Over extended heat cycles, the factory glass-filled nylon end tanks become brittle, developing stress fractures along the tank seams and crimped header plates. Internal thermal resistance escalates as micro-passages clog with spent silicate deposits, while road-facing louvers succumb to rock-peening and salt corrosion. In severe cases, high internal cooling circuit pressures cause total seam separation at the crimped joints, inducing sudden coolant loss that immediately threatens the aluminum cylinder head and deck surfaces of the \u003cstrong\u003eQR25DE\u003c\/strong\u003e and \u003cstrong\u003eVQ35DE\u003c\/strong\u003e engines.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis drop-in replacement radiator restores nominal cooling flow with a brazed aluminum core engineered for low pressure-drop fluid dynamics. Featuring high-density louvered aluminum fins bonded to heavy-gauge flat cooling tubes, it optimizes heat rejection even under stop-and-go load. Reinforced virgin polyamide polymer tanks are secured via continuous, automated mechanically crimped seals with heat-resistant EPDM gaskets to eliminate typical seam weeping. An integrated internal transmission oil cooler matches factory heat exchanger rates, and factory-located mounting tabs eliminate the need for bracket fabrication or hose rerouting.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 Radiator with integrated internal 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;\"\u003e2007-2018 Nissan Altima\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;\"\u003eQR25DE, VQ35DE \/ L32, L33, D32\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;\"\u003e175-270 hp \/ 180-258 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;\"\u003e21460JA00A, 21460ZN50A, 21460ZN50B, CU2988, NI3010210, NI3010241, 13542, 221-3407\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\u003e2007-2018 Nissan Altima 2.5L 4-cylinder (Sedan)\u003c\/li\u003e\n  \u003cli\u003e2008-2013 Nissan Altima 2.5L 4-cylinder (Coupe)\u003c\/li\u003e\n  \u003cli\u003e2007-2018 Nissan Altima 3.5L V6 (Sedan)\u003c\/li\u003e\n  \u003cli\u003e2008-2013 Nissan Altima 3.5L V6 (Coupe)\u003c\/li\u003e\n  \u003cli\u003eDoes NOT fit 2007-2011 Altima Hybrid models\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 L32 and L33 Altima?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2007-2018 Nissan Altima equipped with the \u003cstrong\u003eQR25DE\u003c\/strong\u003e or \u003cstrong\u003eVQ35DE\u003c\/strong\u003e engine. \u003cstrong\u003eNote: This unit does not fit 2007-2011 Altima Hybrid models due to inverter cooling loop discrepancies.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch4\u003eDo I need to bleed the cooling system after replacement?\u003c\/h4\u003e\n\u003cp\u003eYes, thorough cooling system vacuum fill or manual burping is required to purge trapped air pockets and protect against localized hot spots on the aluminum cylinder head.\u003c\/p\u003e\n\n\u003ch3\u003eThe Nissan Reliability Standard\u003c\/h3\u003e\n\u003cp\u003ePreserve your sedan or coupe's powertrain integrity with a cooling module built to withstand daily commuter stress and peak highway thermal loads without pressure degradation.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67896428200184,"sku":"DS-EU7WFPRTA","price":64.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/radiator-for-nissan-altima-2007-2018-2-5l-3-5l-1.jpg?v=1793300075","url":"https:\/\/performancechiptuning.com\/fr\/products\/radiator-for-nissan-altima-2007-2018-2-5l-3-5l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
