Over repeated thermal cycles, the differential expansion rates between polymer and aluminum cause micro-fractures, gasket degradation, and catastrophic pressure loss along the tank seams. Additionally, stock single-row cores lack the thermal capacity to shed sustained fluid temperatures during aggressive driving, leading to elevated coolant and transmission fluid heat soak on 6.0L and 6.2L applications.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eConstructed from high-tensile AA5052 aircraft-grade aluminum, this direct-fit downflow radiator features 2 mm thick TIG-welded tanks and a vacuum-brazed 4-row tube core. Multi-louvered cooling fins spaced at 14–16 FPI (fins per inch) maximize ambient air turbulence and convective heat transfer without restricting engine bay airflow. An integrated internal transmission oil cooler (TOC) ensures synchronized fluid stabilization, while a CNC-machined filler neck and heavy-duty brass petcock prevent fluid loss under high-pressure cooling scenarios.\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;\"\u003e2008-2009 Pontiac G8 (Automatic Only)\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;\"\u003e6.0L L76, 6.2L LS3 \/ GM Zeta\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;\"\u003e361–415 hp \/ 385–415 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;\"\u003e92191918, 92216759, 92234040, 92253248\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2008 Pontiac G8 GT 6.0L V8 Automatic\u003c\/li\u003e\n  \u003cli\u003e2009 Pontiac G8 GT 6.0L V8 Automatic\u003c\/li\u003e\n  \u003cli\u003e2009 Pontiac G8 GXP 6.2L V8 Automatic\u003c\/li\u003e\n  \u003cli\u003e\u003cem\u003eNote: Does not fit Pontiac GTO or manual transmission models without external cooler modifications.\u003c\/em\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Pontiac Performance Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to handle the immense thermal output of high-displacement GM small-block V8s, this heavy-duty cooling assembly prevents power-robbing timing retard and maintains optimal engine and transmission operating temperatures under maximum load.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50416638853368,"sku":"DS-E7QBQ65MZ","price":349.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/performance-radiator-for-pontiac-g8-2008-2009-6-0l-6-2l-automatic-1.jpg?v=1788323325","url":"https:\/\/performancechiptuning.com\/fr\/products\/performance-radiator-for-pontiac-g8-2008-2009-6-0l-6-2l-automatic","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
