Over time, repeated thermal expansion cycles cause the plastic end tanks to embrittle and develop hairline fractures, particularly around the 1 5\/16-inch upper inlet neck and crimp seams. Additionally, factory single- and dual-row cores struggle with thermal saturation and heat soak during high-ambient operation or heavy payload hauling, compromising both engine block and transmission cooling circuits.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis direct replacement cooling assembly features a high-efficiency 3-row crossflow core constructed entirely from aircraft-grade aluminum, joined to heavy-gauge end tanks with precision TIG welds to permanently eliminate mechanical crimp seam failures. The oversized 34-inch wide by 17 1\/4-inch high core increases liquid volume and cooling fin contact area compared to standard 28-inch units. It integrates heavy-duty cooling circuits internally, featuring an integrated transmission fluid cooler on the passenger side and an auxiliary engine oil cooler on the driver side to stabilize high-temperature driveline fluids.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1x 3-Row All-Aluminum Crossflow Radiator with Integrated Transmission and Engine Oil Coolers\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;\"\u003e2008-2013 Chevrolet Silverado\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;\"\u003eGen IV Vortec (4.8L, 5.3L, 6.0L) \/ GMT900\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;\"\u003e295–367 hp \/ 305–380 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;\"\u003eCU2370, 2370, REA41-13029A, 22840116, 52486594, 52487603, 25811504, 15841570, 20935856, 15143107\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\u003e2008-2013 Chevrolet Silverado 4.8L V8\u003c\/li\u003e\n  \u003cli\u003e2008-2013 Chevrolet Silverado 5.3L V8\u003c\/li\u003e\n  \u003cli\u003e2008-2009 Chevrolet Silverado 6.0L V8\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 GMT900 Silverado?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2008-2013 Chevrolet Silverado equipped with the \u003cstrong\u003eGen IV Vortec\u003c\/strong\u003e 4.8L, 5.3L, and 6.0L engines. \u003cstrong\u003eThis unit does not fit 2010-2013 Chevrolet Silverado 1500 6.0L models, and requires verification of the 34-inch core length between tanks prior to purchase.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch4\u003eHow do I confirm core size before ordering?\u003c\/h4\u003e\n\u003cp\u003eMeasure the finned core width between the aluminum end tanks; this unit strictly replaces the 34-inch core size and will not fit trucks equipped with the smaller 28-inch radiator core.\u003c\/p\u003e\n\n\u003ch3\u003eThe Chevrolet Hauling Caliber\u003c\/h3\u003e\n\u003cp\u003eEngineered for high-demand work trucks, this heavy-duty aluminum assembly provides the structural rigidity and thermal margin required for severe-duty hauling, payload carrying, and extended highway towing.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67563020222712,"sku":"DS-E1138JO9R","price":168.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/radiator-for-chevrolet-silverado-2008-2013-4-8l-5-3l-6-0l-1.jpg?v=1790999246","url":"https:\/\/performancechiptuning.com\/es\/products\/radiator-for-chevrolet-silverado-2008-2013-4-8l-5-3l-6-0l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
