489.03.0014 Injector Sleeve Compatible with Volvo and Renault Trucks

What does an injector sleeve do?

The cylinder head injector sleeve is a dry housing tube fitted into the cylinder head that separates the injector from the coolant passages in diesel engines. It keeps the injector on the correct axis and at a fixed depth, while maintaining the seal between the combustion chamber and the water jacket; by conducting heat from the injector to the coolant, it also acts as a thermal bridge.

Compatible vehicles and engines

This component is compatible with Volvo engines such as D12, D13, D16, D10, and D11 series across models like FH, FM, FMX, VHD, and VNL. It is also fitted to Renault Trucks engines including DXi11, DXi12, and DXi13 found in Kerax, Magnum, and Premium models. Additionally, it serves Mack engines like Anthem, Granite, LR, MRU, Pinnacle, Terrapro, and Titan.

Installation and maintenance

For workshop technicians performing engine overhauls, it is recommended to inspect the sleeve for any signs of erosion or cracks during injector removal. Replacing the sleeve alongside its sealing elements ensures a reliable seal between the combustion chamber and the water jacket to prevent coolant contamination.
