Over time, intense thermal cycling degrades the plastic construction, leading to hairline cracks and catastrophic coolant loss at the crimped seams. Furthermore, the limited coolant capacity and narrow surface area of the OEM tube-and-fin design struggle to reject heat effectively. This becomes a critical failure point during low-speed off-road articulation, towing, or steep inclines, resulting in rapid heat soak and potential catastrophic engine damage.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis replacement unit abandons the weak plastic construction in favor of aircraft-grade AA5052 aluminum. Featuring a fully TIG-welded, 2-row brazed core, it substantially increases fluid capacity and maximizes heat dissipation. The core measures 36mm (1.42 inches) thick, dramatically expanding the thermal transfer surface area. Upgraded 2mm thick aluminum end tanks completely eliminate the factory crimp joints, while a CNC-machined billet aluminum filler neck ensures a rugged, leak-free seal. This combination delivers a 35% to 45% improvement in overall cooling efficiency, stabilizing operating temperatures during severe duty cycles.\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;\"\u003e1993-1998 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;\"\u003eAMC 4.0L L6 \/ ZJ\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;\"\u003e190 hp \/ 225 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\u003e1993-1998 Jeep Grand Cherokee 4.0L L6 (Automatic Transmission)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Jeep Durability Standard\u003c\/h3\u003e\n\u003cp\u003eBuilt to endure punishing trail conditions and heavy towing demands, this aluminum upgrade ensures your AMC 4.0L maintains optimal operating temperatures, preventing the block warping and head gasket failures notorious in overheated inline-six engines.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50123107205368,"sku":"DS-EYS19M4DR","price":179.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/performance-radiator-for-jeep-grand-cherokee-1993-1998-4-0l-1.webp?v=1786038952","url":"https:\/\/performancechiptuning.com\/es\/products\/performance-radiator-for-jeep-grand-cherokee-1993-1998-4-0l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
