Factory units commonly fail at the crimped header-to-tank seams where composite plastic end tanks become brittle, causing micro-fractures, coolant blow-by, and catastrophic pressure loss. Additionally, particulate and silicate build-up inside narrow factory tube passages reduces heat transfer efficiency, leading to rapid coolant temperature spikes that compromise cylinder head integrity and overheat the transmission circuit on the \u003cstrong\u003eMaxxForce 7\u003c\/strong\u003e platform.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis heavy-duty cross-flow radiator features a dual-row \u003cstrong\u003eT-6061\u003c\/strong\u003e aluminum tube-and-fin core engineered to optimize thermal conductivity and fluid velocity. High-strength reinforced polymer tanks handle extreme hydraulic shock loads without weeping, while precision-stamped header plates ensure structural rigidity against chassis torsion. An integrated high-efficiency transmission oil cooler stabilizes automatic transmission operating temperatures during heavy stop-and-go commercial routes. Factory-dimensioned 2-1\/4 inch inlet and outlet necks and OEM-indexed mounting points permit a direct drop-in installation without shroud or bracket modification.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1x 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: solid font-size: min-width:\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;\"\u003e2007-2009 International 4100\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\u003eMaxxForce 7\u003c\/strong\u003e \/ \u003cstrong\u003eDuraStar\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;\"\u003e200-230 hp \/ 560-620 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\u003e2007-2009 International 4100 Base Medium Duty\u003c\/li\u003e\n  \u003cli\u003e2004-2007 Ford F-650 Commercial (verify core measurements and neck layout prior to ordering)\u003c\/li\u003e\n  \u003cli\u003e2004-2007 Ford F-750 Commercial (verify core measurements and neck layout prior to ordering)\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 4100?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2007-2009 International 4100 equipped with the \u003cstrong\u003eMaxxForce 7\u003c\/strong\u003e diesel engine, using standard OEM mount locations.\u003c\/p\u003e\n\n\u003ch4\u003eDo I need to bleed the cooling system after replacement?\u003c\/h4\u003e\n\u003cp\u003eYes, complete system purging and thermal burping are required to eliminate air pockets around the cylinder heads and EGR coolers prior to returning the truck to service.\u003c\/p\u003e\n\n\u003ch3\u003eThe International Commercial Standard\u003c\/h3\u003e\n\u003cp\u003eBuilt for vocational durability, this radiator assembly provides continuous heat transfer stability under heavy payload cycles, steep grade hauling, and harsh industrial fleet operating conditions.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67610974224632,"sku":"DS-EZWXOTFGV","price":396.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/radiator-for-international-4100-2007-2009-1.jpg?v=1791567400","url":"https:\/\/performancechiptuning.com\/fr\/products\/radiator-for-international-4100-2007-2009","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
