Over time, internal calcification and external debris impact compromise coolant velocity across the tubes. More critically, corrosion of the internal transmission fluid cooler heat exchanger risks catastrophic cross-contamination between ATF and engine coolant, causing transmission slipping or warped cylinder heads on the \u003cstrong\u003eJ35Z4\u003c\/strong\u003e V6 platform.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered to exact OEM dimensions, this direct-swap cooling unit features an optimized aluminum core matched with high-density louvered fin arrays to accelerate convective heat dissipation. The single-row downflow configuration maximizes tube-to-fin surface area, preventing heat soak during towing or extended stop-and-go idling. Reinforced polymer tanks are mechanically swaged with robust sealing gaskets to withstand elevated operating pressures, while an integrated internal transmission oil cooler provides direct plug-and-play compatibility with OE hydraulic lines. Every production unit undergoes factory pneumatic pressure testing to guarantee leak-free reliability straight out of the box.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 Radiator (with built-in transmission oil cooler)\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;\"\u003e2009-2015 Honda Pilot\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;\"\u003eJ35Z4 (3.5L V6) \/ YF3 (2WD), YF4 (4WD)\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;\"\u003e250 hp \/ 253 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;\"\u003e13065, CU13065, 19010-RN0-A51, 19010-RN0-A52\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\u003e2009-2015 Honda Pilot 3.5L V6 (2WD Models - YF3 Chassis)\u003c\/li\u003e\n  \u003cli\u003e2009-2015 Honda Pilot 3.5L V6 (4WD Models - YF4 Chassis)\u003c\/li\u003e\n  \u003cli\u003e2009-2014 Honda Ridgeline 3.5L V6\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 YF3\/YF4 Pilot?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2009-2015 Honda Pilot equipped with the \u003cstrong\u003eJ35Z4\u003c\/strong\u003e 3.5L V6 engine across all 2WD and 4WD sub-models.\u003c\/p\u003e\n\n\u003ch4\u003eDo I need to bleed the air from the cooling system after installation?\u003c\/h4\u003e\n\u003cp\u003eYes, you must bleed all trapped air through the radiator filler neck until the cooling fans cycle twice and the engine achieves full operating temperature.\u003c\/p\u003e\n\n\u003ch3\u003eThe Honda Durability Standard\u003c\/h3\u003e\n\u003cp\u003eBuilt to handle continuous duty cycles, family hauling, and rated towing limits without thermal degradation, this cooling assembly maintains stable engine and transmission operating temperatures across all load demands.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67896249614584,"sku":"DS-E1GQ8HLUO","price":100.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/radiator-for-honda-pilot-2009-2015-3-5l-1.jpg?v=1793295554","url":"https:\/\/performancechiptuning.com\/products\/radiator-for-honda-pilot-2009-2015-3-5l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
