OSC Premium New Automotive Radiator is designed to OES form and function. OSC radiators are technically advanced and made from premium grade aluminum. The tubes are cadmium plated inside and out to prevent premature failure. OSC does not substitute aluminum coolers in place of Stainless Steel plate or Copper and Brass concentric coolers and they use a die cut gasket to ensure there are no leaks. Each radiator is individually pressure tested and engineered for multi-fit without compromising the look and fit. All necessary fittings or hardware are included in each unit. All units meet OES cooler design with copper concentric coolers and plate coolers where originally equipped.

OSC Automotive® is your one-stop shop for top-quality replacement heat transfer and ride control products, designed to meet or exceed OEM parts. The company offers its high-quality radiators, condensers, heaters, shocks, struts, steering stabilizers, and more efficient products for you to enjoy a smooth, hassle-free driving experience. Each end every OSC product is tested up to 3 times during production, including vibration, burst, and environmental testing. The results are then used to create a product with even greater durability and better performance. OSC Automotive knows the value of investing in the future and is constantly looking forward to the new technologies of tomorrow.
