Over repeated thermal cycles, engine vibration and heat soak degrade the polymer structure, resulting in stress cracking along the inlet neck and catastrophic seam separation. Furthermore, restricted fluid volume limits heat dissipation during extended idle or severe ambient conditions, accelerating coolant breakdown.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eConstructed entirely from aircraft-grade AA5052 aluminum, this performance unit eliminates leak-prone mechanical crimps and plastic components with 100% precision TIG-welded seams. The oversized 3-row tube core dramatically expands fluid capacity and surface cooling area compared to OEM units. Designed with an integrated 5\/8-18UNF automatic transmission oil cooler, this crossflow assembly maintains optimal operational temperatures under continuous load while offering complete drop-in fitment.\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;\"\u003e1997-1999 Buick Century\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;\"\u003e3.1L L82 V6 \/ GM W-Body\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;\"\u003e160 hp \/ 185 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;\"\u003e14 7\/8 in H x 30 3\/7 in W (3-Row Crossflow)\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\/3 in Inlet \/ 1-5\/16 in Outlet\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eTOC Thread\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e5\/8-18UNF Internal Transmission Cooler\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003ePart Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eN\/A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1997 Buick Century Custom 3.1L V6 Automatic (W-Body)\u003c\/li\u003e\n  \u003cli\u003e1997 Buick Century Limited 3.1L V6 Automatic (W-Body)\u003c\/li\u003e\n  \u003cli\u003e1998 Buick Century Custom 3.1L V6 Automatic (W-Body)\u003c\/li\u003e\n  \u003cli\u003e1998 Buick Century Limited 3.1L V6 Automatic (W-Body)\u003c\/li\u003e\n  \u003cli\u003e1999 Buick Century Custom 3.1L V6 Automatic (W-Body)\u003c\/li\u003e\n  \u003cli\u003e1999 Buick Century Limited 3.1L V6 Automatic (W-Body)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Buick Reliability Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to restore long-distance dependability to the GM W-body platform, this heavy-duty cooling assembly protects internal powertrain components by preventing high-temp fluid degradation and thermal breakdown across demanding daily commute cycles.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50426247839992,"sku":"DS-EBXIQUK2C","price":219.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/performance-radiator-for-buick-century-1997-1999-3-1l-1.jpg?v=1788397516","url":"https:\/\/performancechiptuning.com\/fr\/products\/performance-radiator-for-buick-century-1997-1999-3-1l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
