Continuous exposure to under-hood heat bakes the OEM elastomer, causing micro-cracking, neck hardening, and internal ply separation. Under sustained towing or low-speed off-road crawling, elevated cooling system pressure can balloon weakened factory hoses, risking sudden rupture, rapid coolant loss, and severe cylinder head warping on the all-aluminum block.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis kit upgrades the cooling circuit with high-grade, multi-ply reinforced silicone designed to withstand temperature extremes from -65°F to 350°F. Embedded polyester reinforcement layers dramatically increase burst pressure capacity and structural rigidity, preventing vacuum collapse on the suction side and high-pressure expansion on the hot side. The molded, direct-fit routing features a smooth-bore inner wall that promotes laminar coolant flow while resisting oil mist, electrochemical degradation, and standard glycol additives.\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; margin-bottom: 20px;\"\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eFitment\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e2005-2019 Nissan Frontier, Pathfinder, Xterra\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eEngine \/ Chassis\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e\n\u003cstrong\u003eVQ40DE\u003c\/strong\u003e \/ \u003cstrong\u003eD40\u003c\/strong\u003e, \u003cstrong\u003eR51\u003c\/strong\u003e, \u003cstrong\u003eN50\u003c\/strong\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eStock Output\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e261 hp \/ 281 lb-ft\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eReplaces OEM Part #\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\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\u003e2005-2019 Nissan Frontier 4.0L V6 (\u003cstrong\u003eD40\u003c\/strong\u003e Chassis)\u003c\/li\u003e\n  \u003cli\u003e2005-2012 Nissan Pathfinder 4.0L V6 (\u003cstrong\u003eR51\u003c\/strong\u003e Chassis)\u003c\/li\u003e\n  \u003cli\u003e2005-2015 Nissan Xterra 4.0L V6 (\u003cstrong\u003eN50\u003c\/strong\u003e Chassis)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the D40, R51, and N50 Frontier, Pathfinder, and Xterra?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 2005-2019 Nissan Frontier, Pathfinder, and Xterra equipped with the \u003cstrong\u003eVQ40DE\u003c\/strong\u003e engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan factory constant-tension spring clamps be reused with these hoses?\u003c\/strong\u003e\u003cbr\u003e Lined silicone hose clamps or smooth-band worm gear clamps are recommended to prevent cutting into the exterior silicone jacket.\u003c\/p\u003e\n\n\u003ch3\u003eThe Nissan Truck \u0026amp; SUV Standard\u003c\/h3\u003e\n\u003cp\u003eBuilt for the harsh thermal environments of off-road expeditions, heavy hauling, and high-ambient highway towing, this silicone coolant hose kit protects your 4.0L platform from the critical thermal failures that plague aging factory rubber.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50502204162296,"sku":"DS-ED59JXDKR","price":105.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/silicone-hose-kit-for-nissan-frontier-pathfinder-xterra-2005-2019-4-0l-1.jpg?v=1789339511","url":"https:\/\/performancechiptuning.com\/products\/silicone-hose-kit-for-nissan-frontier-pathfinder-xterra-2005-2019-4-0l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
