Over repeated thermal cycles, high cooling system pressures, and off-road torsional chassis flex on the N280 platform, these crimped seams degrade. The composite inlet and outlet necks become brittle, leading to micro-cracks, sudden tank separation, coolant loss, and severe overheating risks for the aluminum 1GR-FE engine block.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eConstructed entirely from 100% TIG-welded aircraft-grade aluminum, this performance unit replaces fragile plastic tanks with durable, fully welded tanks. The internal core features a high-density louvered fin design and oversized fluid channels, promoting superior convective heat transfer and reducing thermal saturation during sustained low-speed trail ascents or heavy load towing. It includes a built-in transmission oil cooler matching factory line configurations for reliable automatic fluid temperature control.\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;\"\u003e2010-2022 Toyota 4Runner\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;\"\u003e1GR-FE 4.0L V6 \/ N280\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;\"\u003e270 hp \/ 278 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;\"\u003e16400-31710 \/ DPI 13251\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003e2010-2022 Toyota 4Runner 4.0L V6 Automatic:\u003c\/strong\u003e SR5, Trail, TRD Off-Road, TRD Pro, Limited, Nightshade, Venture, SR5 Premium, TRD Off-Road Premium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDirect Replacement OE Numbers:\u003c\/strong\u003e 16400-31710, DPI 13251\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExcluded Fitments:\u003c\/strong\u003e Does not fit 1988-1995 Toyota 4Runner; Does not fit 2010 Toyota 4Runner with 2.7L 4-cylinder engine.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Toyota Trail Durability Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to handle severe trail vibration, sustained grade pulling, and overland weight loads without mechanical fatigue or cooling degradation.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50414493073656,"sku":"DS-E6I1YDDF2","price":244.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/performance-radiator-for-toyota-4runner-2010-2022-4-0l-automatic-2.jpg?v=1788307264","url":"https:\/\/performancechiptuning.com\/products\/performance-radiator-for-toyota-4runner-2010-2022-4-0l-automatic","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
