture is not necessarily correct for 

your elevation.  It's your dealer's responsibility to make sure the correct 

main jet is installed.

Carburetor Adjustments

The frequency at which the carburetors are synchronized or balanced is 

important.  Properly adjusted carburetors can greatly improve engine 

performance, fuel economy, engine life, and reliability.

If you notice any of the following conditions, the carburetor may need 

adjustment:
• Hard starting
• Poor idle
• Overheated pistons and cylinder walls
• Plug fouling
• Poor engine response to various throttle valve openings

CAUTION

Operating the snowmobile with incorrect jetting can result in serious engine 

damage.  Have your Polaris dealer perform all carburetor adjustments to 

ensure all adjustments are done correctly.

Carburetor Water/Sediment Trap

Most Polaris snowmobiles contain patented carburetor bowl water/sedi-

ment traps located at the bottom of each carburetor.  The trap, consisting 

of a hose with a plug, should be drained about every 1000 miles (1600 

km) and inspected for contamination.

Cleaning Procedure
1. Turn the fuel valve off.
2. Place a container or shop 

towels below the plug to 

catch drained fuel.

3. Slide the clamp (1) away 

from the drain plug (2) and 

remove the drain plug from 

the sediment tube.

4. Wipe residue from the plug 

and reinstall it.  Reposition 

and tighten the clamp. 

5. Repeat the draining proce-

dure for any remaining traps.

WARNING

When draining the traps, fuel spillage will occur.  Always work in a well venti-

lated area away from anything that may cause the fuel to ignite, such as open 

flames, sparks, heaters, trouble lights, cigarettes, etc.  Review the fuel warn-

ings on page 73.

General Maintenance

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 124 for Polaris products.

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.

n

Coolant Level

The engine coolant level is controlled by the recovery system.  The 

recovery system components are:
• Coolant bottle or overflow tank
• Engine filler neck
• Pressure cap
• Connecting hoses

Always maintain the coolant level between the minimum and maximum 

marks on the coolant bottle (when engine is cold) to prevent overheating 

and serious engine damage.

CAUTION

Operating the snowmobile with insufficient coolant will result in overheating 

and serious engine damage.  Always maintain the coolant level as recom-

mended.

General Maintenance

Coolant High Temperature Indicator Light

The high temperature indicator light will illuminate when engine cool-

ant temperature becomes too hot for safe continued operation of the 

engine. If you must drive your machine after the high temperature indi-

cator light has come on, drive slowly and stop frequently to allow the 

engine to cool down. Driving in deep snow will also help cool the 

engine.  See your dealer for service. Add coolant if the level is low.

NOTE: Engine performance will be reduced if you continue operating 

when the high temperature light is on.

Flushing the Cooling System

To ensure that the coolant maintains its ability to protect the engine, 

drain the system completely every two years and add a fresh mixture of 

antifreeze and distilled water. This service must be performed when the 

engine is cold.  Ask your Polaris dealer to check the coolant when he 

performs the fall tune-up on your snowmobile.

WARNING

Steam and hot liquids will cause serious burns to your skin.  Never remove 

the pressure cap when the engine is warm or hot.
