Repeated thermal cycling, high system pressures, and continuous engine bay heat soak degrade the polymer tanks, causing stress fractures at the inlet neck and separation along the crimp seam. Under high-load conditions such as hill climbs or trail crawling, the thin factory core lacks the fluid volume and surface area required to prevent rapid coolant temperature spikes, leading to transmission overheating and engine degradation.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis drop-in cooling upgrade features 100% TIG-welded AA5052 aircraft-grade aluminum construction, eliminating failure-prone plastic tanks and epoxy seals. Engineered with a high-efficiency 2-row core measuring 1.6 inches in thickness, it substantially increases fluid capacity and thermal dissipation surface area over OEM units. Precision furnace-brazed cooling tubes maximize coolant contact, while louvered multi-louver fins optimize front-to-back airflow across the core. Features a built-in automatic transmission cooler and an OEM-spec brass petcock drain.\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;\"\u003e2006-2010 Jeep Commander\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;\"\u003e3.7L V6 (EKG) \/ 4.7L V8 (PowerTech) \/ XK 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;\"\u003e210-305 hp \/ 235-334 lb-ft (Approx)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eCore Dimensions\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e20.0\" H x 23.2\" W x 1.6\" T (2-Row AA5052 Aluminum)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eInlet \/ Outlet\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e1.50\" Inlet \/ 1.25\" Outlet\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003ePart Numbers \/ Interchange\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e55116849AC, DPI 2839, 8012839, 3292, 2999\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2006-2010 Jeep Commander 3.7L V6 Automatic\u003c\/li\u003e\n  \u003cli\u003e2006-2009 Jeep Commander 4.7L V8 Automatic\u003c\/li\u003e\n  \u003cli\u003eDoes not fit 6.1L SRT8 models\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Jeep Trail-Ready Standard\u003c\/h3\u003e\n\u003cp\u003eBuilt to withstand torsional chassis flex and punishing off-camber trail stress, this heavy-duty unit ensures consistent heat rejection whether hauling payloads up mountain grades or idling in low-range 4WD.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50417248502008,"sku":"DS-EQALSMAVW","price":229.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/performance-radiator-for-jeep-commander-2006-2010-3-7l-4-7l-automatic-1.jpg?v=1788333068","url":"https:\/\/performancechiptuning.com\/fr\/products\/performance-radiator-for-jeep-commander-2006-2010-3-7l-4-7l-automatic","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
