Over time, heat cycles degrade the vulcanized crimp seal between the core and the PA66 plastic end tanks. This structural fatigue results in hairline fractures along the inlet neck, micro-fissuring, and eventual crimp seam separation under system pressure. Once integrity fails, rapid coolant loss reduces the system boiling point, causing severe heat soak and risking blown head gaskets.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis replacement radiator provides a true drop-in solution to stabilize operating temperatures. The unit features an efficient aluminum core utilizing high-density louvered fins engineered to maximize convective surface area and heat dissipation under heavy boost. High-strength polymer end tanks are mechanically crimped with durable header gaskets to resist internal pressure spikes. Built to original factory dimensions, it accommodates stock fan shrouds, hose diameters, and internal transmission cooler passages without chassis modification.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1x Complete Radiator Assembly\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;\"\u003e2011-2015 Kia Optima\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\u003eTheta II 2.0T GDI (G4KH)\u003c\/strong\u003e \/ \u003cstrong\u003eTF\u003c\/strong\u003e\n\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;\"\u003e274 hp \/ 269 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;\"\u003e\n\u003cstrong\u003e13189\u003c\/strong\u003e, \u003cstrong\u003eCU13189\u003c\/strong\u003e, \u003cstrong\u003e3757\u003c\/strong\u003e, \u003cstrong\u003e25310-3Q600\u003c\/strong\u003e, \u003cstrong\u003e25310-3S700\u003c\/strong\u003e, \u003cstrong\u003e25310-3S750\u003c\/strong\u003e, \u003cstrong\u003eHY3010173\u003c\/strong\u003e\n\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\u003e2011-2015 Kia Optima 2.0L Turbo (Automatic and Manual Transmissions)\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 TF Optima?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2011-2015 Kia Optima equipped with the \u003cstrong\u003eTheta II 2.0T\u003c\/strong\u003e engine. \u003cstrong\u003eThis radiator is designed exclusively for the 2.0L Turbo model and will not fit models equipped with the 2.4L naturally aspirated engine.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch4\u003eDo I need to bleed the cooling system after installing this radiator?\u003c\/h4\u003e\n\u003cp\u003eYes, thoroughly burp and bleed the cooling system to clear trapped air pockets from the engine block and turbo cooling circuit before operating the vehicle under load.\u003c\/p\u003e\n\n\u003ch3\u003eThe Kia Caliber\u003c\/h3\u003e\n\u003cp\u003eDesigned to maintain exact OEM thermal parameters, this radiator provides factory-level cooling capacity and dependable pressure containment for everyday commuting and high-load turbo performance.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67896136532216,"sku":"DS-E1AIF82I8","price":103.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/radiator-for-kia-optima-2011-2015-2-0l-turbo-1.jpg?v=1793292973","url":"https:\/\/performancechiptuning.com\/es\/products\/radiator-for-kia-optima-2011-2015-2-0l-turbo","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
