OSC 13200SD Severe Duty Replacement Radiator

The OSC 13200SD is a severe duty replacement radiator engineered to deliver reliable, high-performance cooling. Designed to OES (Original Equipment Standard) form and function, this radiator installs as a direct replacement with no modifications required, restoring your cooling system to factory performance or better.

OSC radiators are constructed from premium-grade aluminum with cadmium-plated tubes — inside and out — to resist corrosion and prevent premature failure. OSC does not substitute inferior aluminum coolers in place of stainless steel plate or copper and brass concentric coolers, ensuring you receive a unit that meets the original design intent. A die-cut gasket is included to provide a leak-free seal.

Key Features:

• Severe duty construction for demanding driving conditions and high-mileage applications
• Premium-grade aluminum core with cadmium-plated tubes for corrosion resistance
• Meets OES cooler design — copper concentric coolers and plate coolers where originally equipped
• Die-cut gasket included for leak-free installation
• Individually pressure tested before leaving the factory
• Engineered for multi-fit precision without compromising look or fitment
• All necessary fittings and hardware included

Each OSC 13200SD radiator undergoes rigorous pressure testing both at the core stage and again after final assembly, ensuring the unit meets strict performance standards before it ships. This is a 100% brand-new unit — not remanufactured — built to provide dependable engine temperature control and long service life.
