Additional Notes

  • The Mercedes-Benz CLA-Class C117/X117 cooling system capacity splits into two distinct values across the lineup: 7.8 liters for the CLA 250 variants and 11.9 liters for the CLA 45 AMG 4MATIC, reflecting the greater thermal demands of the higher-output AMG engine.
  • The CLA 250 (117.344/944) and CLA 250 4MATIC (117.346/351/949/951) share an identical 7.8-liter cooling system capacity across the full 2013-2018 span, indicating no meaningful difference in cooling volume between the two-wheel-drive and all-wheel-drive configurations of the same engine family.
  • At 11.9 liters, the CLA 45 AMG 4MATIC cooling system holds roughly 53% more coolant than the CLA 250 variants, a difference consistent with the larger heat rejection requirements of a high-performance turbocharged engine operating at elevated output levels.
  • The CLA 45 AMG 4MATIC appears under two separate engine code groupings: 117.352 alone for 2013-2015, and 117.352/952 for 2015-2018. Both share the same 11.9-liter capacity and identical service interval, with the expanded code set in the later grouping indicating the addition of a related variant.
  • All four configurations carry a uniform coolant change interval of 144 months or 120,000 miles under normal use conditions, placing the service cycle at a 12-year or high-mileage threshold, whichever comes first.
  • A 144-month interval is notably long by general automotive standards, and under normal use conditions across all listed CLA-Class configurations, no shortened or alternate interval is specified.
