What our customers say
Detroit Actuators FAQs
The actuator controls the variable geometry system inside a VGT turbocharger. By changing vane position, the system helps regulate exhaust flow and boost pressure across different engine speeds and loads.
Many electronic turbo actuators can be professionally rebuilt depending on their condition. The process can include inspection, cleaning, replacement of damaged components, calibration, and operational testing.
Proper actuator calibration is important because the actuator must correctly correspond with the VGT mechanism's position. Incorrect calibration can cause poor turbo operation or fault codes.
The safest method is to match the actuator and turbocharger part numbers. Your engine model, engine serial number, VIN, and photos of the existing actuator can also help STR confirm the correct application.
Some rebuilt actuators may require a refundable core deposit. Check the individual product listing for the specific core requirements before ordering.
