Additional Notes

  • The Mercedes-Benz GLE-Class W166 GLE 350 4MATIC (166.057) carries a main cooling system capacity of 10.5 liters, which represents the total service fill volume for the primary engine cooling circuit across the 2015-2019 model years.
  • A separate intercooler circuit on the GLE 350 4MATIC holds 1.9 liters, meaning the two cooling circuits together account for 12.4 liters of total coolant volume when both are serviced.
  • The GLE 350 4MATIC cooling system and intercooler share a change interval of 144 months or 120,000 miles under normal use conditions, whichever comes first.
  • The GLE 400 4MATIC (166.056) matches the GLE 350 4MATIC in both main cooling system capacity (10.5 liters) and intercooler capacity (1.9 liters), yet carries a notably longer change interval of 180 months or 150,000 miles under normal use conditions.
  • The GLE 550 4MATIC (166.073) has the largest main cooling system capacity among the W166 configurations listed, at 12.9 liters, which reflects the greater thermal demands of the larger displacement V8 engine in the 2015-2018 model years.
  • The GLE 63 AMG (166.074) main cooling system holds 8 liters, while the GLE 63 S AMG (166.075) holds a slightly smaller 7.5 liters, showing a measurable difference between the two AMG variants despite sharing the same basic engine family.
  • The GLE 63 AMG intercooler circuit carries 2 liters of coolant, which is 0.1 liters more than the intercooler capacity specified for the GLE 350 4MATIC and GLE 400 4MATIC.
  • Both the GLE 63 AMG and GLE 63 S AMG share a change interval of 150,000 miles or 180 months under normal use conditions, aligning with the longer interval also specified for the GLE 400 4MATIC rather than the shorter interval of the GLE 350 4MATIC.
