The end tanks are fabricated from heavy-gauge aluminum and 100% TIG-welded to the core, eliminating mechanical crimp seals and problematic solder joints entirely. Increased internal cross-sectional area lowers coolant flow resistance, allowing high-volume water pump circulation while optimizing thermal transfer rates without modifying factory shroud mounting points.\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; margin-bottom: 20px;\"\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;\"\u003e1979-1981 Oldsmobile Cutlass\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;\"\u003eBuick 3.8L (231 ci) \/ Olds 4.3L (260 ci) \/ GM A-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;\"\u003e105-115 hp \/ 190-205 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;\"\u003eCC571, AE571, EC571, MC571, DPI571, CU571\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1979 Oldsmobile Cutlass (Base, Supreme, Calais, Brougham) 3.8L V6 \/ 4.3L V8\u003c\/li\u003e\n  \u003cli\u003e1980 Oldsmobile Cutlass (Base, Supreme, Calais, Cruiser, Brougham) 3.8L V6 \/ 4.3L V8\u003c\/li\u003e\n  \u003cli\u003e1981 Oldsmobile Cutlass (Base, Supreme, Calais, Cruiser, Brougham) 3.8L V6 \/ 4.3L V8\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the GM A-body Cutlass?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 1979-1981 Oldsmobile Cutlass equipped with the \u003cstrong\u003eBuick 3.8L V6\u003c\/strong\u003e or \u003cstrong\u003eOlds 260 4.3L V8\u003c\/strong\u003e engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this unit feature an integrated transmission cooler?\u003c\/strong\u003e\u003cbr\u003e Yes, it includes internal transmission cooler lines compatible with standard GM inverted-flare fittings for automatic transmissions.\u003c\/p\u003e\n\n\u003ch3\u003eThe Oldsmobile Classic Muscle Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to preserve classic American rear-wheel-drive platforms, this performance cooling upgrade delivers reliable thermal management that protects vintage powertrain components on hot asphalt and heavy acceleration pulls.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50593929167096,"sku":"DS-EYXME3T75","price":179.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/performance-radiator-for-oldsmobile-cutlass-1979-1981-3-8l-4-3l-1.jpg?v=1790053295","url":"https:\/\/performancechiptuning.com\/fr\/products\/performance-radiator-for-oldsmobile-cutlass-1979-1981-3-8l-4-3l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
