Fuel Rail & Injectors: Installation
- If installing injector on fuel rail, replace retaining clip or "O" ring on injector if damaged. Lubricate "O" ring at top of injector with engine oil.
- Ensure retaining clip is installed in top slot on injector. Install injector on fuel rail, using care not to damage the "O" ring.
- To install remaining components, reverse removal procedure. Use NEW gaskets. Ensure injector holes are clean before installing injectors. Replace "O" ring at bottom of injector if damaged.
- Lubricate "O" ring at bottom of injector with engine oil before installing fuel rail with injectors. Tighten fuel rail bolts to specification. See TORQUE SPECIFICATIONS .
- Tighten intake manifold-to-cylinder head bolts to specification, starting at the center and working outward. See TORQUE SPECIFICATIONS .
- Install fuel supply line on chassis fuel supply line using proper procedure. See FUEL LINE DISCONNECT FITTINGS under FUEL SYSTEM.
- Air must be bled from cooling system when filling cooling system. Disconnect electrical connector at engine coolant temperature sensor. Engine coolant temperature sensor is located near thermostat housing and contains a Black/Light Blue wire and a Tan/Black wire in the electrical connector.
- Remove engine coolant temperature sensor. Fill cooling system until coolant flows from engine coolant temperature sensor opening.
- Install and tighten engine coolant temperature sensor to specification. See TORQUE SPECIFICATIONS . Finish filling cooling system. Install electrical connector. Using scan tool and scan tool manufacturer's instructions, perform ASD FUEL SYSTEM TEST and check for fuel leaks.
