Over years of thermal cycling, engine vibrations, and pressure spikes, these polymer tanks embrittle, crack at the inlet\/outlet necks, and develop seam leaks. Furthermore, stock single-row core depths limit heat dissipation during low-speed crawling or heavy bed loads, leading to rapid heat soak and elevated transmission fluid temperatures via integrated cooler lines.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis drop-in performance unit is constructed from premium 100% TIG-welded aircraft-grade aluminum, eliminating mechanical crimps and gasket failure points completely. Featuring a high-efficiency core with dense louvered fins and wide cooling tubes, it significantly expands surface area to optimize convective heat transfer. The internal fluid paths are engineered for balanced flow distribution, lowering cylinder head operating temperatures and resisting fatigue from extreme operating pressures.\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;\"\u003e5VZ-FE (3.4L) \u0026amp; 1GR-FE (4.0L) \/ 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;\"\u003e190–236 hp \/ 220–266 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 16410-07090 \/ DPI 2320\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2000-2004 Toyota Tundra 3.4L V6 (5VZ-FE) - Base, SR5 (Automatic \u0026amp; Manual)\u003c\/li\u003e\n  \u003cli\u003e2005-2006 Toyota Tundra 4.0L V6 (1GR-FE) - Base, SR5 (Automatic \u0026amp; Manual)\u003c\/li\u003e\n  \u003cli\u003e\u003cem\u003eNote: Does not fit 4.7L V8 (2UZ-FE) models or 2007+ (Gen 2) Tundra.\u003c\/em\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Toyota Truck Caliber\u003c\/h3\u003e\n\u003cp\u003eBuilt for first-generation Tundra platforms operating under rigorous payload and trail demands, this all-aluminum cooling assembly delivers long-term structural integrity and steady thermal regulation without cracking under stress.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50414496186616,"sku":"DS-ERMTN4NIT","price":249.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/performance-radiator-for-toyota-tundra-2000-2006-3-4l-4-0l-1.jpg?v=1788307625","url":"https:\/\/performancechiptuning.com\/products\/performance-radiator-for-toyota-tundra-2000-2006-3-4l-4-0l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
