Fuel Injector Assembly (SOHC): Installation

NOTE: DOHC (LLO) 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, and the 2001-02 model year SOHC injector is identified by an off-white ring.
