Over repeated heat cycles, cyclic thermal expansion embrittles the factory PA66 nylon end tanks, resulting in stress fractures along the crimped gasket header seams and upper inlet neck. Concurrently, internal scaling and core clogging restrict coolant cross-flow. When thermal dissipation degrades on the \u003cstrong\u003eTheta II\u003c\/strong\u003e engine, cylinder head temperatures spike rapidly, increasing combustion chamber knock vulnerability and risking head gasket failure.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered to standard \u003cstrong\u003eDPI 13191\u003c\/strong\u003e dimensional geometry, this drop-in replacement cooling assembly utilizes a high-efficiency aluminum tube-and-fin core paired with reinforced polymer end tanks. The aluminum core features optimized louvered fins and seamless multi-port cooling channels to maximize ambient air heat dissipation and convective efficiency. Integrated internal transmission oil cooler passages feature corrosion-resistant brass threaded fittings to handle automatic transaxle fluid pressures without cross-contamination. Every unit undergoes high-pressure thermal-shock cycle testing to guarantee a leak-free seal under standard closed-loop cooling system pressures.\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;\"\u003e2011-2014 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 Theta II (G4KJ) \/ YF\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;\"\u003e198 hp \/ 184 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;\"\u003e25310-3S000, 25310-3R000 (DPI 13191)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2011 Hyundai Sonata 2.4L\u003c\/li\u003e\n  \u003cli\u003e2012 Hyundai Sonata 2.4L\u003c\/li\u003e\n  \u003cli\u003e2013 Hyundai Sonata 2.4L\u003c\/li\u003e\n  \u003cli\u003e2014 Hyundai Sonata 2.4L\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the YF Sonata?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 2011-2014 Hyundai Sonata equipped with the 2.4L \u003cstrong\u003eTheta II\u003c\/strong\u003e engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this unit retain factory transmission cooling lines?\u003c\/strong\u003e\u003cbr\u003e Yes, it features integrated internal brass transcooler fittings that directly mate to the OEM transmission fluid cooler hardlines without modification.\u003c\/p\u003e\n\n\u003ch3\u003eThe Hyundai Commuter Standard\u003c\/h3\u003e\n\u003cp\u003eDaily driven commuters require dependable thermal stability through stop-and-go traffic and high ambient heat.
