Mercedes-Benz G-Class, W463B (EU)

Additional Notes

• The Mercedes-Benz G-Class W463B (EU) coolant service interval is uniform across all listed variants at 200,000 km or 120 months under normal use conditions, whichever comes first.
• The 13-liter main cooling system capacity listed for the G 350 d, G 400 d, and G 500 represents the fill range between the minimum and maximum marks on the reservoir, rather than a total system volume figure.
• The G 63 AMG carries a slightly larger main cooling system capacity of 13.7 liters between min and max, compared to the 13-liter figure shared by the three other variants.
• Each variant in the W463B lineup carries a separate intercooler circuit with its own coolant capacity, meaning the total cooling fluid volume per vehicle spans two distinct circuits.
• The G 350 d and G 400 d diesel variants share an identical intercooler coolant capacity of 4.6 liters, as does the G 500 petrol variant.
• The G 63 AMG intercooler circuit holds 6.6 liters, which is notably larger than the 4.6-liter intercooler capacity of the other three variants, reflecting the greater thermal demands of the AMG-tuned 4.0-liter biturbo V8 engine.
• The intercooler coolant circuits across all variants share the same 200,000 km or 120-month change interval applied to the main cooling system, with no differentiated schedule between the two circuits.
