Direct-fit replacement radiator engineered to match OE durability and cooling performance for select 2000-2005 Buick LeSabre and Pontiac Bonneville models. Precision-formed core and reinforced side rails reduce stress and resist warping from thermal expansion. Increased tube wall thickness and corrosion-resistant fins improve longevity while maintaining efficient heat transfer. Plastic/aluminum construction balances weight and strength for dependable service life. Redesigned corner brackets and OE-style mounting points simplify installation and ensure secure fitment. Integrated transmission oil cooler ports maintain proper transmission temperatures on equipped vehicles. Manufactured and tested to meet industry performance standards for pressure and leak resistance. Finished connectors and robust inlet/outlet ports deliver reliable sealing and reduced maintenance risk. Backed by Spectra Premium quality controls for consistent, vehicle-specific replacement performance.
