Engine Coolant

• For all current Mazda vehicles except for Mazda2 (DY) Mazda has developed a special

engine coolant called ‘FL22’. This coolant has a significantly longer replacement interval

than conventional coolant. Whereas conventional coolant must replaced at first every

100,000 km or 4 years (whichever occurs first) and after that every 2 years, FL22 coolant

must be replaced every 200,000 km or 11 years (whichever occurs first). The only

exception are models with L3-T engine (Mazda3 MPS, Mazda6 MPS and Mazda CX-7),

which have a coolant replacement interval of 195,000 km or 11 years (whichever occurs

first).

• FL22 coolant and conventional coolant are both ethylene glycol-based and can be

mixed. They are both green, making them impossible to distinguish visually. For this

reason, vehicles designated for use with FL22 coolant have a corresponding label on the

radiator cap itself or on the surrounding area.

• If the engine coolant on a vehicle designated for use with conventional coolant is

replaced by FL22 coolant, the replacement interval changes to 100,000 km or 5 years

(whichever occurs first). In order to indicate the new replacement interval, a sticker has

to be applied next to the coolant reserve tank (refer to the respective service information

for details).

NOTE: When replacing the coolant, the cooling system has to be flushed (refer to the

workshop manual for details).
