WATER PUMP REMOVAL/INSTALLATION [SKYACTIV-G 2.0]

id0112h4800700

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 2.5 turns. Step back while the pressure escapes.

•  When you are sure all the pressure is gone, turn the cap using the cloth, and remove it.

Note

•  Do not disassemble the water pump because it is a precision unit.

•  Remove/install the water pump pulley and water pump from the underside of the vehicle.

1.  Remove the battery cover. (See BATTERY REMOVAL/INSTALLATION [SKYACTIV-G 2.0].)

2.  Disconnect the negative battery cable. (See BATTERY REMOVAL/INSTALLATION [SKYACTIV-G 2.0].)

3.  Remove the aerodynamic under cover No.2 and splash shield as a single unit. (See AERODYNAMIC UNDER COVER NO.2 REMOVAL/INSTALLATION.)(See SPLASH SHIELD REMOVAL/INSTALLATION.)

4.  Drain the engine coolant. (See ENGINE COOLANT REPLACEMENT [SKYACTIV-G 2.0].)

5.  Remove the water pump drive belt with the generator drive belt still installed and set it out of the way. (See DRIVE BELT REMOVAL/INSTALLATION [SKYACTIV-G 2.0].)

6.  Remove in the order indicated in the table.

7.  Install in the reverse order of removal.

8.  Refill the engine coolant. (See ENGINE COOLANT REPLACEMENT [SKYACTIV-G 2.0].)

9.  Inspect for engine coolant leakage. (See ENGINE COOLANT LEAKAGE INSPECTION [SKYACTIV-G 2.0].)

Water Pump Pulley Removal Note

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 (stretch belt), damage to the pulley, and rust.

1.  Align the water pump pulley hole with the water pump hole as shown in the figure.

2.  Insert an appropriate bolt (length 70 mm {2.8 in}) into the water pump hole shown in the figure and lock the water pump pulley against rotation.

3.  Remove the bolt used for locking the water pump pulley against rotation.

Water Pump Component Removal Note

1.  Remove the water inlet pipe stay bolt.

2.  Place a container under the engine to collect the engine coolant remaining in the engine.

3.  Slightly loosen the three water pump component bolts shown in the figure and collect the draining engine coolant into a container.

Caution

•  Do not remove the water pump component completely at this time because the remaining approx. 2 L or less of engine coolant flowing in the engine will drain out.

4.  After the engine coolant stops draining, remove the water pump component.

O-ring Installation Note

Caution

•  Do not apply oil (engine oil, ATF etc.) to the O-ring of the water inlet pipe. Otherwise, the O-ring could swell causing a seal malfunction.

1.  Apply engine coolant to a new O-ring.

2.  Install the O-ring to the water inlet pipe.

Water Pump Component Installation Note

1.  Tighten the bolts in the order shown in the figure.

2.  Clean away the sealant adhering to the bolt hole on the cylinder block side of the water inlet pipe stay.

3.  Install a new water inlet pipe stay bolt.

Water Pump Pulley Installation Note

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 (stretch belt), damage to the pulley, and rust.

1.  Install the water pump pulley to the water pump and temporarily tighten the bolt

2.  Align the water pump pulley hole with the water pump hole as shown in the figure.

4.  Completely tighten the water pump pulley bolt to the specified torque.

5.  Remove the bolt used for locking the water pump pulley against rotation.
