- Thoroughly clean the area around the fuel injectors to prevent contamination.
- Carefully disconnect the fuel lines and electrical connectors from the target injector.
- Remove the injector retaining bolt and gently extract the injector.
- Using a specialized injector sleeve puller tool, remove the old sleeve from the cylinder head.
- Clean the sleeve bore meticulously, ensuring no debris or old sealant remains.
- Place the new seals and O-rings from the kit onto the new injector sleeve.
- Using an appropriate installation tool, press the new sleeve into the cylinder head until it is fully seated.
- Reinstall the injector, torque its retainer to the manufacturer's specified value, and reconnect fuel lines.
- Reconnect the battery, start the engine, and carefully inspect for any fuel or coolant leaks around the injector.
Troubleshooting & FAQ
How do I know if my injector sleeves are failing?
Common symptoms of a faulty injector sleeve include finding fuel in the engine coolant reservoir, coolant contamination in the fuel, rough running conditions, or white smoke from the exhaust. A visual inspection during an injector service may also reveal cracks or heavy corrosion.
Is a special tool absolutely necessary for this job?
Yes, using the correct injector sleeve removal and installation tools is strongly recommended. Attempting to remove the sleeve with makeshift tools can easily damage the precision-machined bore in the cylinder head, leading to very costly repairs.
What is the main advantage of buying this kit?
This kit provides a complete solution by including the injector sleeve and all the necessary seals (retainer, sealing ring, O-ring) required for a single injector replacement. This ensures you have all components on hand, preventing leaks and ensuring a durable repair.
Can I reuse any of the old seals or the retainer?
No. Seals and O-rings are single-use components that compress and deform to create a seal. Reusing them will almost certainly result in fuel or coolant leaks. Always use all the new components supplied in the kit.
OEM vs. Aftermarket?
This listing is an aftermarket replacement (not OEM). Built to OEM-level specifications with comparable materials. Manufactured in an ISO 9002 facility, batch-inspected for consistency.
