When subjected to prolonged low-speed crawling, heavy towing, or high ambient temperatures, the OEM radiator rapidly succumbs to heat soak. The limited coolant volume and restricted surface area prevent efficient thermal transfer, causing coolant temperatures to spike, stressing the cylinder head, and increasing the risk of premature engine failure on the AMC 2.5L and 4.0L engines.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis direct bolt-on upgrade resolves factory cooling limitations utilizing a high-efficiency 3-row tube and fin core constructed from AA5052 aluminum. By expanding the core dimensions to 30.91\" x 10.95\" x 2.00\" and utilizing full TIG-welded aluminum end tanks rather than crimped plastic, this unit drastically improves thermal dissipation. The configuration increases fluid capacity and maximizes the effective cooling surface area, yielding a 35% to 45% increase in cooling efficiency over stock units. The enhanced heat rejection keeps the engine operating within optimal temperature ranges, mitigating the risk of blown head gaskets and effectively eliminating temperature surges during rigorous off-roading. The 1.25-inch inlet and 1.50-inch outlet ensure direct OE fitment with factory hoses.\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;\"\u003e1991-2001 Jeep Cherokee \u0026amp; Comanche\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 150 (2.5L), AMC 242 (4.0L) \/ XJ, MJ\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;\"\u003e125-190 hp \/ 150-225 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\u003e1991-1993 Jeep Cherokee Base Sport Utility 2-Door\u003c\/li\u003e\n  \u003cli\u003e1991-1993 Jeep Cherokee Base Sport Utility 4-Door\u003c\/li\u003e\n  \u003cli\u003e1991-1993 Jeep Comanche Base Standard Cab Pickup 2-Door\u003c\/li\u003e\n  \u003cli\u003e1991-1992 Jeep Cherokee Briarwood Sport Utility 4-Door\u003c\/li\u003e\n  \u003cli\u003e1996, 1998-2001 Jeep Cherokee Classic Sport Utility 4-Door\u003c\/li\u003e\n  \u003cli\u003e1991-1992 Jeep Cherokee Country Sport Utility 2-Door\u003c\/li\u003e\n  \u003cli\u003e1993-1997 Jeep Cherokee Country Sport Utility 4-Door\u003c\/li\u003e\n  \u003cli\u003e1991-1992 Jeep Comanche Eliminator Standard Cab Pickup 2-Door\u003c\/li\u003e\n  \u003cli\u003e1991-1992 Jeep Cherokee Eliminator Standard Cab Pickup 2-Door\u003c\/li\u003e\n  \u003cli\u003e1991-1992 Jeep Cherokee Laredo Sport Utility 4-Door\u003c\/li\u003e\n  \u003cli\u003e1991-1992, 1998-2001 Jeep Cherokee Limited Sport Utility 4-Door\u003c\/li\u003e\n  \u003cli\u003e1991-1992 Jeep Comanche Pioneer Standard Cab Pickup 2-Door\u003c\/li\u003e\n  \u003cli\u003e1994-2001 Jeep Cherokee SE Sport Utility 2-Door\/4-Door\u003c\/li\u003e\n  \u003cli\u003e1994-2001 Jeep Cherokee Sport Sport Utility 2-Door\/4-Door\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Jeep Durability Standard\u003c\/h3\u003e\n\u003cp\u003eBuilt to endure punishing trails and extreme towing environments, this all-aluminum upgrade ensures consistent temperature management, keeping your Jeep reliable whether you are crawling over boulders or navigating remote backcountry terrain.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50115410591992,"sku":"DS-EA33X0EWR","price":149.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/performance-radiator-for-jeep-cherokee-xj-1991-2001-1.webp?v=1785959675","url":"https:\/\/performancechiptuning.com\/fr\/products\/performance-radiator-for-jeep-cherokee-xj-1991-2001","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
