Few things get your attention as quickly as seeing white smoke billowing out from under the hood—and once stopped, precious anti-freeze all over the ground. OSC Automotive radiators are designed to fit into place as easily as the stock model came out; OEM models are used as a baseline, so their radiators meet or exceed the originals.

To ensure great products, OSC starts with the highest grade of raw components, then follows factory construction standards to maintain longevity of the engine and transmission. Transmission and oil coolers are tested before installation on needed units, and radiator cores are qualified before and after assembly using state-of-the-art cycle, vibration, burst, and environment testing. OSC prides itself on solving OE design failures in order to provide radiators with better life expectancies than the originals. Over a thousand models are available for fitment on specific makes and models. Choose the style designed for your engine type and vehicle application.
