coolant system MAZDA MODEL MX-5 MIATA 2006 User Guide

Black plate (287,1)
CAUTION
Radiator coolant will damage paint.
Rinse it off quickly if spilled.
If the coolant reservoir is empty or new
coolant is required frequently, consult an
Authorized Mazda Dealer.
q Changing Coolant
Change coolant according to Scheduled
Maintenance (page 8-3).
CAUTION
lUse only soft (demineralized) water
in the coolant mixture. Water that
contains minerals will cut down on
the coolant's effectiveness.
lDon't add only water. Always add a
proper coolant mixture.
lThe engine has aluminum parts and
must be protected by an ethylene-
glycol-based coolant to prevent
corrosion and freezing.
lDO NOT USE coolants Containing
Alcohol, methanol, Borate or
Silicate.
These coolants could damage the
cooling system.
lDO NOT MIX alcohol or methanol
with the coolant. This could damage
the cooling system.
lDon't use a solution that contains
more than 60% antifreeze.
This would reduce effectiveness.
NOTE
If the “FL22 ”mark is shown on or near
the cooling system cap, use FL22 type
engine coolant. If engine coolant other
than FL22 type is used, the engine
coolant must be replaced earlier than
the specified replacement interval
indicated in the scheduled maintenance
(page 8-3).
Except FL22 type

To change coolant
WARNING
Removing the Cooling System Cap:
Removing the cooling system cap
while the engine is running or hot is
dangerous. This might lead to cooling
system and engine damage and could
result in serious injury from escaping
hot coolant or steam. Turn off the
engine and wait until it's cool. Even
then, be very careful when removing
the cap. Wrap a thick cloth around the
cap and slowly turn it
counterclockwise to the first stop.
Step back while the pressure escapes.
When you're sure all the pressure is
gone, press down on the cap―still
using a cloth ―turn the cap, and
remove it.
1. Make sure the engine is not running and it has cooled.
2. Remove the cooling system cap.
Tighten Tighten
Loosen Loosen
3. Remove the radiator drain plug and
drain the coolant into a suitable
container. Properly dispose of the used
coolant. 4. Flush out the system with running
water.
5. Drain the system completely. Insert and tighten the plug. Add as much
ethylene-glycol-based coolant mixture
and water (or undiluted FL22) as
necessary to provide freezing and
corrosion protection.
6. In extremely cold climates, add the mixture percentage recommended in
the coolant mixture percentage table.
7. Run the engine at idle with the cooling system cap off. Slowly add additional
coolant if necessary.
8. At this point, wait until the engine reaches normal operating temperature;
then depress the accelerator two or
three times. Add more coolant, if
necessary, until the system is full.
9. Install the cooling system cap. Inspect all connections for leaks. Inspect the
level in the coolant reservoir one more
time and verify that the coolant level is
between the F and L marks.
