Fuel Injector Replacement SOHC

Caution: Do not allow smoking or the use of open flames in the area where work on the fuel or EVAP system is taking place. Anytime work is being done on the fuel system, disconnect the negative battery cable, except for those tests where battery voltage is required.

Important: Use care in removing fuel injectors to prevent damage to electrical connector pins on the fuel injector and the nozzle. The fuel injector is serviced as a complete assembly only. Since it is an electrical component, it should not be immersed in any type of cleaner. Support the fuel rail to avoid damaging other components while removing the fuel injector.

1. Remove the fuel rail.



2. Slide the fuel injector retainer clip off the fuel injector.

Important: Clean the fuel rail prior to removing the fuel injector.

3. Remove the port fuel injector assembly and plug the fuel injector port with a clean shop towel.

Important: Any time the fuel system is opened for service, O-ring seals used with related components must be replaced.

4. Remove the fuel injector O-rings and discard.

Important: DOHC (LL0) and SOHC (L24) fuel injectors are not interchangeable. Verify that the correct fuel injectors are installed in the fuel rail. The fuel injectors are identified by color coded plastic rings located near the bottom of the fuel injectors. The 2000 model year SOHC injector is identified by a blue ring.

1. Lubricate the new fuel injector O-ring seals with clean engine oil and install on the fuel injector assembly.




Important: DOHC (LL0) and SOHC (L24) fuel injectors are not interchangeable. Verify that the correct fuel injectors are installed in the fuel rail. The fuel injectors are identified by color coded plastic rings located near the bottom of the fuel injectors. The 2001-02 model year SOHC injector is identified by an off-white rung.

2. Lubricate the new fuel injector O-ring seals with clean engine oil and install on the fuel injector assembly.



3. Install the clip onto the injector prior to installing the injector to the fuel rail.
4. Install the port fuel injector assembly into the fuel rail, with the fuel injector's electrical connector facing upward.
5. Install the fuel rail assembly.
