Radiator for Mercedes Benz C-Class C300 C400 C450 AMG (2015-2016) 2.0L 3.0L

All-Aluminum Performance Radiator for 2015-2016 Mercedes Benz C-Class (W205)

What it Does: The all-aluminum performance radiator replaces the failure-prone factory heat exchanger on the 2015-2016 C-Class to lower coolant operating temperatures, maintain thermal equilibrium, and eliminate plastic end-tank blowouts.

The Stock Mercedes Benz C-Class Thermal Weakness

The factory cooling system in the W205 platform relies on an OEM radiator constructed with composite plastic end tanks mechanically crimped over an aluminum core with rubber sealing gaskets. Over continuous thermal cycles, the high operating pressures of the turbocharged M274 and biturbo M276 powerplants degrade this plastic resin. This thermal stress induces micro-cracking, gasket flattening, and eventual failure along the crimp seam, leading to sudden coolant loss, air cavitation, and severe cylinder head thermal distortion.

The Engineering Solution

Engineered as a robust direct replacement, this unit features 100% TIG-welded aluminum end tanks paired with a furnace-brazed 1-row tube-and-fin aluminum core. By replacing the composite materials with aircraft-grade aluminum, it eliminates brittle mechanical crimp joints. The high-efficiency fin pitch enhances surface area contact for improved convective heat transfer, resisting heat soak during heavy engine load and sustained highway speeds without requiring chassis modifications.

Frequently Asked Questions & Fitment Warnings

Does this fit the W205 C-Class?

Yes, this is a direct fit for the 2015-2016 Mercedes Benz C-Class equipped with the M274 2.0L or M276 3.0L engine. This radiator is not intended for C63 AMG V8 models or earlier W204 chassis variants.

Does this unit include an integrated transmission oil cooler?

No, an internal transmission oil cooler is not included; verify your existing auxiliary transmission cooling setup and hose routing prior to installation.
