Under severe heavy-duty thermal cycling and soot exposure, these factory cores succumb to fatigue cracking and sulfurous acid pitting. Internal failure breaches the coolant jacket, forcing pressurized coolant into the exhaust stream. This causes white exhaust smoke, rapid coolant loss without external puddling, elevated combustion temperatures, and persistent EGR diagnostic trouble codes that can force limp-mode derates.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis replacement round-style cooler is manufactured with reinforced stainless steel tubing designed to withstand extreme diesel thermal shock and corrosive exhaust soot. Measuring approximately 11.5 inches in length, the assembly features precision TIG-welded ends that resist thermal fatigue far better than factory brazing. By providing consistent heat transfer to the cooling jacket, it prevents hot spots and preserves intake air density. Direct-fit alignment ensures leak-free integration with the engine's coolant circuit, replacing OEM units marked \u003cstrong\u003e1871733C92\u003c\/strong\u003e and \u003cstrong\u003e1871733C93\u003c\/strong\u003e without modifications.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 Round Stainless Steel EGR Cooler (approx. 11.5 in)\u003c\/li\u003e\n  \u003cli\u003e1 Coolant Tube\u003c\/li\u003e\n  \u003cli\u003e1 Mounting Bracket Clamp\u003c\/li\u003e\n  \u003cli\u003e2 Hose Clamps\u003c\/li\u003e\n  \u003cli\u003e1 Exhaust Ring Gasket\u003c\/li\u003e\n  \u003cli\u003e1 Triangle Flange Gasket\u003c\/li\u003e\n  \u003cli\u003e3 O-Rings\u003c\/li\u003e\n  \u003cli\u003e3 Fastener Bolts\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cdiv style=\"overflow-x: auto; margin-bottom: 20px;\"\u003e\n  \u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px; min-width: 300px;\"\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eFitment\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e2006-2007 International RXT\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eEngine \/ Chassis\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e\n\u003cstrong\u003eDT570 9.3L\u003c\/strong\u003e \/ \u003cstrong\u003eXT Platform\u003c\/strong\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eStock Output\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e310 hp \/ 950 lb-ft\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eReplaces OEM Part #\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e1871733C92, 1871733C93, Dorman 904-5020, EGR733\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n\u003c\/div\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2006 International RXT 9.3L Navistar DT570 \/ HT570 Diesel\u003c\/li\u003e\n  \u003cli\u003e2007 International RXT 9.3L Navistar DT570 \/ HT570 Diesel\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions \u0026amp; Fitment Warnings\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the XT Platform RXT?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2006-2007 International RXT equipped with the \u003cstrong\u003eDT570 9.3L\u003c\/strong\u003e engine; verify your original core matches the 11.5-inch round style before ordering.\u003c\/p\u003e\n\n\u003ch4\u003eDo I need to bleed the cooling system after replacement?\u003c\/h4\u003e\n\u003cp\u003eYes, the cooling system must be fully drained, refilled, and bled of air pockets during installation to prevent localized hot spots and immediate thermal stress on the replacement core.\u003c\/p\u003e\n\n\u003ch3\u003eThe International Hauling Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered for high-tonnage hauling and demanding highway cycles, this emissions-compliant heat exchanger ensures stable operating temperatures and leak-free reliability under sustained heavy trailer loads.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67610979008760,"sku":"DS-E11PQYBMA","price":199.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/egr-cooler-kit-for-international-rxt-2006-2007-9-3l-1.jpg?v=1791567729","url":"https:\/\/performancechiptuning.com\/products\/egr-cooler-kit-for-international-rxt-2006-2007-9-3l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
