Product Description

The OSC Premium radiator 2831E is engineered to match original cooler design where equipped, while using a die-cut gasket to help maintain a leak-resistant seal. The unit is built with a single-row core, aluminum transmission oil cooler, and factory-style inlet and outlet sizing for a straightforward replacement in supported Hyundai Sonata, Hyundai Azera, Kia Optima, and Kia Magentis applications. OSC pressure tests each radiator during production and uses design updates aimed at improving durability in higher-mileage vehicles.

Common Issues This Radiator Can Address

• Coolant loss from a leaking radiator tank or seal

• Transmission temperature concerns when the cooler circuit is part of the failure
• Reduced cooling performance from aged core materials
• Fitment problems from a damaged or incorrect replacement radiator

This radiator is intended for economy-version fitments only, so confirm the vehicle’s original cooling package matches the listed application. The part number 2831E should be matched to the existing unit before removal.
