489.03.0001 Mack and Volvo Injector Sleeve

What does an injector sleeve do?

The cylinder head injector sleeve acts as a critical housing tube within the cylinder head, separating the fuel injector from the engine coolant passages. By maintaining the injector at a fixed depth and precise axis, it prevents leaks between the combustion chamber and the water jacket. Furthermore, it serves as a vital thermal bridge, conducting heat away from the injector to the coolant to ensure stable combustion temperatures.

Engine compatibility and fitment

This component is specifically designed for a wide range of heavy commercial vehicle engines. It is compatible with Mack models including Anthem, Granite, LR, MRU, Pinnacle, Terrapro, and Titan engines (MP7, MP8, MP10). It is also fitted to Volvo engines such as FH12 through FH16, FM series, FMX, NH12, VHD, VNL, and B-series (D10 through D16 engine families), as well as Renault Trucks Kerax and Magnum models.

Installation and maintenance

For professional workshop technicians and fleet managers, ensuring proper seating during installation is vital to prevent combustion gas bypass. When replacing this component during injector service or cylinder head maintenance, it is recommended to inspect the sealing surfaces to maintain system integrity. Vaden Original parts are manufactured to meet high-strength requirements for demanding engine environments.
