Place the snowmobile on a level surface and apply the parking brake. Remove the top cover and the right side cover. (See page 63 for removal procedures.) Check the coolant level in the coolant recovery tank when the engine is cold. If the coolant level is below the "COLD LEVEL" mark, add coolant until it reaches the "COLD LEVEL" mark. (See the following section "Replenishing the coolant" for more details.) NOTICE: If coolant is not available, use distilled water or soft tap water instead. Do not use hard water or salt water since it is harmful to the engine. If water has been used instead of coolant, replace it with coolant as soon as possible, otherwise the cooling system will not be protected against frost and corrosion. If water has been added to the coolant, have a Yamaha dealer check the antifreeze content of the coolant as soon as possible, otherwise the effectiveness of the coolant will be reduced. [ECS00492] 4.
