Engine Cooling System

NOTE: This procedure is only required if the cooling sys-

tem has been drained for maintenance and/or repair.

However, if the recovery bottle has run dry, or if overheat-

ing is evident, the level in the radiator should be inspected

and coolant added if necessary.

WARNING Never remove the pressure cap when

the engine is warm or hot. Escaping steam can cause se-

vere burns. The engine must be cool before removing the

pressure cap.

NOTE: Use of a non-standard pressure cap will not allow

the recovery system to function properly.

To access the radiator pressure cap:

Gen II - To access the pressure cap, remove the access

cover on the front of the ATV just below the oil cap. Using

a flat, stubby screwdriver loosen the screw 1/4 turn and

pull the cover forward and up to remove.

Gen III - To access the pressure cap, clean the area

around the oil cap and remove the oil cap (2-cycle mod-

els). Remove front cover by placing your fingers under the

front of the cover and pulling upward. Reinstall oil cap.

Gen IV - Remove the four screws securing front rack. Re-

move front cover by placing your fingers under the front of

the cover and pulling upward.
