Additional Notes

  • Cooling system capacity across the Mercedes-Benz CLK-Class C208/A208 range scales with engine displacement, running from 8 liters in the four-cylinder variants up to 11 liters in the V8-powered CLK 430 and CLK 55 AMG.
  • The CLK 200 Kompressor is the only variant in the lineup with a transmission-dependent coolant capacity. Pairing with an automatic transmission raises the figure to 8.5 liters, while the manual transmission configuration holds 8 liters, matching the naturally aspirated CLK 200.
  • The supercharged CLK 200 Kompressor's higher coolant volume with the automatic gearbox reflects the additional thermal load introduced by the transmission cooler circuit, which is typically integrated into the engine cooling loop on vehicles of this era.
  • Despite the CLK 230 Kompressor also carrying a supercharged four-cylinder engine, its cooling system capacity is listed at 8 liters regardless of transmission type, differing from the CLK 200 Kompressor's automatic-transmission variant.
  • The CLK 320, equipped with a 3.2-liter V6, carries a 9-liter cooling system capacity, placing it between the four-cylinder and V8 figures and consistent with the greater coolant jacket volume associated with a six-cylinder block.
  • Both V8 variants, the CLK 430 and CLK 55 AMG, share an 11-liter cooling system capacity. At 11 liters, these represent the largest coolant volumes in the C208/A208 specification set, reflecting the greater surface area and thermal output of the larger displacement engines.
  • All six variants across the 1997-2002 model range share a uniform 36-month coolant change interval under normal use conditions, indicating a consistent service schedule regardless of engine type or capacity.
  • The CLK 55 AMG entered the lineup for the 1999-2002 period, a shorter production window than the other variants, yet carries the same 36-month interval and 11-liter capacity as the CLK 430 despite its higher-performance AMG specification.
