Over years of thermal cycling, vibration, and coolant degradation, these glass-filled plastic headers become embrittled. Common structural failure points include stress fractures along the tank seams, micro-cracks around the upper inlet neck, and internal transmission oil cooler integrity loss. When paired with the \u003cstrong\u003eLG8 3100\u003c\/strong\u003e V6 engine, any loss of pressure or chronic thermal expansion spikes will accelerate lower intake manifold and cylinder head gasket failures, introducing coolant sludge and localized boiling.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered to exact OEM geometric parameters, this crossflow heat exchanger drops directly into the stock cradle without line modification or bracket fabrication. The core features premium brazed aluminum construction paired with high-density louvered fin arrays designed to maximize ambient airflow dynamics and thermal rejection. High-strength polymer end tanks are reinforced and sealed with vulcanized gaskets to resist cyclic thermal fatigue. Integrated with an internal concentric automatic transmission fluid heat exchanger, this unit directly interchanges with GM numbers \u003cstrong\u003e52401484\u003c\/strong\u003e, \u003cstrong\u003e2343\u003c\/strong\u003e, and \u003cstrong\u003eCU2343\u003c\/strong\u003e, and is 100% factory pressure tested to eliminate out-of-the-box pinhole leaks.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 Replacement Radiator with Integrated Automatic Transmission 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;\"\u003e2000-2005 Buick Century\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;\"\u003eLG8 3.1L V6 \/ W-Body\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 hp \/ 195 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;\"\u003e2343, CU2343, GM3010104, GM3010432, 52401484\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\u003e2000-2005 Buick Century Custom 3.1L V6 Automatic\u003c\/li\u003e\n  \u003cli\u003e2000-2005 Buick Century Limited 3.1L V6 Automatic\u003c\/li\u003e\n  \u003cli\u003e2005 Buick Century Special Edition 3.1L V6 Automatic\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 W-Body Century?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2000-2005 Buick Century equipped with the \u003cstrong\u003eLG8\u003c\/strong\u003e engine. \u003cstrong\u003eDoes not fit 1997-1999 Buick Century models.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch4\u003eDo I need to bleed the air from the cooling system after installation?\u003c\/h4\u003e\n\u003cp\u003eYes, you must bleed trapped air using the brass bleed screws on the thermostat bypass and heater pipe until a continuous stream of coolant emerges, preventing hot spots and inaccurate temperature gauge readings.\u003c\/p\u003e\n\n\u003ch3\u003eThe Buick Reliability Standard\u003c\/h3\u003e\n\u003cp\u003eDaily driven cruisers demand unwavering cooling system reliability, ensuring smooth transmission fluid regulation and durable thermal stability across thousands of highway miles.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67896225530104,"sku":"DS-EUVO0E8DM","price":101.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/radiator-for-buick-century-2000-2005-3-1l-1.jpg?v=1793295109","url":"https:\/\/performancechiptuning.com\/fr\/products\/radiator-for-buick-century-2000-2005-3-1l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
