This BorgWarner S300V turbo actuator is a professionally remanufactured VGT (Variable Geometry Turbocharger) electronic actuator designed for Navistar International DT466 and DT570 diesel engines. The VGT actuator controls the position of the variable vanes inside the turbocharger, directly affecting boost pressure, fuel efficiency, and overall engine performance. Unlike fixed geometry turbochargers, variable geometry turbos rely on precise actuator positioning to optimize airflow across the full RPM range — making a properly functioning actuator critical to engine health. When this component fails, you may experience loss of power, excessive black smoke, limp mode activation, or fault codes related to turbo boost control. Left unaddressed, a faulty actuator can lead to accelerated turbocharger wear and reduced engine life. All BorgWarner S300V turbo actuators sold by Vortex Turbo have been professionally remanufactured to OEM specifications — not simply tested, cleaned, and repackaged.
All units have been tested to ensure they will pass installation and calibration procedures via compatible diagnostic software.
Includes a 1-year limited warranty — see our Warranty & Return Policy for full details.
Note: Please ensure that the BorgWarner S300V turbo actuator is properly installed and calibrated to your turbocharger via capable diagnostic software if required by the OE.

Why Choose A Remanufactured BorgWarner S300V Turbo Actuator?
OEM replacement actuators can carry a steep price tag, and cheap aftermarket alternatives often fail prematurely due to low-quality internal components and inadequate testing standards. A professionally remanufactured BorgWarner S300V turbo actuator from Vortex Turbo gives you OEM-level reliability at a fraction of the cost of a new unit. Every actuator goes through a rigorous remanufacturing process where all high-wear and failure-prone components are replaced — not just inspected — so you’re getting a unit that performs like new from day one. Our remanufacturing process is performed by diesel electronics specialists with years of hands-on experience with VGT turbo systems, ensuring every unit meets strict performance and durability standards before it ships. Backed by a 1-year limited warranty, it’s a cost-effective solution for fleet operators, independent shops, and owner-operators alike
Product Features
- Professionally remanufactured by experts in the diesel electronics industry — not just a repaired or tested unit that has been cosmetically restored
- Each BorgWarner S300V turbo actuator undergoes a two-stage media blasting process, restoring the housing to a new-look satin finish
- All high wear and failure-prone components have been replaced with OEM or better quality equivalents — not patched or bypassed
- All brand new high-quality Japanese, German, or Swedish bearings installed during remanufacturing
- Brand new interior and exterior bolts/nuts included
Installation & Calibration Notes
Installing an electronic turbo actuator is straightforward for experienced diesel technicians. The actuator mounts either directly to the turbocharger housing or a connected pedestal and connects via the OEM wiring harness. Depending on your specific application and the diagnostic software available, calibration of the actuator position may be required after installation per OE specifications. We recommend using compatible diagnostic tools such as International ServiceMaxx, Cummins Insite, or equivalent software to complete the calibration procedure and clear any related fault codes. If you have questions about compatibility or installation, contact Vortex Turbo before ordering.
