C63 / C63 S Platform • Heat Management Upgrade

CSF Auxiliary Radiators for Mercedes C63 & C63 S AMG (W205)

High-capacity all-aluminum auxiliary radiators engineered to reduce heat soak, stabilize coolant temperatures, and maintain consistent power on the M177 4.0L BiTurbo V8 platform.

The CSF Auxiliary Radiators for the Mercedes C63 & C63 S AMG address one of the biggest limitations of the M177 platform: heat management. Factory auxiliary radiators struggle once the car is driven hard — especially on tuned setups, spirited canyon runs, or repeated pulls.

CSF’s upgraded radiators increase coolant volume and heat rejection, helping the C63 maintain stable temperatures and consistent power delivery under sustained load.

Engineering & Construction

• All-aluminum construction for improved heat dissipation
• High-efficiency multi-row core design
• Increased coolant capacity over factory auxiliary radiators
• Optimized fin density for maximum airflow and cooling
• Optional protective rock guards (model dependent)

Why C63 Owners Upgrade

• Lower and more consistent coolant temperatures
• Reduced heat soak during repeated acceleration
• Improved reliability on tuned vehicles
• Additional thermal headroom for downpipes and ECU tuning

Vehicle Compatibility

• Mercedes C63 AMG (W205)
• Mercedes C63 S AMG (W205)

Designed for vehicles equipped with the M177 4.0L BiTurbo V8 engine. Recommended to replace left and right auxiliary radiators together for best results.
