Prolonged exposure to high-temperature exhaust gas creates intense thermal stress between the internal coolant channels and exhaust tubes. Over operational hours, microscopic stress fractures develop across thin-wall internal core welds, leading to internal coolant loss into the exhaust stream, persistent white smoke, uncommanded cooling system pressurization, elevated cylinder head temperatures, and recurrent EGR differential pressure trouble codes.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis replacement EGR cooler is engineered with heavy-gauge, corrosion-resistant stainless steel construction to withstand severe thermal expansion without core degradation. Measuring approximately 11.5 inches in length with an OEM-spec round profile, the TIG-welded assembly maintains uniform heat dissipation across internal gas passages to drop exhaust gas recirculation temperatures reliably. The direct-fit design matches factory mounting locations precisely and includes a dedicated coolant tube, support bracket, and a full set of high-durometer O-rings and composite flange gaskets to eliminate leak points during high-load vocational operation.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 EGR Cooler (Round Style, Stainless Steel, 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 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;\"\u003e2004-2006 International 7300\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;\"\u003eDT466 (7.6L) \/ WorkStar Medium Duty\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;\"\u003e210-300 hp \/ 520-860 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\u003e2004 International 7300 Base Medium-Duty Vocational Truck (7.6L DT466 Turbo Diesel)\u003c\/li\u003e\n  \u003cli\u003e2005 International 7300 Base Medium-Duty Vocational Truck (7.6L DT466 Turbo Diesel)\u003c\/li\u003e\n  \u003cli\u003e2006 International 7300 Base Medium-Duty Vocational Truck (7.6L DT466 Turbo 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 WorkStar Medium Duty 7300?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2004-2006 International 7300 equipped with the \u003cstrong\u003eDT466\u003c\/strong\u003e 7.6L inline-six diesel engine using the 11.5-inch round-style core; always verify your stamped OEM casting number prior to ordering.\u003c\/p\u003e\n\n\u003ch4\u003eDo I need to bleed the cooling system after installing this EGR cooler?\u003c\/h4\u003e\n\u003cp\u003eYes, technicians must completely drain, flush, refill, and purge trapped air from the cooling system to prevent localized hot spots that can crack new cooler cores and cylinder heads.\u003c\/p\u003e\n\n\u003ch3\u003eThe International WorkStar Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered for high-GVWR commercial applications, severe-duty dump cycles, and heavy municipal hauling, this stainless replacement assembly restores thermal equilibrium to keep your vocational fleet moving without unscheduled downtime or costly cylinder head overheating.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67610977534200,"sku":"DS-EAYA1VQF4","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-7300-2004-2006-7-6l-1.jpg?v=1791567566","url":"https:\/\/performancechiptuning.com\/products\/egr-cooler-kit-for-international-7300-2004-2006-7-6l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
