Mercedes-Benz AMG GT 4-Doors, X290 (EU)

Additional Notes

• Across the Mercedes-Benz AMG GT 4-Door X290 lineup, all coolant service intervals are set at 200,000 km or 120 months under normal use conditions, regardless of variant or engine configuration.
• The AMG GT 43 and AMG GT 43 4MATIC+ variants (290.658 and 290.659) share identical coolant capacities: 14 liters for the main cooling system and 4 liters for the separate intercooler circuit.
• The AMG GT 53 4MATIC+ (290.661) also carries a 14-liter main cooling system capacity and a 4-liter intercooler circuit, matching the GT 43 figures exactly.
• The AMG GT 63 4MATIC+ (290.688) and AMG GT 63 S 4MATIC+ (290.689) both require 15.3 liters for the main cooling system, a larger fill volume than the six-cylinder variants, reflecting the greater thermal demands of the V8 engine.
• The intercooler circuit on the GT 63 4MATIC+ and GT 63 S 4MATIC+ holds 6.4 liters, notably larger than the 4-liter intercooler capacity specified for the GT 43 and GT 53 variants.
• The AMG GT 63 S E Performance 4MATIC+ (290.679) introduces a third distinct cooling circuit dedicated to the electric motor, with a capacity of 10.7 liters, in addition to the main engine and intercooler circuits.
• On the GT 63 S E Performance 4MATIC+, the main engine cooling system capacity is 14.3 liters, which sits between the 14-liter figure of the six-cylinder variants and the 15.3-liter figure of the standard V8 GT 63 variants.
• The intercooler circuit on the GT 63 S E Performance 4MATIC+ holds 5.6 liters, a value between the 4-liter capacity of the six-cylinder models and the 6.4-liter capacity of the non-hybrid V8 GT 63 variants.
• A 120-month interval equals a 10-year service life for the coolant, which is consistent with modern long-life coolant formulations designed to maintain corrosion inhibitor effectiveness over extended periods.
• The electric motor cooling circuit on the GT 63 S E Performance 4MATIC+ at 10.7 liters represents the largest single auxiliary cooling circuit across all X290 variants listed, underscoring the thermal management requirements of the hybrid drivetrain.
