DescriptionWith the Variable Geometry Technology (VGT) turbocharger in the '07.5-'12 Ram Turbo Diesel trucks, everything changed when it came to servicing it. To work on it you needed training, expensive tools and you couldn't test the actuator, so as a DIY-er truck owner you were left with replacing the turbo which is expensive.
City Diesel worked to fix this. Step one was to develop an actuator tester that anyone could use. Shortly after they released it, more affordable rebuilt turbochargers started showing up. However, there was still a problem because the actuator has to be calibrated to the turbocharger and you were not able to simply replace an actuator. This means you either have to pay a fee to get the actuator calibrated at a shop that has the correct equipment (average price $200) or buy the entire turbocharger even if the actuator was the only problem.
The cost-effective solution: the creation of a new actuator. It is what we call a half-shell: you replace all the electronics, including the circuit board and motor, and reusing the half of your actuator that only contains gears (the "gearbox"). There is no calibration required and no complicated installation. Again, what this means to you is that you have a viable, cost-effective option for replacing your actuator when you have a problem.
- Cost effective solution - no need to replace entire turbo.
- No need for expensive tools or a trip to the dealership calibration.
- It wipes the vanes/self-testing on every key cycle, preventing soot and carbon buildup.
- The actuator motor has almost twice the torque: This makes it more difficult for the vanes to freeze up and gives you faster throttle response.
- The actuator was designed from the beginning to work well with EFI-live aftermarket tuners.
- Replacement actuator to turbo mounting gaskets included.
- Drain the coolant
- Remove the four 5mm Allen-head bolts holding the actuator to the turbo.
- Check to make sure the gear that the actuator moves on the turbo is free.
- Separate the actuator shell by removing the 4 torx bit screws holding it together.
- Join our actuator to your gearbox with the included screws. (It is very important that the turbo be completely dry before installing the new actuator.If not, and the circuit board is fried, we WILL void the warranty)
- Bolt the assembly back on to your turbo with the included new 5mm Allen-head bolts.
- Replace the coolant.
