Over repeated thermal cycles, the composite tanks embrittle and fracture along the seam seals and inlet necks. On supercharged L67 applications, elevated coolant temperatures and cylinder head heat soak rapidly exceed the thermal dissipation capacity of the stock core, leading to elevated intake charge temperatures, pre-ignition knock, and transmission fluid overheating via the undersized internal cooler.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis drop-in unit is built from aircraft-grade AA5052 aluminum, featuring precision TIG-welded tanks and a 3-row racing tube crossflow core measuring 14-7\/8\" H x 30-3\/7\" W. The increased tube surface area dramatically accelerates heat transfer while reducing coolant flow restriction. Each unit includes an internal 5\/8-18UNF transmission oil cooler to safeguard the 4T65E transaxle, 1-1\/3\" inlet and 1-5\/16\" outlet ports, a billet-style radiator cap, and 100% leak testing from the factory.\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 Regal (3.8L Automatic)\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;\"\u003e3800 Series II (L36 \/ L67 Supercharged) \/ 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;\"\u003e195-240 hp \/ 225-280 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\u003eOverall Dimensions\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e36 in x 18-5\/8 in x 6-1\/3 in\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eInlet \/ Outlet Size\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 style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eTrans Cooler Thread\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e5\/8-18UNF Integrated Cooler\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;\"\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 Regal LS \/ GS 3.8L V6 (Naturally Aspirated \u0026amp; Supercharged)\u003c\/li\u003e\n  \u003cli\u003e1998 Buick Regal LS \/ GS 3.8L V6 (Naturally Aspirated \u0026amp; Supercharged)\u003c\/li\u003e\n  \u003cli\u003e1999 Buick Regal LS \/ GS 3.8L V6 (Naturally Aspirated \u0026amp; Supercharged)\u003c\/li\u003e\n  \u003cli\u003e\u003cem\u003eNote: Fits 3.8L Regal automatic models only; does not fit 3.1L Century platforms.\u003c\/em\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Buick Performance Caliber\u003c\/h3\u003e\n\u003cp\u003eEngineered to withstand the demanding thermal cycle of forced induction and hard street driving, this radiator ensures stable operating temperatures and long-term reliability for high-torque GM W-Body platforms.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50426239254776,"sku":"DS-EMACO9EUK","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-regal-1997-1999-3-8l-1.jpg?v=1788397488","url":"https:\/\/performancechiptuning.com\/products\/performance-radiator-for-buick-regal-1997-1999-3-8l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
