Note. Ensure injector connectors are marked for installation reference prior to removal. Performance and emissions will be affected if injector connectors are not positioned correctly.
Removal
- On 2000 models, disconnect negative battery cable. Drain cooling system. Disconnect IAT and MAF sensor connectors. Remove air intake duct and air cleaner assembly.
- On 2001 models, drain cooling system. Remove throttle body. Remove fuel injectors.
- On all models, remove fuel rail covers. Relieve fuel pressure. See «FUEL PRESSURE RELEASE»(ref-97422-S10869845392001050700000) . Disconnect fuel lines from fuel rail. Remove vacuum and crankcase vent hoses. Remove throttle body coolant outlet hose from throttle body. Disconnect fuel injector connectors. Disconnect throttle position sensor connector. Disconnect knock sensor electrical connector. Label and disconnect all remaining electrical connectors. Remove knock sensor pigtail from fuel rail stop bracket. Remove PCV valve pipe from left and right valve covers. Remove intake manifold bolts, and fuel rail stop bracket. Note location of fuel rail ground strap for reassembly. Remove engine coolant air bleed hose from throttle body. Remove intake manifold bolts. Remove intake manifold.
Installation
| CAUTION | Ensure fuel rail stop bracket is installed onto engine assembly. Fuel rail stop bracket serves as a protective shield for fuel rail in event of a frontal crash. If fuel rail stop bracket is not installed, and vehicle is involved in a frontal crash, fuel could be sprayed, possibly causing a fire and personal injury from burns. |
To install, reverse removal procedure. Tighten bolts to specification. See TORQUE SPECIFICATIONS. (Scheme 4) Fill and bleed cooling system. See COOLING SYSTEM BLEEDING.
