ENGINE OIL SOLENOID VALVE REMOVAL/INSTALLATION [SKYACTIV-G 2.0]

WARNING:

• Hot engines and engine oil can cause severe burns. Turn off the engine and wait until it and the engine oil have cooled.

• A vehicle that is lifted but not securely supported on safety stands is dangerous. It can slip or fall, causing death or serious injury. Never work around or under a lifted vehicle if it is not securely supported on safety stands.

• Continuous exposure to USED engine oil has caused skin cancer in laboratory mice. Protect your skin by washing with soap and water immediately after working with engine oil.

1. Disconnect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION.)

2. Remove the front crossmember under cover. (See FRONT CROSSMEMBER UNDER COVER REMOVAL/INSTALLATION.)

3. Remove in the order indicated in the table.

4. Install in the reverse order of removal.

5. Start the engine and confirm that there is no oil leakage.

• If there is oil leakage, repair or replace the applicable part.

4	Engine oil solenoid valve (See Engine Oil Solenoid Valve Removal Note.) (See Engine Oil Solenoid Valve Installation Note.)
5	Gasket

Engine Oil Solenoid Valve Removal Note

1. Cover the area around the engine oil solenoid valve with a cloth because a small amount of engine oil will leak from the engine oil solenoid valve installation area.

CAUTION:

• Do not allow any engine oil to contact the adjacent water pump and water pump body gasket. Otherwise, the gasket could swell causing a seal malfunction.

Engine Oil Solenoid Valve Installation Note

1. Remove sealant around the cylinder block screw holes before installing the engine oil solenoid valve.

2. After tightening the three bolts shown in the figure, tighten the first tightened bolt to the specified tightening torque again.

NOTE:

• The tightening order for the three bolts is optional.

Tightening torque

• 12—16 N·m {123—163 kgf·cm, 107—141 in·lbf}

Oil Pressure Switch Installation Note

CAUTION:

• Verify that there is no sealant between 1.7—2.7 mm {0.07—0.10 in} from the end of the oil pressure switch to prevent a possible operation malfunction.

1. When reusing the oil pressure switch, apply silicone sealant (TB2403 or equivalent) to the threads of the oil pressure switch.

CAUTION:

• Install the oil pressure switch before the applied sealant starts to harden.

2. Install the oil pressure switch.

Tightening torque

• 12—17 N·m {123—173 kgf·cm, 107—150 in·lbf}
