Cummins ISC ISL EPA10 Holset HE431VE VGT Actuator

Please call us at 682-323-5959 to confirm current stock availability.

This remanufactured Cummins ISC ISL HE431VE VGT actuator is a professionally rebuilt Holset variable geometry (VGT) electronic actuator for EPA10 Cummins ISC 8.3L and ISL 8.9L engines running the HE431VE turbocharger. The actuator controls the turbocharger’s VGT vane position, regulating boost pressure, throttle response, and emissions performance across the full RPM range.

When a Cummins ISC ISL HE431VE VGT actuator fails, common symptoms include limp mode, low power, poor fuel economy, excessive smoke, turbo lag, and fault codes tied to VGT actuator position or boost pressure. Replacing a worn or faulty unit with this remanufactured Cummins ISC ISL HE431VE VGT actuator restores correct vane control without the expense of replacing the entire turbocharger.

Note: All VGT actuators must be calibrated to your turbocharger prior to operation using Cummins INSITE or another capable diagnostic tool. Calibration procedures may vary depending on the vehicle application and diagnostic tool used.

Includes a 1-year limited warranty — see our Warranty & Return Policy for full details.

Why Choose A Remanufactured Cummins ISC ISL HE431VE VGT Actuator?

New OEM Holset actuators carry a steep price tag, and low-cost imitations frequently fail or will not hold calibration. A remanufactured Cummins ISC ISL HE431VE VGT actuator from Vortex Turbo delivers OEM-level reliability at a fraction of the cost of a new unit. Every actuator is rebuilt by diesel electronics specialists and ships with a mounting/installation kit — a dependable choice for owner-operators, fleets, and independent diesel repair shops.

Installation & Calibration Notes

The Cummins ISC ISL HE431VE VGT actuator bolts directly to the turbocharger and connects to the OEM wiring harness. After mechanical installation, the actuator must be calibrated to the specific turbocharger using Cummins INSITE or a comparable diagnostic tool — an uncalibrated actuator will not correctly control vane position. Contact Vortex Turbo before ordering if you are unsure whether this actuator matches your turbocharger.
