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.
1. Clean the cooling system cap and the sealed part.
2. Inspect the cooling system cap for cracks or everted seal.
If there is any malfunction, replace the cooling system cap.
3. Attach the cooling system cap to the radiator cap tester.

4. Hold the cooling system cap downward and apply pressure gradually. Verify that the pressure is held stable for 10 s.
If the pressure is not held stable, replace the cooling system cap.

Intake Air Temperature (Iat) Sensor Inspection
IAT Sensor No.1
Resistance inspection
NOTE:
Because the IAT sensor No.1 is integrated in the MAF sensor, replacing the
IAT sensor No.1 includes replacement of the MAF sensor/IAT sensor No.1.
1. Disconnect the negative battery cable..
2. Disconnect the MAF sensor/IAT sensor No.1 ...
