Repeated thermal cycling between 195°F and 225°F degrades the plastic, causing brittle neck fractures, micro-fissuring, and catastrophic crimp seam separations. Under sustained high loads, such as towing with the 5.7L HEMI or low-speed crawling with the 3.6L Pentastar, the restrictive OEM single-row core struggles with heat rejection, inducing dangerous coolant pressure and elevated engine temperatures.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis heavy-duty unit eliminates failure points with an all-aluminum construction featuring 100% precision TIG-welded tanks and a vacuum-brazed multi-row tube-and-fin core. By removing failure-prone mechanical crimps and plastic tanks, it withstands elevated operating pressures without leaking. The expanded multi-row core optimizes internal fluid cross-flow and external fin surface area, substantially increasing heat dissipation efficiency. Built as a direct bolt-in unit, it preserves OEM fan shroud alignment, mounting points, and factory hose routing.\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;\"\u003e2011-2021 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;\"\u003e3.6L Pentastar V6, 5.7L HEMI V8 \/ WK2\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;\"\u003e290–360 hp \/ 260–390 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\u003e2011-2021 Jeep Grand Cherokee WK2 3.6L V6\u003c\/li\u003e\n  \u003cli\u003e2011-2021 Jeep Grand Cherokee WK2 5.7L V8\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Jeep Durability Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered for sustained off-road torsional stress, washboard vibration, and heavy trailer pulling, this solid-metal cooling assembly delivers absolute reliability on the trail and highway.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50496536969464,"sku":"DS-ERCO59CEL","price":229.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/aluminum-radiator-for-jeep-grand-cherokee-2011-2021-3-6l-5-7l-1.jpg?v=1789245656","url":"https:\/\/performancechiptuning.com\/fr\/products\/aluminum-radiator-for-jeep-grand-cherokee-2011-2021-3-6l-5-7l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
