OSC Radiator 730
Radiator. (730) by OSC
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.
