Safety Warning: Diesel fuel systems operate under extreme pressure. Ensure the engine is completely cool and pressure has been relieved from the fuel system before beginning work. Always wear appropriate safety equipment including eye protection and gloves.
Step-by-Step Replacement Procedure
Step 1: Prepare the Work Area
Ensure you have adequate lighting, ventilation, and a clean workspace. This prevents contamination of the fuel system and makes it easier to track small components. Allow at least 3-4 hours for the complete procedure.
Step 2: Disconnect the Battery
Locate the negative battery terminal and disconnect it first to prevent electrical shorts or accidental system activation during the repair. Secure the cable away from the terminal.
Step 3: Remove the Engine Cover
Using the appropriate socket wrench, remove the bolts securing the engine cover. Carefully lift the cover away and store it in a safe location to prevent damage.
Step 4: Remove the Air Intake Duct
Loosen the clamps on both ends of the air intake duct using a screwdriver. Carefully remove the duct and set aside, creating workspace access to the injectors.
Step 5: Disconnect the Fuel Lines
Using the appropriate Torx screwdriver, carefully disconnect the high-pressure fuel lines from each injector. Be prepared for some residual fuel spillage. Place a rag underneath to catch any drips.
Important: Label each fuel line connection point to ensure correct reassembly later.
Step 6: Disconnect the Electrical Connections
Locate and disconnect the electrical connectors from each injector. Some may require a release tab to be pressed while others might need a gentle prying motion with needle nose pliers.
Step 7: Remove the Old Injectors
Using the appropriate socket or wrench, remove the bolts securing the injector hold-down brackets. Carefully extract the injectors, using a gentle rocking motion if they're stuck. Never force an injector as this can damage the cylinder head.
Step 8: Clean the Injector Seating Area
Using a wire brush and clean rags, thoroughly clean the injector bores in the cylinder head. Remove all carbon deposits, old seals, and debris. A perfectly clean seating surface is essential for proper sealing.
Step 9: Install the New Injectors
Place new copper washers/seals if required. Carefully insert each new C11 C13 injector 2490713 into its bore, ensuring it seats fully and squarely. Install and torque the hold-down brackets to the manufacturer's specifications using a torque wrench.
Step 10: Reconnect the Electrical Connections
Reattach the electrical connectors to each injector, ensuring they click firmly into place. Verify all connections are secure by gently tugging on them.
Step 11: Reconnect the Fuel Lines
Carefully reconnect the high-pressure fuel lines to each injector, following your earlier labeling. Tighten the connections to the specified torque using the appropriate tool.
Step 12: Reinstall the Air Intake Duct
Replace the air intake duct and secure the clamps at both ends, ensuring proper alignment and a tight seal.
Step 13: Replace the Engine Cover
Reinstall the engine cover and secure all mounting bolts to the proper torque specifications.
Step 14: Reconnect the Battery and Test
Reconnect the negative battery terminal. Prime the fuel system according to the manufacturer's instructions, then start the engine and check for leaks. Monitor engine performance during a test drive, listening for unusual noises or checking for error codes.
DIY Success Tip: After installation, the engine may run roughly for the first few minutes as air is purged from the system. If rough running persists beyond 5 minutes or if any warning lights appear, shut down the engine and recheck all connections.
