Mazda CX-5 Service & Repair Manual: Cooling System Service Warnings
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.
-
Turn off the engine and wait until it is cool. Even then, be very careful when removing the cap. Wrap a thick cloth around it and slowly turn it counterclockwise to the first stop. Step back while the pressure escapes.
-
When you are sure all the pressure is gone, press down on the cap using the cloth, turn it, and remove it.
-
Depending on the vehicle, the cooling fan may operate suddenly even when the ignition is off. Therefore, keep hands and tools away from the cooling fan even if the cooling fan is not operating to prevent injury to personnel or damage to the cooling fan. Always disconnect the negative battery cable when servicing the cooling fan or parts near the cooling fan.
Cooling System Cap

The cylinder head gasket is installed between the cylinder head and cylinder
block to prevent leakage of air-fuel mixture, combustion gas, engine oil, and
engine coolant.
Construction
A four-layer type metal gasket has been adopted for the cylinder head ga ...
Awd Control Module
Purpose, Function
The AWD CM calculates the optimal amount of torque distribution for the rear
wheels and outputs a corresponding electric current to the electronic control
coupling (AWD solenoid). This calculation is based on the accelerator pedal
angle, four-wheel speed, engine spe ...
Oil Shower Pipe
Outline
Mechanical resistance loss has been reduced through structural changes to
achieve optimum fuel economy. An oil shower pipe has been adopted as a part
of this structural change.
Purpose, Function
The oil shower pipe injects engine oil to lubricate the contact points ...
