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).

Z-type Engines

•

In the Z-type engine line-up the following engines are available:

–

ZJ engine with 1.3 L displacement (also termed as 1.3 MZR engine)

–

Z6 engine with 1.6 L displacement (also termed as 1.6 MZR engine)

•

Both engines are fitted in the Mazda3 models. They are equipped with a multipoint
manifold injection system and a distributorless ignition system (direct ignition coils).
