Over continuous thermal cycling, the plastic undergoes brittle degradation, leading to micro-fractures along the header plate crimps and upper tank neck. Furthermore, OEM core density is insufficient for sustained performance driving or high ambient temperatures, causing heat soak that compromises engine longevity and automatic transmission fluid stability.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eConstructed entirely from 2.0 mm AA5052 aircraft-grade aluminum, this unit features 100% TIG-welded tanks with a vacuum-brazed 3-row racing core. Cooling rows are pitched at 3\/8-inch intervals with a dense 14-16 fins-per-inch (FPI) profile to maximize thermal transfer efficiency. It incorporates an internal brass transmission oil cooler (TOC), a CNC-machined billet filler neck, and an OEM-style brass petcock drain for long-term structural reliability without plastic fatigue.\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;\"\u003e1998-2005 Lexus GS (Automatic)\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;\"\u003e2JZ-GE, 1UZ-FE \/ S160 (JZS160, UZS160)\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;\"\u003e225-300 hp \/ 220-310 lb-ft\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eCore Dimensions\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e16.14 in x 29.92 in (Overall: 20.87 in x 30.31 in)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eInlet \/ Outlet\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e1.34 in \/ 1.34 in\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\u003e1998-2005 Lexus GS300 3.0L I6 Automatic (S160 \/ JZS160)\u003c\/li\u003e\n  \u003cli\u003e1998-2000 Lexus GS400 4.0L V8 Automatic (S160 \/ UZS160)\u003c\/li\u003e\n  \u003cli\u003e1998-2005 Toyota Aristo 3.0L 2JZ-GTE Turbo Automatic (JZS161)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNote:\u003c\/strong\u003e Does not fit 1993-1997 Lexus GS (S140 chassis)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Lexus JDM Performance Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to handle elevated coolant pressures and extreme thermal loads, this radiator delivers optimal operating temperatures for both naturally aspirated and boosted 2JZ\/1UZ platforms while preserving transmission integrity.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50416619847928,"sku":"DS-E6HFCRBS9","price":229.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/performance-radiator-for-lexus-gs-1998-2005-3-0l-4-0l-automatic-1.jpg?v=1788323037","url":"https:\/\/performancechiptuning.com\/products\/performance-radiator-for-lexus-gs-1998-2005-3-0l-4-0l-automatic","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
