Camshaft Oil Control Valve (For Sedan) Installation

Apply a light coat of engine oil to a new O-ring and install it onto the camshaft timing oil control valve assembly.

NOTICE:

Do not twist the O-ring.

Install the camshaft timing oil control valve assembly with the bolt.

Torque:

7.5 N*m{76 kgf*cm, 66 in.*lbf}

Connect the camshaft timing oil control valve assembly connector.

Provisionally install the fan belt adjusting bar with the bolt and nut.

Tighten the nut to the specified torque.

Torque:

11 N*m{112 kgf*cm, 8.1 ft.*lbf}

Provisionally install the fan and generator V belt onto each pulley.

NOTICE:

1. Make sure that there is no foreign matter or liquid, such as oil, on the belt and pulleys.
   
2. Make sure that the V belt is securely fitted into the rib grooves of the pulley.
   

Insert an adjusting bar between the engine mounting bracket and generator assembly. Pull the adjusting bar toward the vehicle front to adjust the generator V belt tension (YARIS_NCP93 RM000001DCH00ZX_01_0001.html).

NOTICE:

Do not insert the adjusting bar between the camshaft timing oil control valve assembly and generator assembly. It could damage the camshaft timing oil control valve assembly.

First tighten bolt A, then tighten bolt B.

Torque:

19 N*m{189 kgf*cm, 14 ft.*lbf} for bolt A

54 N*m{551 kgf*cm, 40 ft.*lbf} for bolt B

Check the belt for wear, cracks or other signs of damage.
If any of the following defects is found, replace the V-ribbed belt.

HINT:

1. The belt is cracked.
   
2. The belt is worn out to the extent that the wires are exposed.
   
3. The belt has chunks missing from the ribbed groves.
   

Check that the belt fits properly in the ribbed grooves.

HINT:

Check with your hand, to confirm that the belt has not slipped out of the grooves on the bottom to the pulley. If it has slipped out, replace the V-ribbed belt. Install a new V-ribbed belt correctly.

Inspect the V belt deflection and tension.

Deflection:

Item	Specified Condition
New belt	8.0 to 9.0 mm (0.31 to 0.35 in)
Used belt	12.5 to 13.5 mm (0.49 to 0.53 in)

Tension:

Item	Specified Condition
New belt	700 to 800 N (71 to 82 kg, 157 to 180 lb)
Used belt	300 to 400 N (31 to 41 kg, 67 to 90 lb)

HINT:

1. When inspecting the V belt deflection, apply 98 N (10 kgf) tensile force to it.
   
2. Perform the V belt inspection and adjustment while the engine is cold.
   
3. V-ribbed belt tension and deflection should be checked immediately after installation of a new belt, and after cranking the engine when inspecting a used belt.
   
4. Check the V belt deflection at the point between the specified pulleys where the deflection is greatest.
   
5. When installing a new belt, set its tension to the intermediate value of the specification.
   
6. When inspecting a belt which has been used for over 5 minutes, apply the Used Belt specifications.
   
7. When reinstalling a belt which has been used for over 5 minutes, adjust its deflection and tension to the intermediate values of each Used Belt specification.
   
8. V-ribbed belt tension and deflection should be checked after 2 revolutions of engine cranking.
   
9. When using a belt tension gauge, confirm its accuracy by using a master gauge first.
   

Tighten the 2 A nuts, then the 2 B nuts.

Torque:
