2003-2007 Ford Diesel 6.0L Power Stroke Turbochargers
Introduced in 2003, the Ford 6.0L engine came with new turbo technology at that time. A Variable Geometry Turbo (VGT) from Garrett was used instead of the familiar fixed turbo that was used in the 7.3L engines. The VGT turbos are designed to improve throttle response by providing boost control at low and high speeds.
This picture shows a Ford 6.0 turbo opened up. You can see the individual vanes that direct the airflow into or around the turbine wheel. By doing this the turbo will spool faster as the air is directed into the wheel, and will be less restrictive to flow when the air is directed across the wheel tips. This effectively makes a single turbo work like a compound system that has a smaller turbo for quick spool up and a larger turbo for high end power. The vanes control the effective internal size of the housing. These vanes are hydraulically actuated and electronically controlled.
This picture shows the unison ring that controls the movement of the vanes. As with any moving parts, these are subject to wear. Plus to make things worse these parts are in a high temperature, high soot, environment that increases the friction on the parts. Over time steps or groves are worn into the ring and vanes. The vanes will stick over time and the functionality of the turbo decreases.
This picture shows the vanes in an open position. Under high load or high speed conditions the exhaust pressure can become too great. The vanes are commanded open to reduce pressure and prevent turbocharger over speed.
The vanes can be commanded closed which will increase back pressure in the exhaust manifold. This will help drive the exhaust gas through the EGR cooler and EGR valve into the intake manifold. The vanes are also closed to aid in cold ambient temperature warm up. This is the reason the exhaust sound changes when the engine goes into high idle when cold.
This VGT turbo uses engine oil pressure to control the position of the vanes. Shown here is the Variable Geometry Turbocharger Control Valve (VGTCV). This valve is commanded by the PCM based on various engine sensor inputs including the exhaust gas backpressure sensor. Oil is directed to either side of a piston that connects to the unison ring. By pressurizing one side and simultaneously venting the other side, precise control can be achieved of the vanes. If the VGTCV is disconnected, it will default the vanes to the open position.
In low mileage situations where the vehicle is used for short trips, soot can build up quickly. A good cleaning by Huckstorf Diesel can bring these turbos back to proper working condition. In high mileage turbos a cleaning will not fix the wear in the veins and unison ring. A new Garrett turbo is the best option in that case. Only a new Garrett brand turbocharger will include all new parts and all of the engineering updates made to enhance overall durability.
