Description
What does an injector sleeve do?
The cylinder head injector sleeve functions as a dry housing tube that is fitted into the cylinder head to separate the injector from the coolant passages. This component is vital for maintaining the seal between the combustion chamber and the water jacket while acting as a thermal bridge to conduct heat away from the injector. By keeping the injector on its correct axis and at a fixed depth, it ensures stable combustion performance in heavy-duty diesel engines.Compatibility and application
This part is specifically compatible with Mercedes-Benz vehicles. It serves as a reliable replacement to ensure engine integrity and prevent coolant leakage into the combustion chamber. The sleeve is engineered to withstand extreme thermal cycles and high pressure within the cylinder head assembly.Installation and maintenance
When performing injector maintenance or cylinder head service, technicians should inspect this component for signs of wear or improper seating. Ensuring a clean bore during installation is critical for maintaining a proper seal. Consult your authorized distributor to ensure correct fitment for your specific engine model.Troubleshooting guidance
Regular inspection of the injector seating area can prevent more extensive engine damage caused by coolant contamination or loss of compression.OE cross-reference
