Over repeated heat cycles in the transverse engine bay of the 3.5L and 3.9L V6, the factory plastic tanks become brittle, predisposing the assembly to hairline fractures, crimp seam weeping, and sudden pressure discharge. Furthermore, the shallow factory single-row core struggles with heat soak during extended idling or high ambient temperatures, diminishing air conditioning performance and raising transmission fluid temperatures.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis cooling upgrade incorporates a high-density 3-row brazed aluminum tube-and-fin core with TIG-welded structural tanks, eliminating failure-prone elastomeric seals and plastic end caps. The high-conductivity aluminum matrix expands fluid capacity and maximizes heat rejection across the core face. Paired with a form-fitted aluminum fan shroud and high-output electric cooling fan with a relay harness, this assembly directs focused airflow across the entire fin surface to prevent hotspot formation and sustain thermal stability during heavy stop-and-go operation.\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;\"\u003e2006-2011 Chevrolet Impala\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;\"\u003e3.5L LZ4 \/ 3.9L LZ9 V6 (High Value) \/ GM W-Body\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;\"\u003e211–242 hp \/ 214–242 lb-ft (Approx)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003ePart Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eN\/A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2006-2011 Chevrolet Impala LS (3.5L V6 LZ4)\u003c\/li\u003e\n  \u003cli\u003e2006-2011 Chevrolet Impala LT (3.5L V6 LZ4, 3.9L V6 LZ9)\u003c\/li\u003e\n  \u003cli\u003e2006-2010 Chevrolet Impala LTZ (3.9L V6 LZ9)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Chevrolet Reliability Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to handle severe fleet and highway duty cycles, this all-aluminum cooling assembly delivers sustained heat management to preserve engine internals and integrated transmission circuits through heavy-load operation and high ambient conditions.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50497320681720,"sku":"DS-EQOFM9QIG","price":308.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/aluminum-radiator-with-shroud-for-chevrolet-impala-2006-2011-3-5l-3-9l-1.jpg?v=1789258013","url":"https:\/\/performancechiptuning.com\/fr\/products\/aluminum-radiator-with-shroud-for-chevrolet-impala-2006-2011-3-5l-3-9l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
