Over years of thermal cycling, the factory PA66 plastic end tanks become brittle, developing microscopic stress fractures near the crimped header plate seam and upper radiator hose inlet. Furthermore, corrosion, road debris, and internal scale buildup clog the delicate single-pass channels of the stock \u003cstrong\u003e1NZ-FE\u003c\/strong\u003e heat exchanger. Once thermal dissipation degrades, localized hot spots accelerate head gasket wear and cause coolant blow-by during prolonged idle or high ambient load.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis replacement heat exchanger features a brazed aluminum core engineered with high-density louvered fin architecture to maximize heat transfer efficiency and surface-area contact. Reinforced heavy-duty composite end tanks are secured with multi-point crimped perimeter joints and high-durometer seals to resist high-pressure spikes and thermal shock. Engineered to exact OEM dimensional tolerances, it includes factory-matched port locations, mounting pins, and transmission cooler provisions for direct drop-in integration without clearance modifications.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 Radiator\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;\"\u003e2004-2006 Scion xA,xB\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 \/ XP20 (xA), XP30 (xB)\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;\"\u003e1640021070, 1640021071, 1640021080, 1640021081, CU2305\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\u003e2004-2006 Scion xA 1.5L 4-cylinder\u003c\/li\u003e\n  \u003cli\u003e2004-2006 Scion xB 1.5L 4-cylinder\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 XP20 \/ XP30 xA,xB?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2004-2006 Scion xA,xB equipped with the \u003cstrong\u003e1NZ-FE\u003c\/strong\u003e engine.\u003c\/p\u003e\n\n\u003ch4\u003eDo I need to bleed the system after installation?\u003c\/h4\u003e\n\u003cp\u003eYes, refilling with factory-specified coolant and fully burping the cooling system of trapped air pockets is mandatory to prevent thermal airlocks and irregular thermostat cycling.\u003c\/p\u003e\n\n\u003ch3\u003eThe Scion Reliability Caliber\u003c\/h3\u003e\n\u003cp\u003eEngineered for high-mileage urban dependability, this radiator ensures reliable thermal stability so your compact JDM platform maintains optimum operating performance across daily commuting duty cycles.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67898425049336,"sku":"DS-ESUECO7MI","price":80.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/radiator-for-scion-xa-xb-2004-2006-1-5l-1.jpg?v=1793320919","url":"https:\/\/performancechiptuning.com\/de\/products\/radiator-for-scion-xa-xb-2004-2006-1-5l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
