Over continuous thermal cycles, the factory polymer tanks embrittle, leading to seam separation and stress fractures at the 1.5-inch inlet and outlet necks. Furthermore, the single-row core suffers from heat soak during heavy towing, low-speed off-road crawling, and high ambient temperatures, risking head gasket failure and elevated automatic transmission fluid temperatures.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eConstructed entirely from aircraft-grade aluminum, this unit features a 100% TIG-welded, vacuum-brazed 3-row crossflow core (23.5 in x 20.875 in) with zero epoxy or crimped plastic seams. The multi-louvered high-density fin architecture expands coolant contact surface area, significantly lowering operating temperatures. It includes an integrated heavy-duty internal transmission oil cooler (26 x 305 mm, 5\/8-18 UNF) engineered to safeguard automatic transmissions under extreme load.\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;\"\u003e1998-2001 Ford Explorer\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;\"\u003e4.0L Cologne V6 \/ UN105 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;\"\u003e160–205 hp \/ 225–240 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;\"\u003eDPI2173 \/ CU2173 \/ RAD2173\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1998-2001 Ford Explorer 4.0L V6 Automatic Transmission\u003c\/li\u003e\n  \u003cli\u003eDoes NOT fit 2002-2005 Ford Explorer (Different core geometry)\u003c\/li\u003e\n  \u003cli\u003eDoes NOT fit 2006-2010 Ford Explorer 4.0L \/ 4.6L models\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Ford Durability Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to handle severe duty cycles, this all-aluminum cooling assembly delivers sustained cooling margins for trail running, heavy payload hauling, and prolonged highway cruising without thermal fade.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50417250468088,"sku":"DS-E7F0A7E6K","price":234.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/performance-radiator-for-ford-explorer-1998-2001-4-0l-automatic-1.jpg?v=1788333125","url":"https:\/\/performancechiptuning.com\/products\/performance-radiator-for-ford-explorer-1998-2001-4-0l-automatic","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
