Mazda CX-30 2020 Owner's Manual page 479

NOTE
If the replacement is not done using
the correct procedure indicated in the
service manual, it could cause an
engine malfunction. Consult an expert
repairer (we recommend an
Authorised Mazda Repairer) for
details.
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
travelling 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 FULL and
LOW marks on the coolant reservoir
when the engine is cool.
If it is at or near LOW, add enough
coolant to the coolant reservoir to
provide freezing and corrosion
protection and to bring the level to
FULL.
Securely tighten the coolant reservoir
tank cap after adding coolant.
Owner Maintenance
CAUTION
Radiator coolant will damage paint.
Rinse it off quickly if spilled.
If the "FL22" mark is shown on or
near the cooling system cap, use of
FL-22 is recommended when
replacing engine coolant. Using
engine coolant other than FL-22 may
cause serious damage to the engine
and cooling system.
If the coolant reservoir is empty or new
coolant is required frequently, consult
an expert repairer (we recommend an
Authorised Mazda Repairer).
