489.03.0009 Volvo Injector Sleeve Compatible

This injector sleeve acts as a 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 at a fixed depth while maintaining a critical seal between the combustion chamber and the water jacket. It also serves as a thermal bridge, conducting heat away from the injector to the coolant to ensure stable operating temperatures.

This component is engineered for compatibility with a wide range of Volvo engines, including the TD100, TD101, TD102, TD120, TD121, TD122, TD70, TD71, TD103, D10A, TD123, D12A and various B-series models. It is specifically designed for use in heavy commercial vehicle applications such as Volvo F7, F10, F12, FL10, FL12, N10, N12, NL10, NL12, B10B and B10M series trucks.

For professional workshop technicians and fleet managers, ensuring proper installation is vital. The sleeve must be seated correctly to prevent leaks or shifting off-axis during high-pressure combustion cycles. When performing injector maintenance or cylinder head service, it is recommended to inspect the sleeve for wear and ensure a clean mating surface to maintain optimal sealing performance.

Consult your authorized distributor to check the compatibility list.
