Over time, factory hoses develop micro-cracks, soften, and become prone to ballooning under standard 13-16 psi cooling system pressure. In off-camber trail environments or continuous high-load towing, localized boiling and pressure spikes easily rupture compromised stock rubber, resulting in rapid coolant loss and catastrophic cylinder head warping on the \u003cstrong\u003e5VZ-FE\u003c\/strong\u003e power plant.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis cooling upgrade utilizes high-grade, multi-ply reinforced silicone engineered to withstand continuous operating temperatures ranging from -65°F to 350°F (-54°C to 177°C) and burst pressures far exceeding factory thresholds. Featuring an ultra-smooth internal bore, it reduces fluid shear and maintains laminar coolant flow into the thermostat housing and heater core. The molded multi-layer polyester reinforcement mesh resists collapse under high suction pressure, resists vacuum flattening at high RPM, and prevents petroleum\/oil permeation, ensuring rock-solid cooling performance across harsh overland conditions.\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;\"\u003e1996-2002 Toyota 4Runner\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\u003e5VZ-FE\u003c\/strong\u003e \/ \u003cstrong\u003eN180\u003c\/strong\u003e (VZN180 \/ VZN185)\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;\"\u003e183 hp \/ 217 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\u003e1996-2002 Toyota 4Runner Base 3.4L V6 (5VZ-FE)\u003c\/li\u003e\n  \u003cli\u003e1996-2002 Toyota 4Runner SR5 3.4L V6 (5VZ-FE)\u003c\/li\u003e\n  \u003cli\u003e1996-2002 Toyota 4Runner Limited 3.4L V6 (5VZ-FE)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the N180 4Runner?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 1996-2002 Toyota 4Runner equipped with the \u003cstrong\u003e5VZ-FE\u003c\/strong\u003e 3.4L V6 engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I reuse the OEM spring-style hose clamps with these silicone hoses?\u003c\/strong\u003e\u003cbr\u003e We recommend using lined worm-gear or constant-tension T-bolt clamps to avoid cutting into the silicone outer jacket under expansion.\u003c\/p\u003e\n\n\u003ch3\u003eThe Toyota Durability Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered for high-mileage overland rigs, rock crawlers, and tow vehicles, this silicone replacement kit eliminates the most common roadside cooling failure points so your rig stays reliable on remote trails.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50502200983800,"sku":"DS-EI7M59G88","price":137.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/silicone-hose-kit-for-toyota-4runner-1996-2002-3-4l-1.jpg?v=1789339413","url":"https:\/\/performancechiptuning.com\/products\/silicone-hose-kit-for-toyota-4runner-1996-2002-3-4l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
