Over time, OEM crimped tank seams and aged copper-brass or composite cores degrade under high-pressure thermal cycles and severe chassis articulation. Under sustained low-speed crawling or heavy towing, the 6.5L turbodiesel generates extreme thermal loads that outpace the heat rejection capabilities of aged stock cores, causing frequent heat soak, elevated transmission temperatures, and chronic coolant weeping.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis heavy-duty 4-row cooling assembly is constructed entirely from aircraft-grade aluminum, utilizing fully brazed flat-tube passages and high-density louvered fins paired with TIG-welded cast-aluminum end tanks. By eliminating failure-prone rubber gaskets and crimp tabs, structural rigidity is significantly increased to resist chassis flex. The high-capacity 4-row design expands fluid capacity and maximizes surface heat dissipation, maintaining laminar coolant flow and rapid thermal transfer under demanding conditions while utilizing factory mounting provisions.\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;\"\u003e2002-2004 Hummer H1\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;\"\u003e6.5L Turbo Diesel (L65 \/ GEP Optimizer) \/ H1 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;\"\u003e205 hp \/ 440 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\u003e2002 Hummer H1 6.5L Turbo Diesel V8 (Base, Open Top, Wagon)\u003c\/li\u003e\n  \u003cli\u003e2003 Hummer H1 6.5L Turbo Diesel V8 (Base, Open Top, Wagon)\u003c\/li\u003e\n  \u003cli\u003e2004 Hummer H1 6.5L \/ 6.6L Turbo Diesel V8 (Base, Open Top, Wagon)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Hummer Durability Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to handle severe trail washboards, sustained continuous grade pulls, and heavy vehicle recovery operations, this all-aluminum core provides reliable heat rejection and structural durability under maximum gross vehicle weight.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50496547094776,"sku":"DS-EF8IIBGMP","price":403.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/aluminum-radiator-for-hummer-h1-2002-2004-6-5l-6-6l-1.jpg?v=1789245851","url":"https:\/\/performancechiptuning.com\/es\/products\/aluminum-radiator-for-hummer-h1-2002-2004-6-5l-6-6l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
