Periodic maintenance and adjustment When the engine has cooled, place a thick rag or towel over the coolant reservoir cap, and slowly rotate the cap counterclockwise to the detent. This procedure allows any residual pressure to escape. When the hissing sound has stopped, press down on the cap while turning counterclockwise and remove it. To check the coolant level 1. Place the snowmobile on a level surface and apply the parking brake. 2. Remove the top cover (PZ50RT / PZ50GT / PZ50MT) or open the shroud (PZ50VT), and then remove the right upper cover. (See page 48 for removal procedures.) 3. Check the coolant level in the coolant reservoir 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] 1. "COLD LEVEL" mark 4. Install the right upper cover, and then install the top cover (PZ50RT / PZ50GT / PZ50MT) or close the shroud (PZ50VT). Bleeding the cooling system The cooling system must be bled if the coolant reservoir becomes empty, if air can be seen in the cooling system, or if there is a cooling system leak. Consult a Yamaha dealer. ECS00500 NOTICE Operating the engine with an improperly bled cooling system can cause overheating and severe engine damage. Replenishing the coolant 1. 2. Place the snowmobile on a level surface and apply the parking brake. Remove the top cover (PZ50RT / PZ50GT / PZ50MT) or open the shroud (PZ50VT), and then remove the right upper cover. (See page 48 for removal procedures.) Remove the coolant reservoir cap, add the recommended coolant until it reaches the "COLD LEVEL" mark, and then install the cap. 3. 60
