0103 324 Volvo and Renault Trucks Cylinder Head Injector Sleeve

What does an injector sleeve do?

This cylinder head injector sleeve is a critical component that maintains the correct axis and depth for injectors within the cylinder head. It acts as a thermal bridge by conducting heat from the injector to the coolant while maintaining a vital seal between the combustion chamber and the water jacket. This ensures stable performance under high-pressure combustion cycles.

Compatible vehicles and engines

This part is compatible with various heavy commercial vehicle engines, including Volvo models such as FH (FH4/FH5), FM (FM11/FM13), FMX, VHD, VNL, B11R, B13R, and specific engine series like TAD1341-1345VE and TAD1350-1360VE. It also fits Renault Trucks applications including the T, C, K, Magnum, Premium, Kerax models with DTI or DXi engine series.

Maintenance and installation

During engine maintenance or injector replacement, it is recommended to inspect the sleeve and its sealing elements to prevent leaks or combustion gas bypass. Proper installation ensures the injector remains seated correctly against the thermal expansion forces encountered during operation.

Selection guidance

Selecting the correct sleeve is essential for maintaining engine compression and cooling efficiency. Check the compatibility list to ensure exact fitment for your specific engine series.
