Garrett New 725390-5006S Turbo AVNT37, Ford 6.0L Early 2003

The Solenoid Control Valve utilizes stricter control parameters to regulate oil flow through the unit. These controls minimize the amount of oil direct to the turbine end seal to reduce turbine seal leakage.

The multiple cycles of the 6.0L application can cause high cycle fatigue of the turbine blades. When a 6.0L turbocharger is reworked it is unknown how many cycles are on the turbocharger which can lead to premature failure. Extended cycles can cause tip failures which can be mistaken for foreign object damage.

All new Garrett 6.0L Replacement turbos contain the up-dated center housing with a machined recess. The machined recess helps vent the moisture that could settle under the unison ring and minimize the corrosion in the contact area between the ring and housing. The machined recess allows toxic liquids to bypass the delicate variable geometry mechanism to reduce buildup and interface friction. Brand new units feature these upgrades for extended turbocharger life on 100% of all units.

A brand new unison ring used with new vanes insures proper clearance thereby assuring superior turbo and engine performance. Eliminate problems associated with salvaged unison rings that increase side clearance with vanes that cause sluggish throttle response.

The leading cause for replacement is corrosion within the VNT Mechanism. Operating conditions of the 6.0L engine cause the turbo VNT mechanism to wear significantly in a normal lifecycle. Rebuilt units that salvage the mechanism can shorten turbo life. All new parts solve these problems.
