To enhance service life, reduce waste material, and lower maintenance costs, long-life pre-mixed "FL22" engine
coolant has been introduced into mass-production for the applicable models listed in this service bulletin.
Models with FL22 long-life coolant can be identified by the "FL22" marking on the cooling system cap label. It is
recommended that FL22 coolant continue to be used for models originally filled with FL22 coolant from the factory.
CAUTION: FL22 coolant is "pre-mixed" and must be added to the cooling system as is. DO NOT ADD
WATER TO FL22 COOLANT. Adding water will dilute the solution and lessen the effectiveness of
the coolant.
When coolant replacement becomes necessary for older Mazda models not originally filled with FL22 coolant,
FL22 coolant can be used. If FL22 coolant is used for older models, be sure to place a FL22 sticker on the
reserve tank or degas bottle to indicate FL22 coolant is being used. Six (6) FL22 stickers are included with each
case of coolant. Additional FL22 stickers can be order through MStore (p/n 9999-95-FL22).
NOTE:In the case of older models, the coolant replacement interval is every five (5) years or 60,000 miles
(96,000 km).FL22 coolant is compatible with current (Green) ethylene glycol coolant.If FL22 coolant is mixed with existing Orange coolant, coolant color will turn black. For customer
satisfaction, DO NOT mix FL22 coolant and Orange coolant.
