Detailed Description

OSC part number 1518 is a premium replacement radiator designed for OE-style fit, form, and function in select GM vehicles. It uses premium-grade aluminum tubes and fins, cadmium-plated tubes inside and out, and a plated transmission cooler where equipped. The radiator is engineered for multi-fit applications without changing the original appearance or mounting profile, and all required fittings or hardware are included in each unit. For drivers servicing a Chevrolet Lumina, Chevrolet Monte Carlo, Buick Regal, or Oldsmobile Cutlass Supreme, this radiator provides a direct replacement solution built around the original cooling system layout.

This part cross-references APDI 8011518 and Four Seasons 20693 for the same application.

Common Cooling System Issues It Can Address

• Coolant leaks from a cracked or aging radiator tank
• Overheating caused by reduced core efficiency
• Transmission fluid temperature concerns tied to a failing cooler circuit
• Corrosion-related radiator deterioration in high-mileage vehicles
• Poor heat transfer from a restricted or damaged core

Installation Notes and Tips

Verify core dimensions, inlet and outlet size, and transmission cooler line spacing before installation. This radiator is a crossflow design with a 1 5/16" inlet and outlet, so matching the original hose and cooler connections is important for proper fitment. Inspect mounting points, hoses, and clamps during replacement to help prevent leaks and repeat cooling-system failures.

Quality Assurance

OSC tests the transmission and engine oil coolers before tank installation, checks the radiator core before assembly, and tests the completed unit again after assembly. Each radiator is individually pressure tested to confirm sealing and performance before it leaves production.
