This is the Alliant Power AP63459, a new EGR valve, not a rebuilt one, for the International / Navistar VT365 6.0L V8, model years 2004 to 2006. It replaces International 1846296C91. It is a direct replacement part for the factory exhaust gas recirculation system.
EGR valves on these engines stick with soot and oil. A stuck valve gives a rough idle, black smoke, low power or EGR position codes. Look at the EGR cooler and the intake for coolant or heavy oil before you fit a new valve, because whatever fouled the old one will foul the new one.
Confirm Fitment Before You Order
This valve is listed for the 2004 to 2006 International VT365 only. The Ford 6.0L Power Stroke is a sister engine, but its EGR valve is sold under different part numbers and we have not confirmed this one for a Ford pickup. Send us your engine serial number and the International number on your old valve (1846296C91) before you order. Call 530-668-0818 and we will confirm the exact match at no charge before anything ships.
