Decades of heat-cycling embrittle the plastic, leading to stress fractures at the tank seams and hose necks. Under repeated thermal expansion, the internal rubber gasket deteriorates, resulting in pressure loss, boil-overs, and elevated cylinder head temperatures on the 3.6L LY7 powerplant.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis assembly upgrades the cooling circuit with a 100% furnace-brazed aluminum 3-row core and precision TIG-welded end tanks, eliminating failure-prone crimped gaskets entirely. The engineered aluminum shroud focuses airflow evenly across the entire fin area rather than pulling air through localized dead zones. Paired with a dedicated electric fan and relay harness, it provides consistent heat rejection and combats heat soak in stop-and-go traffic.\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;\"\u003e2005-2008 Buick LaCrosse\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;\"\u003e3.6L LY7 High Feature V6 \/ 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;\"\u003e240 hp \/ 225 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\u003e2005 Buick LaCrosse CXS 3.6L V6\u003c\/li\u003e\n  \u003cli\u003e2006 Buick LaCrosse CXS 3.6L V6\u003c\/li\u003e\n  \u003cli\u003e2007 Buick LaCrosse CXS 3.6L V6\u003c\/li\u003e\n  \u003cli\u003e2008 Buick LaCrosse CXS 3.6L V6\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Buick Reliability Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to deliver long-term thermal stability, this direct replacement radiator safeguards the LY7 engine against catastrophic overheating, ensuring seamless daily drivability and sustained cooling efficiency without custom modifications.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50497320517880,"sku":"DS-EHGUXP4M1","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-buick-lacrosse-2005-2008-3-6l-1.jpg?v=1789257985","url":"https:\/\/performancechiptuning.com\/es\/products\/aluminum-radiator-with-shroud-for-buick-lacrosse-2005-2008-3-6l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
