Decades of service expose these vintage systems to severe internal corrosion, calcium buildup, and fin degradation, reducing heat rejection capacity.

Robust, TIG-welded aluminum end tanks eliminate the failure-prone crimped or soldered joints typical of aged stock units. The included precision-formed aluminum fan shroud directs airflow evenly across the entire core surface area, while integrated high-output electric fans generate continuous static pressure regardless of engine RPM. By switching from a parasitic mechanical fan to an electric shroud assembly, the system stabilizes operating temperatures and reduces rotating drag on the engine assembly.\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;\"\u003e1973-1977 Buick Regal\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 231 (3.8L) \/ Buick 350 (5.7L) \/ 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;\"\u003e110-175 hp \/ 175-280 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;\"\u003eCC161, MC161, DPI161, 161, CU161, RAD161, SBR161, 3023837, 3023838, 3023839, 3025223, 3025227, 3025228, 3005745, 52453863, 3005749, 3005823\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1973 Buick Regal (3.8L V6, 5.7L V8)\u003c\/li\u003e\n  \u003cli\u003e1974 Buick Regal (3.8L V6, 5.7L V8)\u003c\/li\u003e\n  \u003cli\u003e1975 Buick Regal (3.8L V6, 5.7L V8)\u003c\/li\u003e\n  \u003cli\u003e1976 Buick Regal (3.8L V6, 5.7L V8)\u003c\/li\u003e\n  \u003cli\u003e1977 Buick Regal (3.8L V6, 5.7L 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 Regal?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 1973-1977 Buick Regal equipped with the \u003cstrong\u003eBuick 231\u003c\/strong\u003e or \u003cstrong\u003eBuick 350\u003c\/strong\u003e engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan the factory transmission cooler lines be connected directly to this radiator?\u003c\/strong\u003e\u003cbr\u003e Yes, the integrated automatic transmission fluid cooler matches standard inverted flare fittings for seamless integration with OEM cooling circuits.\u003c\/p\u003e\n\n\u003ch3\u003eThe Buick Muscle Caliber\u003c\/h3\u003e\n\u003cp\u003eSecond-generation Regal classics demand dependable cooling performance that preserves big displacement power and historic drivability.
