Over decades, internal core calcification and solder joint fatigue drastically compromise thermal transfer. Furthermore, massive displacement powerplants like the \u003cstrong\u003eCadillac 472 (7.7L)\u003c\/strong\u003e produce severe thermal loads that easily exceed the capacity of degraded OEM radiators, leading to warped cylinder heads, blown head gaskets, and chronic vapor locking in traffic.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis drop-in cooling upgrade utilizes a heavy-duty, all-aluminum tube-and-fin core engineered for superior heat rejection. Aircraft-grade aluminum end tanks are 100% TIG-welded to the core, eliminating leak-prone gaskets and structural failure under operating pressure. An integrated, form-fitted aluminum shroud forces focused airflow across the entire core surface via an included high-CFM electric fan assembly, eliminating low-speed cooling deficits inherent to mechanical fan clutches.\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;\"\u003e1971-1982 Cadillac Deville\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;\"\u003e4.1L HT4100 \/ 5.7L 350 \/ 7.7L 472 \/ GM C-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;\"\u003e125 - 345 hp \/ 190 - 430 lb-ft (engine dependent)\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, DPI161, 3023837, 3025223, 52453863\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1971-1976 Cadillac Coupe de Ville \/ Sedan de Ville (7.7L 472 ci V8)\u003c\/li\u003e\n  \u003cli\u003e1977-1982 Cadillac Coupe de Ville \/ Sedan de Ville (5.7L 350 ci V8)\u003c\/li\u003e\n  \u003cli\u003e1980-1982 Cadillac Coupe de Ville \/ Sedan de Ville (4.1L V6 \/ HT4100 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 C-body Deville?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct bolt-in fit for 1971-1982 Cadillac Deville models equipped with factory 4.1L, 5.7L, or 7.7L engines.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this unit feature an integrated transmission oil cooler?\u003c\/strong\u003e\u003cbr\u003e Yes, the lower tank includes standard internal heat-exchanger fittings to plumb and cool GM Turbo-Hydramatic automatic transmissions.\u003c\/p\u003e\n\n\u003ch3\u003eThe Cadillac Classic Caliber\u003c\/h3\u003e\n\u003cp\u003ePreserving the effortless cruising characteristics of vintage Cadillac platforms demands bulletproof cooling reliability.
