PERIODIC MAINTENANCE AND ADJUSTMENT6-166EAU20071CoolantThe coolant level should be checkedbefore each ride. In addition, the cool-ant must be changed at the intervalsspecified in the periodic maintenanceand lubrication chart.EAU54161To check the coolant level1. Place the vehicle on the center-stand.TIP The coolant level must bechecked on a cold engine sincethe level varies with engine tem-perature. Make sure that the vehicle is posi-tioned straight up when checkingthe coolant level. A slight tilt to theside can result in a false reading.2. Remove the left cowling vent pan-el. (See page 3-37.)3. Check the coolant level in thecoolant reservoir.TIPThe coolant should be between theminimum and maximum level marks.4. If the coolant is at or below theminimum level mark, remove thecoolant reservoir cap.5. Add coolant or distilled water toraise the coolant to the maximumlevel mark, and install the coolantreservoir cap. WARNING! Re-move only the coolant reservoircap. Never attempt to removethe radiator cap when the en-gine is hot. [EWA15162] NOTICE: Ifcoolant is not available, use dis-tilled water or soft tap water in-stead. Do not use hard water orsalt water since it is harmful tothe engine. If water has beenused instead of coolant, replaceit with coolant as soon as possi-ble, otherwise the cooling sys-tem will not be protectedagainst frost and corrosion. Ifwater has been added to thecoolant, have a Yamaha dealercheck the antifreeze content ofthe coolant as soon as possible,otherwise the effectiveness ofthe coolant will be reduced.[ECA10473]6.
