Periodic maintenance and adjustment7-147EAUS1203CoolantThe coolant level should be checkedregularly. In addition, the coolant mustbe changed at the intervals specified inthe periodic maintenance chart.TIPIf genuine Yamaha coolant is not avail-able, use an ethylene glycol antifreezecontaining corrosion inhibitors for alu-minum engines and mix with distilledwater at a 1:1 ratio.EAU20097To check the coolant levelSince the coolant level varies with en-gine temperature, check when the en-gine is cold.1. Park the vehicle on a level surface.2. With the vehicle in an upright posi-tion, look at the coolant level in thereservoir.3. If the coolant is at or below the mi-nimum level mark, remove thecoolant reservoir cap. WARNING!Remove only the coolant reser-voir cap. Never attempt to re-move the radiator cap when theengine is hot. [EWA15162]4. Add coolant to the maximum levelmark. NOTICE: If coolant is notavailable, use distilled water orsoft tap water instead. Do notuse hard water or salt watersince it is harmful to the engine.If water has been used insteadof coolant, replace it with cool-ant as soon as possible, other-wise the cooling system will notbe protected against frost andcorrosion. If water has beenadded to the coolant, have aYamaha dealer check the anti-freeze content of the coolant assoon as possible, otherwise theeffectiveness of the coolant willbe reduced.
