Description
What does a cylinder head injector sleeve do?
The cylinder head injector sleeve acts as a critical dry housing tube fitted into the cylinder head to separate the injector from the coolant passages in heavy-duty diesel engines. It keeps the injector on its correct axis and at a fixed depth while maintaining the essential seal between the combustion chamber and the water jacket. By conducting heat from the injector to the coolant, it also functions as a vital thermal bridge.Compatible Volvo engines and models
This component is designed for use in various Volvo engine families, including TD70, TD71, TD100, TD101, TD102, TD103, D10A, D12A, TD120, TD121, TD122, and TD123. It is compatible with Volvo F7, F10, F12, FL10, FL12, N10, N12, NL10, NL12, B10B, B10M, and B12 models. These parts are essential for maintaining combustion integrity in heavy commercial vehicle applications.Installation and maintenance guidance
During maintenance or injector replacement, technicians should inspect the sleeve for signs of thermal stress or erosion. Proper installation is critical to ensure the sleeve seats correctly within the cylinder head to prevent coolant leakage or combustion gas bypass. When replacing these components, it is recommended to check all associated sealing elements to ensure a complete and reliable repair.Troubleshooting and selection
Always verify fitment against specific engine designations to ensure correct thermal conductivity and axial alignment within the cylinder head assembly.OE cross-reference
