Over repeated thermal cycles, pressurized coolant exposure and engine vibration degrade the composite plastic, causing embrittlement, micro-cracking, and seal blowouts along the crimp seams. Furthermore, restricted fluid capacity in the OEM core leads to rapid heat soak during low-speed rock crawling or sustained uphill towing, pushing 3.7L, 4.7L, and high-output 6.1L SRT engines toward thermal limits.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eConstructed from aircraft-grade AA5052 aluminum, this radiator features 100% TIG-welded end tanks to eliminate mechanical crimps and plastic failure points. The 2-row, 1.6-inch thick core optimizes fluid capacity and heat transfer surface area via high-efficiency louvered fins. Built specifically for automatic configurations, it includes internal transmission cooling provisions, a precision brass petcock drain, and OE mounting points for seamless installation.\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;\"\u003e2005-2010 Jeep Grand Cherokee\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 PowerTech, 4.7L PowerTech, 6.1L HEMI \/ WK Chassis\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;\"\u003e210–420 hp \/ 235–420 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;\"\u003eDPI 2839, CU 2839, 8012839, 3292, 2999, 55116849AC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2005-2010 Jeep Grand Cherokee (WK) 3.7L V6 Automatic\u003c\/li\u003e\n  \u003cli\u003e2005-2009 Jeep Grand Cherokee (WK) 4.7L V8 Automatic\u003c\/li\u003e\n  \u003cli\u003e2006-2010 Jeep Grand Cherokee (WK) SRT8 6.1L HEMI V8 Automatic\u003c\/li\u003e\n  \u003cli\u003e2007-2010 Jeep Grand Cherokee (WK) 3.0L V6 Turbo Diesel Automatic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitment Note:\u003c\/strong\u003e Does NOT fit 5.7L Hemi models (different radiator core).\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChassis Note:\u003c\/strong\u003e Does NOT fit 1999-2004 WJ models.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Jeep Durability Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to withstand chassis flex during extreme off-camber articulation and high-strain towing, this reinforced all-aluminum unit provides sustained thermal control and structural integrity across demanding trail and highway conditions.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50417247289592,"sku":"DS-E0ST37Q3Q","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-grand-cherokee-2005-2010-3-7l-4-7l-6-1l-automatic-1.jpg?v=1788333037","url":"https:\/\/performancechiptuning.com\/fr\/products\/performance-radiator-for-jeep-grand-cherokee-2005-2010-3-7l-4-7l-6-1l-automatic","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
