2. Run the engine at idle for 1 min.
3. Repeat steps (1), (2) approx. 2 times.
4. Operate the heater at the maximum temperature and airflow, and verify that hot air blows from
vent.
11. Stop the engine, and inspect the engine coolant level after the engine coolant temperature decreases. If it
is low, repeat steps 7-10.
12. Inspect for engine coolant leakage. (See ENGINE COOLANT LEAKAGE INSPECTION [MZI-3.5].)
ENGINE COOLANT LEAKAGE INSPECTION [MZI-3.5]
WARNING:
1. Inspect the engine coolant level. (See ENGINE COOLANT LEVEL INSPECTION [MZI-3.5].)
2. Remove the cooling system cap.
3. Install the SST and a radiator cap tester to the coolant reserve tank filler port.
4. Apply pressure using the radiator cap tester.
CAUTION:
Engine coolant leakage inspection pressure 122.6 kPa {1.25 kgf/cm
5. When pressurizing the cooling system, verify that the pressure is maintained.

2007 ENGINE Cooling System (MZI-3.5) - 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.
Applying more than 122.6 kPa {1.25 kgf/cm
damage the hoses, fittings, and other components, and cause
leakage.
