Detailed Description

OSC part number 453 is a replacement radiator for Mercedes-Benz cooling systems that require a crossflow layout and integrated transmission cooling. The radiator uses premium aluminum tubes and fins, plastic tanks, and cadmium-plated tubes inside and out to help resist premature failure. It is engineered around OES-style dimensions and includes the transmission oil cooler in a concentric configuration, making it a practical choice for Mercedes-Benz E320, 300E, 300CE, and 300TE service work where correct fit and cooling performance matter.

This part cross-references APDI 8010453 for the same application.

What It Helps Address

• Coolant leaks from an aging or cracked radiator
• Overheating caused by reduced core efficiency
• Transmission temperature concerns tied to a failing cooler circuit
• Fitment issues from non-OE-style replacement radiators
• Cooling loss on higher-mileage Mercedes-Benz 300E and E320 vehicles

Installation Notes and Tips

Verify core size, inlet and outlet diameter, and transmission cooler layout before installation. This radiator is listed for select Mercedes-Benz 300E, 300CE, 300TE, and E320 models, including 21-inch core applications. Confirm the vehicle’s original cooling configuration against the part number 453 specifications to ensure proper alignment with the factory mounting points and hose connections.

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. Each radiator is individually pressure tested and built to meet OES cooler design requirements where originally equipped.
