Description
What does an injector sleeve do?
This cylinder head injector sleeve functions as a critical dry housing tube that is fitted into the cylinder head to isolate the injector from coolant passages. By maintaining the injector on its correct axis and at a fixed depth, it prevents leaks between the combustion chamber and the water jacket. Additionally, it serves as a thermal bridge, conducting heat away from the injector to the coolant to ensure stable engine operation.Compatibility and fitment
This component is specifically designed for Scania engines. It is an essential part for maintaining combustion efficiency and preventing coolant contamination within the engine system. The sleeve helps maintain structural integrity under high thermal loads common in heavy commercial vehicle applications.Installation and maintenance
For professional technicians, ensuring a precise fit during installation is vital to prevent pressure loss or misalignment. When performing injector maintenance or cylinder head service, it is recommended to inspect the sleeve and its sealing elements for any signs of wear or thermal fatigue to ensure long-term reliability.Engine performance and reliability
Proper selection of this component ensures that the injector remains securely seated despite the intense vibrations and thermal expansion cycles experienced during engine operation.OE cross-reference
489.04.0003 (Cylinder Head Injector Sleeve) is the equivalent of the Scania OE numbers. This part directly replaces Scania OE numbers 1524330, 1865117.Other OEMs
