Operating in compact engine bays accelerates electrochemical degradation (ECD), causing OEM rubber to harden, develop micro-cracks, and form soft blisters near connection necks. As the factory rubber weakens, it swells under pressure, reducing coolant velocity through the radiator core and increasing the risk of sudden burst failures on high-mileage \u003cstrong\u003e1NZ-FE\u003c\/strong\u003e and \u003cstrong\u003e2NZ-FE\u003c\/strong\u003e powerplants.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered as a direct-fit upgrade, this kit utilizes 3-ply high-grade silicone reinforced with a 4.5 mm wall thickness to deliver superior burst pressure resistance and thermal stability across -65°F to 350°F. The multi-layer reinforced silicone will not dry rot, swell, or crack under repetitive heat soaking. Each hose is pre-formed to match OEM junction geometry on the radiator inlet, outlet, and bypass circuits, while the included stainless steel worm-drive clamps apply balanced radial tension to eliminate coolant weeping at aluminum hose bibs.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e3 Silicone Radiator Hoses (red, 3-ply, 4.5 mm wall)\u003c\/li\u003e\n  \u003cli\u003e6 Stainless Steel Worm-Drive Clamps\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cdiv style=\"overflow-x: auto; margin-bottom: 20px;\"\u003e\n  \u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px; min-width: 300px;\"\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;\"\u003e2004-2007 Scion xB,xA\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;\"\u003e1NZ-FE (1.5L), 2NZ-FE (1.3L) \/ NCP31, NCP61\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;\"\u003e108 hp \/ 105 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\u003c\/div\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2004-2007 Scion xB 1.5L 4-Cylinder (1NZ-FE)\u003c\/li\u003e\n  \u003cli\u003e2004-2007 Scion xA 1.5L 4-Cylinder (1NZ-FE)\u003c\/li\u003e\n  \u003cli\u003e2004-2007 Scion xA 1.3L 4-Cylinder (2NZ-FE)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions \u0026amp; Fitment Warnings\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the NCP31 \/ NCP61 xB,xA?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2004-2007 Scion xB,xA equipped with the \u003cstrong\u003e1NZ-FE\u003c\/strong\u003e 1.5L or \u003cstrong\u003e2NZ-FE\u003c\/strong\u003e 1.3L engine.\u003c\/p\u003e\n\n\u003ch4\u003eDo I need to bleed the cooling system after installing these hoses?\u003c\/h4\u003e\n\u003cp\u003eYes, you must completely drain the system before removal and properly bleed all trapped air pockets upon refill to prevent hot spots in the \u003cstrong\u003e1NZ-FE\u003c\/strong\u003e cylinder head.\u003c\/p\u003e\n\n\u003ch3\u003eThe Scion JDM Standard\u003c\/h3\u003e\n\u003cp\u003eConstructed for enduring JDM platform performance, this silicone coolant kit ensures stable heat dissipation and peace of mind on both daily commuter routes and spirited track runs.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":68059170046200,"sku":"DS-E1JVRI3NA","price":50.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/silicone-radiator-hose-kit-for-scion-xb-xa-2004-2007-1-3l-1-5l-1.jpg?v=1794367625","url":"https:\/\/performancechiptuning.com\/fr\/products\/silicone-radiator-hose-kit-for-scion-xb-xa-2004-2007-1-3l-1-5l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
