Extended severe-duty thermal cycling, high system pressure spikes, and chassis torsional vibration stress these crimp joints over time. This leads to dry rot, tank seam separation, hairline stress fractures, and internal tube clogging from silicate precipitation. Once coolant weeping initiates, drops in system pressure cause premature boiling, elevated cylinder head temperatures, and ECM torque derate on the \u003cstrong\u003eMaxxForce 13\u003c\/strong\u003e or \u003cstrong\u003eCummins ISX15\u003c\/strong\u003e platform.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered for high-mileage regional and line-haul dependability, this heavy-duty unit features 100% brazed all-aluminum construction with robotic TIG-welded tanks that eliminate failure-prone crimped gaskets. A rugged 2-row, 48 mm core (35.24 x 40.55 in) delivers maximized surface area and optimized fin density, yielding superior conductive heat transfer and turbulent internal coolant velocity. Featuring 2.52-inch inlet and outlet necks, the unit withstands extreme pressure oscillations and heavy road shock while dropping straight into the factory isolation mounts without chassis modifications.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 All-Aluminum Heavy-Duty Radiator\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;\"\u003e2010-2015 International ProStar,8600\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 11\/13, Cummins ISX15\u003c\/strong\u003e \/ \u003cstrong\u003eClass 8 Conventional\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;\"\u003e450 hp \/ 1,650 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\u003e2604295C92\u003c\/strong\u003e, \u003cstrong\u003e2604295C93\u003c\/strong\u003e, \u003cstrong\u003e2604295C94\u003c\/strong\u003e, \u003cstrong\u003e2513233C1\u003c\/strong\u003e, \u003cstrong\u003e20013547\u003c\/strong\u003e, \u003cstrong\u003e1040305\u003c\/strong\u003e, \u003cstrong\u003e382Y1-US\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\u003e2010-2015 International ProStar\u003c\/li\u003e\n  \u003cli\u003e2010-2015 International 8600 TranStar\u003c\/li\u003e\n  \u003cli\u003e2010-2011 International 8500 TranStar\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 Class 8 Conventional ProStar,8600?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2010-2015 International ProStar,8600 equipped with the \u003cstrong\u003eMaxxForce 11\/13\u003c\/strong\u003e or \u003cstrong\u003eCummins ISX15\u003c\/strong\u003e engine.\u003c\/p\u003e\n\n\u003ch4\u003eDo I need to bleed the system after radiator installation?\u003c\/h4\u003e\n\u003cp\u003eYes, you must transfer original fittings and sensors, refill with heavy-duty extended life coolant (ELC), and thoroughly bleed trapped air to prevent hot spots and cavitation.\u003c\/p\u003e\n\n\u003ch3\u003eThe International Heavy-Haul Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to handle severe GCWR commercial hauling demands, this all-welded heat exchanger is designed to ensure sustained heat rejection under maximum grade climbs and stop-and-go terminal transit.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67610987299064,"sku":"DS-EVQ3NHWGI","price":620.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/radiator-for-international-prostar-8600-2010-2015-1.jpg?v=1791568100","url":"https:\/\/performancechiptuning.com\/es\/products\/radiator-for-international-prostar-8600-2010-2015","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
