Removal
- Release fuel pressure. See «FUEL PRESSURE RELEASE»(ref-123341-S24445119442001092100000). Drain cooling system. Disconnect negative battery cable. On Millenia, remove air intake duct, MAF sensor and air cleaner assembly. Remove water hose and throttle body assembly. Disconnect necessary control cables, electrical connections, coolant hoses, vacuum hoses and fuel lines. Remove pipe, harness, and EGR valve and pipe.
- On 626, remove fresh-air duct, air cleaner assembly, MAF sensor and air hose. Disconnect necessary control cables, electrical connections, coolant hoses, vacuum hoses and fuel lines. Remove throttle body and IAC valve. Remove fuel distributor and intake manifold.
- On all models, loosen intake manifold retaining bolts and nuts evenly using several steps. Remove intake manifold assembly and gaskets. (Scheme 6)or (Scheme 7).
- If removing fuel injectors, remove retaining bolts, fuel injector retainer, insulators, fuel injectors, fuel rail and pressure regulator. Remove fuel rail insulators (if necessary). (Scheme 6) Fuel rail insulators are located between fuel rail and intake manifold.
| CAUTION | Ensure notch on side of fuel injector engages with notch in fuel rail. |
- To install fuel injectors, install NEW "O" rings onto fuel injector. Coat "O" rings with engine oil. Using twisting motion, install fuel injector into fuel rail so notch on side of fuel injector engages notch in fuel rail.
- Install NEW insulators and "O" rings into fuel rail. Install and tighten retaining bolts to specification. See «TORQUE SPECIFICATIONS»(ref-123341-S20277020582001092100000) . To install remaining components, reverse removal procedure. Install all intake manifold retaining bolts and nuts before tightening to specification. Tighten all fasteners evenly to specification. See «TORQUE SPECIFICATIONS»(ref-123341-S20277020582001092100000) .
- Fill and bleed cooling system. See «COOLING SYSTEM BLEEDING»(ref-123341-S11800930722001092100000) . Ensure accelerator cable has .04-.11" (1.0-2.8 mm) deflection on Millenia, or .06-.16" (1.5-4.0 mm) deflection on 626 at throttle body when installed. If deflection is not as specified, rotate nut on end of cable at throttle body until specified deflection is obtained.
