2008 Toyota Yaris Fuel Injector Parts Q&A

• Q: How to install the fuel injector on 2008 Toyota Yaris?

  A: Begin with light gasoline or spindle oil application on new O-rings before installing each fuel injector O-ring and proceed to coat fuel delivery pipe contact areas and its respective injector O-ring. The fuel delivery pipe requires installation of the fuel injector during which the O-ring must not be twisted while checking the injector's smooth movement; replace the O-ring if needed. After acquiring 4 new cylinder head injector vibration insulators you can start installing 2 No. 1 delivery pipe spacers. Finish the operation by installing the spacers in correct direction. The first step is to install the fuel delivery pipe sub-assembly with the 4 fuel injectors before establishing the 3 bolts provisionally while being cautious of injector drops and ensuring injector smooth rotation. Tighten the bolts to 19 Nm (194 kgf-cm, 14 ft-lbf) then 9.0 Nm (92 kgf-cm, 80 in-lbf). You must first inspect the fuel tube for scratches or foreign matter before connecting the fuel tube sub-assembly by inserting the tube connector into the delivery pipe until it clicks. Afterward, check the tube security by pulling the tube and then clamp the fuel pipe in place. Apply Toyota Genuine Seal Packing Black or Three Bond 1207B equivalent to the cylinder head while clearing the space of oil then place the cylinder head cover sub-assembly within three minutes before avoiding engine startup for at least two hours. Secure the cover with 9 bolts and 2 nuts and 2 seal washers applied correctly before tightening to 10 Nm (102 kgf-cm, 7.0 ft-lbf) according to sequence. The next step involves installing the wire harness bracket which requires a bolt tightened to 13 Nm (133 kgf-cm, 9.6 ft-lbf). Afterward, connect the connector and wire harness clamp and engine wire harness and fuel injector connectors. The last step consists of connecting ventilation hose Number 2 and the ventilation hose then installing ignition coil Number 1 while connecting the cable to the negative battery terminal at 5.4 Nm (55 kgf-cm, 48 in-lbf) torque and conducting a leak check for fuel and engine oil.
