Detailed Product Description

OSC part number 2190 is a replacement radiator engineered for Mercedes-Benz ML320, ML430, and ML500 applications. The unit uses a 24-inch core height, 21 9/16-inch core width, and 1-1/4-inch core thickness, with 1 7/16-inch inlet and outlet diameters. It also includes both engine and transmission oil cooling provisions, matching the original cooling layout where equipped.

The radiator is built with premium materials and assembled to factory specifications for fit and function. OSC adds design improvements such as increased fin density, thicker core construction, and larger transmission cooler capacity to address heat load in higher-mileage vehicles. This part cross-references Spectra Premium CU2190 for the same application.

Common Cooling Problems This Radiator Can Address

• Overheating caused by a leaking or restricted radiator
• Transmission fluid temperature issues related to a failing cooler circuit
• Coolant loss from cracked tanks or weakened seals
• Reduced cooling efficiency from aged core materials
• Fitment problems after replacing a damaged original radiator

Installation Notes and Tips

Verify the vehicle’s cooling layout before installation, especially the transmission and engine oil cooler connections. Inspect hoses, clamps, and mounting points for wear before transferring the new radiator into place. Confirm inlet and outlet alignment and check for proper sealing after installation.

Quality Assurance

OSC tests the transmission and engine oil coolers before tank installation, checks the radiator core prior to assembly, and tests the completed unit again after assembly. Each radiator is individually pressure tested to help confirm leak resistance and consistent performance.
