Detailed Description

This radiator is designed for drivers replacing a worn or leaking cooling unit in a Buick Allure, Buick LaCrosse, Chevrolet Monte Carlo, or Chevrolet Impala. Part number 2827 follows OE form and function with premium tubes, fins, headers, and tanks, plus engineering updates aimed at improving cooling performance and service life on higher-mileage vehicles. The unit also includes a plated transmission oil cooler and is built with a crossflow configuration to match the original cooling layout where equipped.

OSC radiators are assembled with factory-spec component fitment and torque, then pressure tested during production to verify the core and cooler sections before final assembly and again after assembly. This part cross-references Spectra Premium CU2827 and Koyorad A2827 for the same application.

Common Problems This Radiator Can Address

• Coolant leaks from a cracked or aging radiator tank
• Overheating caused by restricted or inefficient heat transfer
• Transmission fluid temperature concerns related to a failing cooler circuit
• Fitment issues from a damaged or previously repaired radiator
• Cooling system service needs on high-mileage Chevrolet Impala, Monte Carlo, Buick Allure, or LaCrosse models

Installation Notes and Tips

Verify core dimensions, inlet and outlet sizes, and cooler line spacing before installation. Confirm vehicle application details for 2005-2008 Buick Allure and LaCrosse, 2006-2007 Chevrolet Monte Carlo, and 2006-2011 Chevrolet Impala, including the Impala note for vehicles without the police package. Inspect hoses, clamps, and cooler lines for wear before transferring the radiator into service.

Quality Assurance

OSC builds this radiator with cadmium-plated tubes to help resist premature failure and uses a die-cut gasket to support leak control. Each unit is pressure tested during production, and the design is updated to address known failure points while maintaining OE-style fit and function.
