This is the Alliant Power AP90914, a BorgWarner S300V variable geometry turbocharger for the International DT466 and DT570 built from 2004 to 2008, remanufactured by Alliant Power. It is a complete turbo with the electronic actuator already fitted, and it is the low mount version (S300V110). It replaces BorgWarner 173900, 179030, 473900 and 479030 and Navistar 1842337C91 through C95, 1842582C91 through C98, 1870932C91 through C94, 5010314R91 through R96, 5010580R91 and 5010581R91. Catalogs also list it under the MaxxForce DT name and date the turbo from 2003.
Low boost, a boost control or actuator fault code, a sticking vane mechanism, 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 and a split charge air cooler before you condemn the turbo. A refundable core applies to this remanufactured unit.
Confirm Fitment Before You Order
The S300V was built in several versions that look alike. BorgWarner 179030 and 173900 are this unit. BorgWarner 179031, 173901 and 173902 are a different S300V with their own Navistar numbers and take a different part number, and the B2UV turbos used on the DT466 and MaxxForce DT are different again. Heavy and medium duty turbos are matched by the number on the turbo tag, so read the BorgWarner and Navistar numbers off your old unit before you order. Send us the tag numbers and the engine serial number. Call 530-668-0818 and we will confirm the exact match at no charge before anything ships.

Find out why the old turbo failed before you fit this one. Change the engine oil and filter, check the oil feed and drain lines, prime the turbo with clean oil, and clean or replace the charge air cooler if the old turbo passed oil or broke up. Follow the truck maker’s procedure for the actuator after fitting.
