id0112u0800700

Replacement Part

O-ring
Quantity: 1
Location of use: Water inlet pipe
Gasket
Quantity: 1
Location of use: Water pump component

Oil and Chemical Type

Engine coolant
Type: Recommended engine coolant
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.
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.Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION [(US)].)

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

3.Remove the front splash shield (RH). (See SPLASH SHIELD REMOVAL/INSTALLATION.)

4.Drain the engine coolant. (See ENGINE COOLANT REPLACEMENT [SKYACTIV-G (WITH CYLINDER DEACTIVATION (US))].)

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 (WITHOUT CYLINDER DEACTIVATION (US))].)

6.Remove the engine coolant temperature (ECT) sensor No.1. (See ENGINE COOLANT TEMPERATURE (ECT) SENSOR REMOVAL/INSTALLATION [SKYACTIV-G (WITHOUT CYLINDER DEACTIVATION (US))].)

7.Remove in the order indicated in the table.

8.Install in the reverse order of removal.

9.Refill the engine coolant. (See ENGINE COOLANT REPLACEMENT [SKYACTIV-G (WITH CYLINDER DEACTIVATION (US))].)

10.Inspect for engine coolant leakage. (See ENGINE COOLANT LEAKAGE INSPECTION [SKYACTIV-G (WITHOUT CYLINDER DEACTIVATION (US))].)

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 water pump pulley.

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



Water Pump Component Removal Note

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

2.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 {2 US qt, 2 Imp qt} or less of engine coolant flowing in the engine will drain out.

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



O-ring Installation Note

Caution
• Do not apply oil (such as engine oil, ATF) 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

Caution
• Assemble the water pump gasket to the correct direction shown in the figure. Otherwise, it could leak engine coolant and damage the engine.

• Do not apply oil (such as engine oil, ATF) to the water pump gasket. Otherwise, the gasket could swell causing a seal malfunction.

1.Insert a new water pump gasket into the water pump groove.

2.Install the water pump.

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

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 bolts.

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.
