Over time, internal barrier rupture causes transmission fluid and engine coolant to intermix—a catastrophic failure mode commonly known as \"SMOD\" (Strawberry Milkshake of Death) that destroys the automatic transmission. Furthermore, the OEM plastic tanks become brittle from constant pressure and heat cycling, resulting in hairline fractures, coolant loss, and severe engine overheating during towing or off-road operation.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eConstructed entirely from aircraft-grade aluminum with 100% TIG-welded seams, this performance radiator eliminates crimped joints and brittle plastic failure points. The furnace-brazed core features high-density micro-tubes and multi-louvered fins to maximize thermal transfer surface area, lowering coolant temperatures during steep grade ascents and heavy towing. Engineered with an integrated, pressure-tested automatic transmission cooler assembly, it guarantees fluid isolation while matching OE mounting locations, fan shroud brackets, and inlet\/outlet plumbing.\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;\"\u003e2005-2012 Nissan Pathfinder\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 VQ40DE \/ 5.6L VK56DE | R51 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;\"\u003e266 hp (VQ40) \/ 310 hp (VK56) | 288-388 lb-ft\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;\"\u003eOE 21460-9CA0E \/ DPI 2807\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2005-2012 Nissan Pathfinder 4.0L V6 (VQ40DE) Automatic Transmission\u003c\/li\u003e\n  \u003cli\u003e2008-2012 Nissan Pathfinder 5.6L V8 (VK56DE) Automatic Transmission\u003c\/li\u003e\n  \u003cli\u003eNote: Does not fit 2013-later (R52) Pathfinder models.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Nissan Durability Standard\u003c\/h3\u003e\n\u003cp\u003eBuilt to handle the rigorous demands of sustained high-torque towing and aggressive overland excursions, this performance cooling unit ensures uncompromising drivetrain reliability and thermal stability across all driving conditions.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50414496088312,"sku":"DS-E4VA2K7KC","price":239.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/performance-radiator-for-nissan-pathfinder-2005-2012-4-0l-5-6l-automatic-1.jpg?v=1788307563","url":"https:\/\/performancechiptuning.com\/products\/performance-radiator-for-nissan-pathfinder-2005-2012-4-0l-5-6l-automatic","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
