After decades of thermal cycling, these plastic tanks become brittle, leading to micro-fractures, catastrophic cracking, and sudden coolant pressure loss. Furthermore, the factory core thickness is insufficient for sustained high-RPM driving or track use, leading to rapid heat soak. The restrictive fin pitch struggles to dissipate the thermal load generated by the 1UZ-FE block, causing temperature spikes that trigger the ECU to retard timing, thereby reducing power output and risking premature head gasket failure.\u003c\/p\u003e\n\n\u003ch3\u003eThe All-Aluminum Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis high-performance radiator eliminates OEM failure points by utilizing 100% TIG-welded aluminum construction with no epoxy. The core is bonded in a vacuum brazing furnace for superior structural integrity. Thermal efficiency is dramatically improved through a heavy-duty 3-row tube design. By shrinking the cooling row spacing to 3\/8-inch, this core fits 25% more rows than standard aftermarket units. Coupled with a dense louvered fin design packing 14 to 16 fins per inch (totaling roughly 1500 additional fins), the active heat dissipation surface area is maximized. This fluid dynamics optimization results in a 35% to 45% increase in cooling efficiency over stock, ensuring stable coolant temperatures during aggressive driving and preserving engine longevity.\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;\"\u003e1992-1997 Lexus SC400\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;\"\u003e1UZ-FE \/ UZZ30\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;\"\u003e250 hp \/ 260 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;\"\u003e16400-50060, 16400-50062, 1306\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1992 Lexus SC400 4.0L V8 GAS\u003c\/li\u003e\n  \u003cli\u003e1993 Lexus SC400 4.0L V8 GAS\u003c\/li\u003e\n  \u003cli\u003e1994 Lexus SC400 4.0L V8 GAS\u003c\/li\u003e\n  \u003cli\u003e1995 Lexus SC400 4.0L V8 GAS\u003c\/li\u003e\n  \u003cli\u003e1996 Lexus SC400 4.0L V8 GAS\u003c\/li\u003e\n  \u003cli\u003e1997 Lexus SC400 4.0L V8 GAS\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Lexus JDM Caliber\u003c\/h3\u003e\n\u003cp\u003eEngineered for the Z30 chassis, this cooling upgrade ensures your 1UZ-FE maintains consistent power delivery and thermal stability, unlocking the true endurance potential of classic JDM engineering.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50111082955000,"sku":"DS-EREDFZL5R","price":209.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/performance-radiator-for-lexus-sc400-1992-1996-4-0l-1.webp?v=1785859707","url":"https:\/\/performancechiptuning.com\/es\/products\/performance-radiator-for-lexus-sc400-1992-1996-4-0l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
