489.03.0010 Volvo Compatible Injector Sleeve

This injector sleeve is a critical dry housing tube fitted into the cylinder head that separates the injector from the coolant passages in diesel engines. By maintaining the correct axis and fixed depth for the injector, it ensures a reliable seal between the combustion chamber and the water jacket. Additionally, it acts as a thermal bridge by conducting heat away from the injector to the coolant.

This component is designed for use in various Volvo engines, including the TD100, TD101, TD120, and D12A series. It is highly compatible with Volvo F7, F10, F12, FL10, FL12, N10, N12, NL10, NL12, B10B, B10M, and B12 heavy commercial vehicle models. These parts are essential for maintaining engine compression and preventing coolant contamination within the combustion chamber.

During engine maintenance or injector replacement, technicians should inspect the sleeve for signs of thermal stress or erosion. Proper installation requires ensuring the sleeve is seated correctly to maintain its seal against the water jacket. When replacing these components, it is recommended to follow manufacturer-specific torque guidelines to ensure long-term durability under high-pressure combustion cycles.
