Decades of thermal cycling, internal corrosion, and mineral sediment buildup inevitably lead to choked core tubes, weakened seams, and catastrophic coolant leaks.

The precision TIG-welded aluminum end tanks eliminate failure-prone solder joints and pressed seals entirely. Engineered with an optimized louvered fin design and wide fluid tubes, the core facilitates rapid heat conduction away from engine coolant while preserving unobstructed airflow. Featuring a 1.50\" upper inlet and 1.77\" lower outlet, it sustains uniform coolant velocity and superior heat dissipation without creating excessive hydraulic resistance.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 x 3-Row Aluminum Performance Radiator\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cdiv style=\"overflow-x: auto; margin-bottom: 20px;\"\u003e\n  \u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px; min-width: 300px;\"\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;\"\u003e1955-1957 Chevrolet Bel Air, 150, 210\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;\"\u003eTurbo-Fire 265 \/ 283 V8 (Small Block Chevy) \/ Tri-Five Platform\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;\"\u003e162–283 hp \/ 257–290 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;\"\u003eN\/A\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n\u003c\/div\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1955-1957 Chevrolet Bel Air 4.3L V8\u003c\/li\u003e\n  \u003cli\u003e1955-1957 Chevrolet Bel Air 4.6L V8\u003c\/li\u003e\n  \u003cli\u003e1955-1957 Chevrolet 150 4.3L V8\u003c\/li\u003e\n  \u003cli\u003e1955-1957 Chevrolet 150 4.6L V8\u003c\/li\u003e\n  \u003cli\u003e1955-1957 Chevrolet 210 4.3L V8\u003c\/li\u003e\n  \u003cli\u003e1955-1957 Chevrolet 210 4.6L V8\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions \u0026amp; Fitment Warnings\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the Tri-Five Bel Air, 150, 210?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 1955-1957 Chevrolet Bel Air, 150, and 210 equipped with 4.3L or 4.6L Small Block V8 engines. \u003cstrong\u003eThis radiator is engineered strictly for V8 applications and will not fit Inline-6 (I6) engine configurations.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch4\u003eWhat steps should be completed during installation?\u003c\/h4\u003e\n\u003cp\u003eAlways verify hose routing, connection diameters, and transmission-cooler provisions prior to installation, thoroughly flush the engine block, and purge air pockets after refilling.\u003c\/p\u003e\n\n\u003ch3\u003eThe Chevrolet Caliber\u003c\/h3\u003e\n\u003cp\u003eEngineered for high-torque American V8 iron, this aluminum heat exchanger provides the thermal margin needed to protect your classic small-block investment under hard acceleration, prolonged cruising, and high ambient temperatures.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":68057479053560,"sku":"DS-EAQ4LNMQU","price":156.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/performance-radiator-for-chevrolet-bel-air-150-210-1955-1957-4-3l-4-6l-1.jpg?v=1794344871","url":"https:\/\/performancechiptuning.com\/fr\/products\/performance-radiator-for-chevrolet-bel-air-150-210-1955-1957-4-3l-4-6l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
