This housing is listed for Volvo D12A 425HP applications, including the FH12 truck. It is also associated with Volvo D12C Tier II engines in A40D articulated haulers and Volvo DH12D truck configurations. These paths serve as reference clues for fitment verification.

Verify mounting flange patterns and inlet port dimensions to ensure the replacement application matches your existing turbocharger setup.

Technical Notes

The GT4594 turbocharger model is a fixed-geometry unit, meaning it does not use variable turbine geometry or adjustable vanes. This housing supports the compressor side of the assembly, directing airflow into the engine intake. Because no OEM reference numbers are listed in the input data, buyers must verify fitment using the part number 449858-0012 and the specific engine code. For Volvo D12A 425HP applications, confirm the turbo model matches your existing setup. Technical fitment support is available to assist with verification before ordering.

Product FAQ
