DT466 high pressure pump procedures
This section explains removing the IPR valve with a 28 mm (1-1/8 in.) deep-wall socket, draining the reservoir through the Engine Oil Temperature sensor port with vacuum tool ZTSE2499, and removing the two capscrews securing the pump to the front cover. Front- and mid-mounted ICP sensor layouts and supply manifold warpage checks are covered. Figures and numbered callouts illustrate each operation step by step, and every fastener is tightened to the special torque value published in the companion “Specifications, Special Torque Values, and Service Tools” section (publication EGES2101).
Applicable truck models
It applies to International DT466E and 530E diesel engines and notes procedure differences for serial numbers 988150 and below versus 988151 and up. Drain the reservoir before removal. For official model information, see the International Trucks (Navistar) website.
Who needs this DT466 high pressure pump
Technicians chasing injection-control-pressure faults use these steps to service the IPR valve and replace the high-pressure oil pump. Because this is one chapter of the complete International DT466 and DT530 (2000-2003) service manual set, most workshops download it alongside the diagnostic manual, the DTC list and the specification volume so the repair, testing and reference material stay together.
