Over decades of heat cycles and pressure variations, these composite tanks embrittle, frequently cracking at the upper hose neck or leaking along the crimp seam. Additionally, the restricted fluid capacity of the factory core struggles with heat soak under aggressive driving or hot ambient conditions, elevating coolant temperatures and stressing the engine assembly.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eConstructed entirely from aircraft-grade aluminum, this 4-row performance radiator features furnace-brazed core tubes and precision TIG-welded tanks to eliminate vulnerable crimp seals and plastic components. The high-density louvered fin design exponentially increases core surface area, accelerating thermal dissipation and overall cooling efficiency. Engineered as a direct bolt-in unit, it restores thermal stability while accommodating factory mounting points and transmission cooler lines.\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;\"\u003e2000-2003 Buick Regal\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;\"\u003eGM 3800 Series II (L36 \/ L67) \/ 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;\"\u003e200 - 240 hp \/ 225 - 280 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\u003e2000 Buick Regal (3.5L, 3.8L V6)\u003c\/li\u003e\n  \u003cli\u003e2001 Buick Regal (3.5L, 3.8L V6)\u003c\/li\u003e\n  \u003cli\u003e2002 Buick Regal (3.5L, 3.8L V6)\u003c\/li\u003e\n  \u003cli\u003e2003 Buick Regal (3.5L, 3.8L V6)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Buick Touring Caliber\u003c\/h3\u003e\n\u003cp\u003eBuilt to handle the demanding torque output of the GM 3800 platform, this all-aluminum radiator delivers long-term thermal endurance, preventing catastrophic coolant loss and maintaining peak power delivery whether cruising the open highway or pushing supercharged boost levels.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50496511639800,"sku":"DS-EZYG7OQF6","price":269.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/aluminum-radiator-for-buick-regal-2000-2003-3-5l-3-8l-1.jpg?v=1789245381","url":"https:\/\/performancechiptuning.com\/products\/aluminum-radiator-for-buick-regal-2000-2003-3-5l-3-8l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
