Over decades of heat cycling, internal scale accumulation, tube calcification, and solder blooming drastically diminish heat rejection capacity. Under sustained operating loads or low-speed idling, these legacy cores suffer acute heat soak, risking head gasket degradation and detonation in high-displacement V8 powerplants.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis cooling unit features a precision-engineered 3-row aluminum core matched to heavy-gauge, TIG-welded end tanks, eliminating vulnerable epoxy and mechanical gaskets. High-density, multi-louvered cooling fins maximize ambient airflow exposure across the vacuum-brazed fluid tubes to enhance boundary-layer turbulence and heat transfer rates. Aircraft-grade aluminum construction delivers elevated tensile strength and superior corrosion resistance while bolting directly into OEM core support 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;\"\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;\"\u003e1971-1973 Mercury Cougar\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;\"\u003eFord 351 Cleveland (335-Series) \/ Gen 2 Unibody\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;\"\u003e240 hp \/ 350 lb-ft (Approx)\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\u003e1971 Mercury Cougar (Base, XR-7)\u003c\/li\u003e\n  \u003cli\u003e1972 Mercury Cougar (Base, XR-7)\u003c\/li\u003e\n  \u003cli\u003e1973 Mercury Cougar (Base, XR-7)\u003c\/li\u003e\n  \u003cli\u003eEngine Applications: 351 cu in (5.8L) Cleveland V8, 429 cu in (7.0L) V8\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Mercury Muscle Caliber\u003c\/h3\u003e\n\u003cp\u003eBuilt to handle the thermal demands of high-compression vintage Ford V8 drivetrains, this radiator delivers continuous cooling efficiency, preserving power output and powertrain reliability on the street or strip.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50496642679032,"sku":"DS-EU4G9X6XG","price":200.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/aluminum-radiator-for-mercury-cougar-1971-1973-1.jpg?v=1789246773","url":"https:\/\/performancechiptuning.com\/fr\/products\/aluminum-radiator-for-mercury-cougar-1971-1973","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
