Under cyclical thermal loading, vibration, and elevated cooling system pressures, these crimp seals degrade, leading to structural fatigue, end-tank fractures, and catastrophic coolant loss. Furthermore, the OEM core volume lacks sufficient heat transfer capacity when towing near the VK56DE platform's maximum gross weight ratings.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis heavy-duty unit utilizes a 100% TIG-welded, all-aluminum construction with a vacuum-brazed 3-row downflow core to eliminate epoxy joints and weak plastic transitions. Operating with 3\/8-inch tube spacing and high-density 14-16 fins per inch, it increases thermal transfer efficiency by 35-45% over OEM specifications. It features a built-in M12x1.0 transmission oil cooler to maintain transmission fluid viscosity under heavy loads and is 100% leak tested.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px;\"\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eFitment\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e2004-2010 Infiniti QX56 (5.6L V8 Automatic)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eEngine \/ Chassis\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eVK56DE \/ JA60 (F-Alpha Platform)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eStock Output\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e315–320 hp \/ 390–393 lb-ft (Approx)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eCore Dimensions\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e26.7\" W x 23.4\" H (Overall: 27.5\" W x 31.1\" H)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eInlet \/ Outlet\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e1-1\/2\" Passenger Side Top \/ 1-1\/2\" Driver Side Bottom\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eOEM \/ Interchange Numbers\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e214607S000, 214609FD0A, 214609FD0B, 214609FD1B, 21460ZC00B, NI3010202, 21460ZC00A, 21460ZQ00A, 10164126, 214607S00A, DPI 2691, CU2691, CC2691, RAD2691\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2004-2010 Infiniti QX56 5.6L V8 GAS (Automatic Transmission)\u003c\/li\u003e\n  \u003cli\u003e\u003cem\u003eNote: Does not fit 2011-later QX56 or QX80 models.\u003c\/em\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Infiniti Heavy-Duty Towing Standard\u003c\/h3\u003e\n\u003cp\u003eBuilt to handle extreme towing duty cycles and severe ambient temperatures, this all-aluminum radiator prevents heat soak, keeps cylinder head temperatures stable, and protects your automatic transmission from thermal breakdown.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50416618897656,"sku":"DS-EMN3DJCZG","price":319.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/performance-radiator-for-infiniti-qx56-2004-2010-5-6l-automatic-1.jpg?v=1788323003","url":"https:\/\/performancechiptuning.com\/es\/products\/performance-radiator-for-infiniti-qx56-2004-2010-5-6l-automatic","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
