Original copper-brass units and aging replacement radiators suffer from internal tube scaling, core oxidation, and fatigued solder joints. Decades of thermal cycling weaken these seams, degrading coolant flow velocity and heat rejection. This breakdown leads to creeping coolant temperatures during hot idle, vapor lock vulnerability, and severe heat soak under load.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis high-efficiency replacement features an all-aluminum core constructed with furnace-brazed tubes and high-density louvered fins, paired with hand TIG-welded structural aluminum end tanks. The 3-row configuration significantly increases fluid volume and active surface area over stock configurations. By eliminating brittle plastic tanks and failure-prone gaskets, this unit resists chassis torsion and internal cooling system pressure spikes without cracking or weeping.\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;\"\u003e1984-1988 Jeep Grand Wagoneer\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;\"\u003eAMC 360 V8 (5.9L) \/ SJ Platform\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;\"\u003e144 hp \/ 280 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\u003e1984 Jeep Grand Wagoneer 5.9L V8\u003c\/li\u003e\n  \u003cli\u003e1985 Jeep Grand Wagoneer 5.9L V8\u003c\/li\u003e\n  \u003cli\u003e1986 Jeep Grand Wagoneer 5.9L V8\u003c\/li\u003e\n  \u003cli\u003e1987 Jeep Grand Wagoneer 5.9L V8\u003c\/li\u003e\n  \u003cli\u003e1988 Jeep Grand Wagoneer 5.9L V8\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Jeep Durability Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered specifically for the structural demands of the full-size SJ chassis, this cooling assembly maintains stable coolant operating temperatures whether pulling heavy cargo up steep highway grades or navigating technical trails at low speeds.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50496549814520,"sku":"DS-E157P3ZZT","price":227.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/aluminum-radiator-for-jeep-grand-wagoneer-1984-1988-5-9l-1.jpg?v=1789246244","url":"https:\/\/performancechiptuning.com\/es\/products\/aluminum-radiator-for-jeep-grand-wagoneer-1984-1988-5-9l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
