489.03.0003 VOLVO Injector Sleeve, Cylinder Head

The 489.03.0003 product serves a critical role within the engine system, specifically acting as an injector sleeve for the cylinder head. This component is engineered to maintain precise tolerances and withstand the intense thermal and pressure environments found in heavy commercial vehicle engines, ensuring consistent fuel injection performance.

489.03.0003 is the OE-equivalent of the VOLVO 273821 and 276130 injector sleeve used in VOLVO heavy commercial vehicles. This part is designed to meet strict technical specifications to ensure seamless integration with existing engine architectures, preventing leaks and maintaining compression integrity.

For workshop technicians performing engine overhauls or maintenance, this part offers a reliable solution for maintaining engine efficiency. It is essential to ensure that all seating surfaces are clean during installation to prevent any misalignment within the cylinder head assembly. Regular inspection of the injector seating area is recommended during routine service intervals to ensure the longevity of the component.

Using high-strength components like this one helps prevent common issues related to injector seat wear and combustion leaks, thereby reducing unexpected downtime for fleet operators.
