This is the BorgWarner 479032, an S300V variable geometry turbocharger remanufactured by BorgWarner, model S300V111. It is the low mount turbo for the International / Navistar DT466 7.6L inline six, which some catalogs also file under MaxxForce DT466, and it comes as a complete unit with the electronic actuator fitted. It replaces Navistar 1842216C91 to C95, 1842580C91 to C98, 1870931C91 to C94, 5010313R91 to R96, 5010574R91 and 5010575R91. The new version of the same turbo is BorgWarner 179032, with the same fitment. Heavy and medium duty turbos are matched by the number on the turbo tag, not by engine model alone.

Low boost, a boost control or actuator fault code, sticking vanes, oil in the charge pipes or shaft play are the usual reasons this unit comes off. Soot in the vanes and a failed actuator give the same low power complaint, so check for exhaust leaks, a split charge air cooler and wiring faults before you condemn the turbo. Find out why the old one failed as well: check the oil feed and drain, the air filter and the intake piping. A refundable core applies, so keep your old turbo complete with its actuator.

Frequently Asked Questions

Does the 479032 come with the actuator?

Yes. Catalogs list it as a complete S300V turbocharger with the electronic actuator fitted. Keep your old turbo complete, actuator included, for the core return.

What Navistar numbers does the 479032 replace?

Navistar 1842216C91 to C95, 1842580C91 to C98, 1870931C91 to C94, 5010313R91 to R96, 5010574R91 and 5010575R91. It also takes the place of BorgWarner 173941.

Is the 479032 the same as the 12639900001 or the 479030?

No. The 479032 is the low mount S300V111. The 12639900001 is a mid mount B2UV, and the 479030 is another S300V with its own Navistar numbers. Go by the number on your turbo tag.

Is it new or remanufactured, and is there a core?

It is remanufactured by BorgWarner, and a refundable core applies. The new version of the same turbo is BorgWarner 179032.
