5. Fill the coolant reservoir slowly with the proper coolant mixture (see

above), to within the “COLD FILL RANGE” or the “FULL COLD”
level on the reservoir. If you removed the radiator cap in an overflow
system, fill the radiator until the coolant is visible and radiator is
almost full.

6. Replace the cap. Turn until tightly installed. (Cap must be tightly

installed to prevent coolant loss.)

After any coolant has been added, check the coolant concentration, refer
to Checking engine coolant. If the concentration is not 50/50
(protection to –34° F/–36° C), drain some coolant and adjust the
concentration. It may take several drains and additions to obtain a 50/50
coolant concentration.

Whenever coolant has been added, the coolant level in the coolant
reservoir should be checked the next few times you drive the vehicle. If
necessary, add enough 50/50 concentration of engine coolant and
distilled water to bring the liquid level to the proper level.

If you have to add more than 1.0 quart (1.0 liter) of engine coolant per
month, have your authorized dealer check the engine cooling system.
Your cooling system may have a leak. Operating an engine with a low
level of coolant can result in engine overheating and possible engine
damage.

Recycled engine coolant

Not all coolant recycling processes produce coolant which meets Mazda
specification. Use of a recycled engine coolant which does not meet
Mazda specifications may harm engine and cooling system components.

Always dispose of used automotive fluids in a responsible manner.

Follow your community’s regulations and standards for recycling and
disposing of automotive fluids.

Coolant refill capacity

To find out how much fluid your vehicle’s cooling system can hold, refer
to Maintenance product specifications and capacities in this chapter.

Fill your engine coolant reservoir as outlined in Adding engine coolant
in this section.

Severe climates

If you drive in extremely cold climates (less than –34° F [–36° C ]):
It may be necessary to increase the coolant concentration

above 50%.
