Part Number 2290 also includes the transmission oil cooler configuration required for this vehicle platform.

This radiator cross-references Spectra Premium CU2290 for the same application.

What This Radiator Helps Address

• Overheating caused by a restricted, leaking, or damaged radiator
• Transmission temperature concerns related to a failing integrated cooler
• Coolant loss from cracked tanks, worn seals, or core deterioration
• Reduced cooling efficiency on higher-mileage Mercedes-Benz E320 models
• Fitment issues from non-OE-style replacement radiators

Installation Notes and Tips

Verify core dimensions, inlet and outlet sizes, and cooler layout before installation on your Mercedes-Benz E320. This crossflow radiator is built for direct replacement use, and all necessary fittings or hardware are included in each unit. Confirm that the transmission cooler connections match the original setup before final assembly.

Quality Assurance

OSC tests the transmission and engine oil coolers before tank installation, checks the radiator core before assembly, and tests the completed unit again after assembly. The design also incorporates engineering updates aimed at improving durability and cooling performance in high-mileage vehicles. Part Number 2290 is built to meet OES cooler design requirements where originally equipped.
