2008 ENGINE Cooling System (MZI-3.7) - Mazda CX-9
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 switch is turned 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.
