Mazda CX-5 Owners Manual: Engine Coolant
Inspecting Coolant Level
WARNING
Do not use a match or live flame in the engine compartment. DO NOT ADD COOLANT WHEN THE ENGINE IS HOT:
A hot engine is dangerous. If the engine has been running, parts of the engine compartment can become very hot. You could be burned.
Carefully inspect the engine coolant in the coolant reservoir, but do not open it.
Switch the ignition to off and make sure the fan is not running before attempting to work near the cooling fan:
Working near the cooling fan when it is running is dangerous. The fan could continue running indefinitely even if the engine has stopped and the engine compartment temperature is high. You could be hit by the fan and seriously injured.
Do not remove either cooling system cap when the engine and radiator are hot:
When the engine and radiator are hot, scalding coolant and steam may shoot out under pressure and cause serious injury.
NOTE
Changing the coolant should be done by an Authorized Mazda Dealer.
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 traveling 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 F and L marks on the coolant reservoir when the engine is cool.
If it is at or near L, add enough coolant to the coolant reservoir to provide freezing and corrosion protection and to bring the level to F.
Securely tighten the coolant reservoir tank cap after adding coolant.
CAUTION
●Radiator coolant will damage paint.
Rinse it off quickly if spilled.
● Use only soft (demineralized) water in the coolant mixture.
Water that contains minerals will cut down on the coolant's effectiveness.
● Do not add only water. Always add a proper coolant mixture.
● The engine has aluminum parts and must be protected by an ethylene-glycol-based coolant to prevent corrosion and freezing.
● DO NOT USE coolants Containing Alcohol, methanol, Borate or Silicate.
These coolants could damage the cooling system.
● DO NOT MIX alcohol or methanol with the coolant. This could damage the cooling system.
● Do not 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, it is recommended to use Mazda Genuine FL22 engine coolant .
If the coolant reservoir is empty or new coolant is required frequently, consult an Authorized Mazda Dealer.
Engine Oil
NOTE
Changing the engine oil should be performed by an Authorized Mazda Dealer.

Inspecting Brake/Clutch Fluid Level
The brakes and clutch draw fluid from the same reservoir.
Inspect the fluid level in the reservoir regularly. It should be kept at MAX.

Refrigerant Pressure Sensor [Manual Air Conditioner]
Purpose
The refrigerant pressure sensor detects the refrigerant pressure in the refrigerant
cycle.
Function
The refrigerant pressure sensor converts the detected refrigerant pressure
to an electric signal and sends it to the PCM.
Construction
The refriger ...
Liftgate Light Removal/Installation
NOTE:
Fogging or condensation on the inside of the liftgate light may occur, however,
it is a natural phenomenon occurring as a result of a temperature difference
between the interior and exterior of the liftgate lights and has no effect on
the light performance. Fogging or condensa ...
Engine Coolant Replacement
WARNING:
Never remove the cooling system cap or loosen the radiator drain plug while
the engine is running, or when the engine and radiator are hot. Scalding engine
coolant and steam may shoot out and cause serious injury. It may also damage
the engine and cooling system.
