Toyota Sienna Service Manual: Installation

1. INSTALL TIRE PRESSURE WARNING VALVE AND TRANSMITTER

(a) Insert the tire pressure warning valve and transmitter into the valve installation hole. Insert it from the inside of the rim so that the printed surface can be seen.

NOTICE:

• Check that there is no visible deformation, damage, or other abnormalities on the tire pressure warning valve and transmitter.
• Check that there is no foreign matter on the inner grommet and around the rim hole.
• If the tire pressure warning valve and transmitter is installed upside down, it may be damaged or fail to transmit signals when running at high speeds.
• If installing a new tire pressure warning valve and transmitter, write down the ID number before installation.
• It is necessary to register the ID in the ECU after installation (See page TW-20).

(b) Install the washer on the tire pressure warning valve and transmitter from the rim side and tighten the nut.

Torque: 4.0 N*m (41 kgf*cm, 35 in.*lbf)

NOTICE:

• No further tightening is required once the nut is tightened to the specified torque.
• Check that there is no foreign matter on the washer and nut.
• If replacing the tire pressure warning valve and transmitter, make sure that the new grommet, washer, and nut are used.
• Check that there is no oil, water, or lubricant around the rim hole, tire pressure warning valve and transmitter, washer, and nut.

  Failing to do so may result in improper installation.

(c) Set the wheel disc to the mounting machine and install the lower tire bead. Position the main body of the tire pressure warning valve and transmitter in the shaded area shown in the illustration.

NOTICE:

• If the tire pressure warning valve and transmitter is positioned outside this area, it will be interfered with the tire bead, and may cause damage to the tire pressure warning valve and transmitter.
• If the use of lubricant is required when installing the bead, do not apply the lubricant directly to the tire pressure warning valve and transmitter.

(d) Install the upper bead.

NOTICE: Make sure that the tire bead and tool do not interfere with the main body of the tire pressure warning valve and transmitter and that it is not clamped by the bead.

(e) After the tire is inflated, the valve nut may be loose.

Retighten the nut to the specified torque and then check for air leaks with soapy water.

Torque: 4.0 N*m (41 kgf*cm, 35 in.*lbf)

NOTICE: No further tightening is required once the nut is tightened to the specified torque.

2. INSTALL FRONT WHEEL Torque: 103 N*m (1050 kgf*cm, 76 ft.*lbf)

3. INSTALL REAR WHEEL Torque: 103 N*m (1050 kgf*cm, 76 ft.*lbf)
