489.07.0003 RENAULT TRUCKS Injector Sleeve, Cylinder Head

This injector sleeve serves a critical function within the cylinder head assembly, ensuring the precise positioning and sealing of fuel injectors. Manufactured with heavy-duty grade materials, it is designed to withstand high thermal and mechanical stresses during the combustion process, maintaining the integrity of the engine's top-end structure.

489.07.0003 is the OE-equivalent of the RENAULT TRUCKS 5010295301 injector sleeve used in RENAULT TRUCKS heavy commercial vehicles. This component is engineered to meet strict dimensional tolerances required for seamless integration into the cylinder head assembly, ensuring consistent performance under demanding operating conditions.

For workshop technicians performing engine overhauls or maintenance, this part provides a reliable solution for restoring optimal fuel injection paths. It is essential to ensure that the seating surfaces are clean and free of debris during installation to prevent any leakage or pressure loss within the cylinder head system.

Proper inspection of the surrounding cylinder head-port geometry is recommended during replacement to ensure long-term durability and prevent potential combustion irregularities.
