2009 Toyota Corolla Fuel Injector Parts Q&A

• Q: How to install the fuel injector assembly on 2009 Toyota Corolla?

  A: Start by placing 4 new injector vibration insulators onto the fuel injector assemblies so they can receive a thin petroleum layer spread on their O-ring areas. The installation process requires dropping the assembly onto the fuel delivery pipe sub-assembly by rotating it left and right. At this point the O-ring should not be twisted and all injectors should rotate without resistance. Fitting the 2 No. 1 delivery pipe spacers should begin with their installation on the cylinder head in the proper orientation. The assembly combines the 4 fuel injector assemblies with the fuel delivery pipe sub-assembly before securing it through 2 temporary bolts achieving 21 Nm (214 kgf-cm, 15 ft-lbf) torque then adding a third retaining bolt at the same torque value. Fasten the wire harness bracket with a bolt at 5.0 Nm (51 kgf-cm, 44 in-lbf). Introduce the fuel tube sub-assembly connectors into the delivery pipe until a "click" sound occurs before checking that no scratches or foreign material exists in the connection point through tension tests. You must install a new Type B No. 2 fuel pipe clamp and a new Type A No. 2 fuel pump clamp. The 2 engine wire harness brackets must be secured with bolts that reach 13 Nm (133 kgf-cm, 10 ft-lbf) torque while connecting 4 wire harness clamps, 4 fuel injector assembly connectors, 2 wire harness clamps, and 2 ground wires using 2 bolts. Secure the negative battery terminal connection between the cable and No. 2 ventilation hose with 5.4 Nm (55 kgf-cm, 48 in-lbf) torque. The last step involves fuel leak checking and No. 2 cylinder head cover installation.
