Over time, the factory crimped joints between the core and tanks fatigue, leading to seam weeping, micro-fractures in aging composite side tanks, and internal tube clogging from mineral scale accumulation. This restricts laminar flow across the cooling passages, elevating coolant temperatures and reducing heat dissipation capacity from the \u003cstrong\u003eNavistar DT466\u003c\/strong\u003e \/ \u003cstrong\u003eDT570\u003c\/strong\u003e powertrain, which can quickly lead to blown head gaskets, liner cavitation, and transmission fluid thermal breakdown.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered for high-duty commercial operation, this cross-flow replacement radiator integrates an efficient 2-row core manufactured from premium \u003cstrong\u003eT-6061 aluminum\u003c\/strong\u003e with high-density heat-transfer fins. The dual-row tube configuration optimizes surface area exposure to ensure rapid convective thermal transfer under sustained low-speed, high-load pulling conditions. Reinforced polymer tanks withstand elevated operating pressures, while the integral high-efficiency transmission oil cooler prevents fluid degradation without requiring auxiliary lines. Factory-located 2-1\/4 inch inlet and outlet ports match original hose configurations, providing an exact drop-in replacement that meets OEM flow criteria.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 Aluminum 2-Row Radiator with Integrated Transmission Oil Cooler\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;\"\u003e2002-2005 International 4400\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\u003eDT466\u003c\/strong\u003e \/ \u003cstrong\u003eDuraStar 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;\"\u003e215-300 hp \/ 560-860 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;\"\u003e\n\u003cstrong\u003e2504903C91\u003c\/strong\u003e, \u003cstrong\u003e4C4Z8005DA\u003c\/strong\u003e, \u003cstrong\u003e4C4Z8005FA\u003c\/strong\u003e, \u003cstrong\u003e4C4Z8005LA\u003c\/strong\u003e, \u003cstrong\u003eDNA-OEMRAFL043\u003c\/strong\u003e\n\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\u003e2002-2005 International 4400 Medium-Duty Truck\u003c\/li\u003e\n  \u003cli\u003e2004-2007 Ford F-650 Commercial Truck\u003c\/li\u003e\n  \u003cli\u003e2004-2007 Ford F-750 Commercial Truck\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 DuraStar Platform 4400?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2002-2005 International 4400 equipped with the \u003cstrong\u003eDT466\u003c\/strong\u003e or \u003cstrong\u003eDT570\u003c\/strong\u003e engine, provided core dimensions match 20-1\/2 in H x 25-5\/8 in W x 2-1\/4 in D.\u003c\/p\u003e\n\n\u003ch4\u003eDo I need to bleed the system after installation?\u003c\/h4\u003e\n\u003cp\u003eYes, fully drain the cooling circuit, transfer all OEM sensors and brackets, refill with specified heavy-duty coolant, and completely bleed all air pockets prior to placing the vehicle into severe hauling service.\u003c\/p\u003e\n\n\u003ch3\u003eThe International Hauling Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to handle severe GCWR commercial hauling, rigorous urban stop-and-go duty cycles, and prolonged idle times, this radiator is designed to ensure optimal thermal regulation to protect your commercial fleet powertrain investments.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67610973700344,"sku":"DS-E81SE40YR","price":396.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/radiator-for-international-4400-2002-2005-1.jpg?v=1791567354","url":"https:\/\/performancechiptuning.com\/de\/products\/radiator-for-international-4400-2002-2005","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
