Detailed Description

This One Stop Solutions radiator, Part Number 2347, is designed around OE-style dimensions and cooling performance for 2000-2005 Buick LeSabre and 2000-2005 Pontiac Bonneville models with LCI. Core measurements include a 30 1/2-inch height, 15 1/16-inch width, and 5/8-inch thickness, with 1 5/16-inch inlet and 1 9/16-inch outlet diameters. The unit also includes a plated transmission oil cooler and is built with premium aluminum core materials and plastic tanks for a direct-fit replacement solution.

This part cross-references APDI 8012347 and Spectra Premium CU2347 for the same application.

Common Problems This Radiator Can Address

  • Coolant leaks from a worn or damaged radiator tank or core
  • Overheating caused by reduced heat transfer efficiency
  • Transmission fluid temperature concerns tied to a failing cooler circuit
  • Corrosion-related radiator deterioration in higher-mileage vehicles
  • Fitment issues from non-OE-style replacement parts

Installation Notes and Tips

Verify radiator dimensions, inlet and outlet sizes, and transmission cooler line spacing before installation. Confirm the vehicle is a 2000-2005 Buick LeSabre or 2000-2005 Pontiac Bonneville with LCI, and transfer any required fittings or related components from the original cooling system as needed. Flush the cooling system, inspect hoses and clamps, and check for proper fan operation after installation.

Quality Assurance

OSC radiators are pressure tested during production, including testing of the cooler circuits before tank installation and a final test after assembly. The design uses engineering updates aimed at improving durability and cooling performance in higher-mileage vehicles.
