Technical Notes

The H2D turbocharger is a fixed-geometry unit typically used in diesel truck applications. For this 3528811 replacement, verify the turbine and compressor housing orientation against your existing unit. Confirm that the OEM reference numbers, such as 478439 or 478440, match the markings on the old turbocharger. Check the shaft for excessive play and inspect the compressor wheel for damage before deciding between a new unit and a rebuild. If technical drawings are needed, provide the part number 3528811 and the specific Volvo engine code to support accurate fitment verification.
