This is the BorgWarner 479515, the high-pressure turbocharger for the 2008 to 2010 Ford 6.4L Power Stroke, remanufactured by BorgWarner, the original turbo maker for this engine. It comes with the electronic actuator. The 6.4L runs two turbos in series, the BorgWarner V2S system, and this is the high-pressure half only. It replaces Ford 8C3Z-6K682-BARM and 8C3Z-6K682-DARM, Navistar 1848303C3 and 4307200R1, and BorgWarner 179515 and 176466. A refundable core applies.

The high-pressure turbo is the one that carries the actuator, so it is the one that usually sets the turbo control and boost faults. Slow spool, low boost, a sticking actuator or oil at the turbo are the common reasons it comes off. If the low-pressure turbo has shaft play too, the complete set, BorgWarner 479514, replaces both in one job.

Specifications

Fits / Applications

• 2008 to 2010 Ford Super Duty, 6.4L Power Stroke
• High-pressure turbo only, with electronic actuator
• For both turbos as a set, see BorgWarner 479514

Use new gaskets between the two turbos and at the engine, check the oil feed and drain, and clean the charge air cooler and pipes before the first start. A turbo that failed from oil starvation or debris will fail again if the cause is not fixed.
