Oil and chemical type

Warning

•  If the 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 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.

Caution

•  Be careful not to damage the belt groove and surface of the water pump pulley when using tools, otherwise it will cause wear, breakage, abnormal noise of the drive belt, damage to the pulley, and rust.

•  If coolant leakage from the water pump is considered, refer to [Determination Criteria for Water Pump Coolant Leakage] to determine. (See Determination Criteria for Water Pump Coolant Leakage.)

1.  Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION [(E)].)

2.  Remove front under cover No.2. (See FRONT UNDER COVER No.2 REMOVAL/INSTALLATION.)

Determination Criteria for Water Pump Coolant Leakage

•  If any coolant residue (green) around the steam hole can be verified but there is no large solid matter adhered to it as shown in the following figure, the residue is caused by a small amount of steam blowing through the steam hole, not coolant leakage. Therefore, this does not indicate a problem.

•  If a large amount of solid matter is adhered to the area around the steam hole or the area is wet by coolant as shown in the following figure, a water pump seal or gasket malfunction can be considered. Therefore, perform the coolant leakage inspection and replace the water pump or gasket. (See ENGINE COOLANT LEAKAGE INSPECTION [SKYACTIV-X 2.0].)
