ENGINE COOLANT LEAKAGE INSPECTION [SKYACTIV-D 1.5]

id0112q2800500

Warning
•  If the engine cooling system cap or the water-cooled charge air cooler reserve tank cap is removed when the engine is hot, steam and boiling water may be injected, causing severe burns or severe injury. Perform the removal of the engine cooling system cap and water-cooled charge air cooler reserve tank cap when the engine is cool.
•  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.  Inspect the engine coolant level. (See ENGINE COOLANT LEVEL INSPECTION [SKYACTIV-D 1.5].)

2.  Remove the engine cooling system cap.

3.  Install the radiator cap tester to the engine radiator filler neck.

4.  Apply pressure using the radiator cap tester.

Caution
•  Applying more than 122.6 kPa {1.250 kgf/cm2, 17.78 psi} can damage the hoses, fittings, and other components, and cause leakage.

5.  When pressurizing the cooling system, verify that the pressure is maintained.

•  If the gauge needle drops, it may indicate water leakage. Repair or replace the applicable part.
