Dorman 668-100 turbocharger actuator for the 2013-2018 Ram 2500 6-cylinder 6.7L and other vehicles is a remanufactured actuator that adjusts the variable geometry turbocharger (VGT) to control boost pressure.
- Original solderless compliant pins can separate from the printed circuit board assembly (PCBA) under heat and vibration
- Soldered compliant pins give a more secure connection to the PCBA
- Remanufactured at an advanced electronics facility to the highest industry standards
- Tested to help restore factory-spec turbo boost pressure
Quick facts
- Part: Dorman 668-100 turbocharger actuator
- Fits: 2013-2018 Ram 2500 6-cylinder 6.7L and other vehicles
- Material: Aluminum, plastic
- Condition: Remanufactured
Low turbo boost, a loss of power or a check engine light can mean the actuator is failing, though the turbocharger itself or the wiring to it can produce those signs too, so trace the fault first. The engine takes one actuator, and this listing is one.
Fits
The vehicles it fits include the 2013-2018 Ram 3500 6-cylinder 6.7L and the 2013-2018 Ram 4500 6-cylinder 6.7L, plus the 2013-2018 Ram 2500 6-cylinder 6.7L named above. It is built for specified Ram trucks with 6.7L I6 turbodiesel engines.
