The original equipment uses fiber-reinforced composite plastic end tanks crimped with an elastomeric gasket to an aluminum tube-and-fin core. Over sustained duty cycles, heat soak oxidizes the polymers, embrittling the upper neck and inlet ports until micro-cracks form under normal 13–16 PSI operating pressures. Furthermore, inner core tube scale buildup and external fin corrosion limit thermal transfer rates across the \u003cstrong\u003eSirius II (G4JS)\u003c\/strong\u003e and \u003cstrong\u003eDelta (G6BA\/G6BV)\u003c\/strong\u003e engine blocks, risking blown head gaskets and internal transmission fluid contamination via failed internal cooler lines.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered to standard \u003cstrong\u003eDPI 2339\u003c\/strong\u003e direct-replacement specifications, this unit restores nominal operating temperatures with upgraded structural integrity. The core is constructed with high-efficiency, multi-louvered aluminum cooling fins brazed to micro-extruded cooling tubes for maximum coolant-to-air thermal exchange. Reinforced virgin polymer tanks resist pressure deformation and localized thermal stress at hose spigots. Integrated brass transmission oil cooler fittings provide corrosion-resistant, leak-free fluid isolation for automatic transaxles, dropping straight into factory rubber isolator mounts without bracket modifications.\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;\"\u003e1999-2005 Hyundai Sonata\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;\"\u003e2.4L G4JS, 2.5L G6BV, 2.7L G6BA \/ EF\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;\"\u003e138–178 hp \/ 147–181 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;\"\u003eDPI 2339, 25310-38050\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1999-2005 Hyundai Sonata 2.4L L4 (G4JS Engine)\u003c\/li\u003e\n  \u003cli\u003e1999-2001 Hyundai Sonata 2.5L V6 (G6BV Engine)\u003c\/li\u003e\n  \u003cli\u003e2002-2005 Hyundai Sonata 2.7L V6 (G6BA Engine)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the EF Sonata?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 1999-2005 Hyundai Sonata equipped with the G4JS, G6BV, or G6BA engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this radiator support both manual and automatic transmission setups?\u003c\/strong\u003e\u003cbr\u003e Yes, it includes internal brass transmission oil cooler fittings that can simply be left plugged for manual applications without altering function.\u003c\/p\u003e\n\n\u003ch3\u003eThe Hyundai Reliability Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered for uninterrupted daily drivability, this replacement radiator provides tight thermal margins and dependable heat transfer to keep your Hyundai powertrain running at peak mechanical reliability.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50551415341304,"sku":"DS-EHANUWW4H","price":159.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/radiator-for-hyundai-sonata-1999-2005-2-4l-2-5l-2-7l-1.jpg?v=1789776413","url":"https:\/\/performancechiptuning.com\/es\/products\/radiator-for-hyundai-sonata-1999-2005-2-4l-2-5l-2-7l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
