489.07.0004 Injector Sleeve for Volvo and Renault Trucks

What does an injector sleeve do?

The cylinder head injector sleeve is a vital component that serves as a dry housing tube within the cylinder head. It maintains the injector at the correct axis and fixed depth while providing a critical seal between the combustion chamber and the coolant passages. By conducting heat from the injector to the coolant, it also acts as an essential thermal bridge for heavy-duty diesel engines.

Vehicle and engine compatibility

This component is compatible with a wide range of Volvo and Renault Trucks engines, including Volvo FH13, FH16, FM11, FM13, FMX, VHD, VNL, B11R, B13R, and TAD1341-1345VE engines (D13, D16E, D16G, D11A, D11B, D13A, D13B, D13C). It is also fitted to Renault Trucks Kerax (DXi11), Magnum (DXi13), and Premium (DXi11, DXi13) models.

Installation and maintenance guidance

When performing engine maintenance or injector replacement, technicians should inspect the sleeve for signs of thermal fatigue or seal degradation. It is often recommended to replace the sleeve alongside its lower sealing elements to prevent combustion leaks or coolant contamination. Ensuring correct installation is vital to maintain proper injector alignment.
