Over extended thermal cycles, constant pressure fluctuations and high underhood temperatures degrade the plastic polymer matrix, causing micro-fractures around the upper hose inlet neck and failure along the crimped tank-to-core gasket perimeter. Under heavy towing or prolonged hill climbs, elevated cooling system pressures accelerate fatigue, risking catastrophic coolant loss and severe cylinder head warping on the 2UZ-FE V8.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis direct-fit performance radiator replaces brittle plastic with 100% TIG-welded aircraft-grade aluminum end tanks. Eliminating crimped resin seams ensures complete structural integrity under high hydraulic pressures. The optimized brazed multi-louvered fin design expands core surface area, significantly lowering core fluid resistance and accelerating heat transfer rates to prevent heat soak under sustained thermal stress.\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;\"\u003e2000-2006 Toyota Tundra\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;\"\u003e4.7L 2UZ-FE V8 \/ UCK30, UCK40 (XK30\/XK40)\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;\"\u003e245–271 hp \/ 315 lb-ft (Approx)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003ePart Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eOE 16400-0F020 \/ DPI 2321\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2000-2006 Toyota Tundra 4.7L V8 Automatic Transmission\u003c\/li\u003e\n  \u003cli\u003eFits Base, SR5, and Limited trim configurations equipped with the 4.7L 2UZ-FE engine\u003c\/li\u003e\n  \u003cli\u003eDirect-fit replacement for OEM Part Number: 16400-0F020 \/ DPI 2321\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDoes Not Fit:\u003c\/strong\u003e 3.4L V6 (5VZ-FE), 4.0L V6 (1GR-FE), or 2007-later Tundra platforms\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Toyota Durability Caliber\u003c\/h3\u003e\n\u003cp\u003eEngineered for maximum thermal resilience, this all-aluminum unit provides dependable cooling capacity, preventing overheating and maintaining peak powertrain reliability when hauling heavy payload or towing at gross vehicle weight rating.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50416611852536,"sku":"DS-ECFPZMEIY","price":259.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/performance-radiator-for-toyota-tundra-2000-2006-4-7l-automatic-1.jpg?v=1788322815","url":"https:\/\/performancechiptuning.com\/es\/products\/performance-radiator-for-toyota-tundra-2000-2006-4-7l-automatic","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
