Continuous thermal cycling from the Gen IV V8 engines degrades these polymer tanks over time, causing stress cracking, brittle tank failure, and leaks at the crimp joints. Under sustained towing or aggressive driving, the OEM core density struggles to shed heat efficiently, compromising both engine and automatic transmission operating temperatures.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eConstructed entirely from aircraft-grade AA5052 aluminum, this radiator features 100% TIG-welded tanks and a high-efficiency racing core design to eliminate mechanical crimp seams. The downflow core maximizes surface contact area to increase convective heat transfer under high thermal loads. It includes an integrated internal transmission oil cooler and a billet-style filler neck with radiator cap, providing a heavy-duty bolt-on replacement.\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;\"\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eFitment\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e2006-2009 Chevrolet Trailblazer (5.3L \u0026amp; 6.0L V8)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eEngine \/ Chassis\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eLH6, LS2 \/ GMT360\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eStock Output\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e300–395 hp \/ 321–400 lb-ft\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003ePart Number \/ MPN\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eAN67338 (Interchange: DPI 2563, CU2563, CC2563, DP2563)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eCore Dimensions\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e18.11 in x 26.69 in x 1.02 in (AA5052 Aluminum)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eInlet \/ Outlet Diameter\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e1.26 in (Inlet) \/ 1.57 in (Outlet)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2006-2008 Chevrolet Trailblazer 5.3L V8 (LH6)\u003c\/li\u003e\n  \u003cli\u003e2006-2009 Chevrolet Trailblazer SS 6.0L V8 (LS2)\u003c\/li\u003e\n  \u003cli\u003e\u003cem\u003eNote: Excludes 4.2L Inline-6 models due to core and bracket variations.\u003c\/em\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Chevrolet Heavy-Duty Caliber\u003c\/h3\u003e\n\u003cp\u003eEngineered to handle sustained high-load towing and high-displacement V8 heat cycles, delivering dependable cooling capacity and structural durability without the risk of plastic tank fatigue.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50459250426104,"sku":"DS-EKJ5Y6833","price":195.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/performance-radiator-for-chevrolet-trailblazer-2006-2009-5-3l-6-0l-1.jpg?v=1788809191","url":"https:\/\/performancechiptuning.com\/products\/performance-radiator-for-chevrolet-trailblazer-2006-2009-5-3l-6-0l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
