Maintenance and Care Owner Maintenance Inspect the antifreeze protection and coolant level in the coolant reservoir at least once a year-at the beginning of the winter season-and before traveling where temperatures may drop below freezing. Inspect the condition and connections of all cooling system and heater hoses. Replace any that are swollen or deteriorated. The coolant should be at full in the radiator and between the F and L marks on the coolant reservoir when the engine is cool. M Changing Coolant (Without Rear Heater) Change coolant according to Scheduled Maintenance (page 8-3). CAUTION • Use only soft (demineralized) water in the coolant mixture. Water that contains minerals will cut down on the coolant's effectiveness. • Don't add only water. Always add a proper coolant mixture. • The engine has aluminum parts and must be protected by an ethyleneglycol-based coolant to prevent corrosion and freezing. • DO NOT USE alcohol or methanol antifreeze. DO NOT MIX alcohol or methanol with the coolant. This could damage the cooling system. • Don't use a solution that contains more than 60 % antifreeze. This would reduce effectiveness. If it's at or near L, add enough coolant to the coolant reservoir to provide freezing and corrosion protection and to bring the level to F. For mixture percentage: Protection Above -16°C (3°F) Above -26°C (-15°F) Above -40°C (-40°F) Volume Antifreeze Water solution 35% 65% 45% 55% 55% 45% CAUTION Radiator coolant will damage paint. Rinse it off quickly. Do not overfill. If new coolant is required frequently, consult an Authorized Mazda Dealer. 8-13
