Mercedes-Benz G-Class, W465 (EU)

Coolant capacity & service interval

Mercedes-Benz G-Class, W465 (EU) models utilize coolant with a capacity of 20 liters. Service intervals require changes every 200000 km or 120 months. The data covers 2 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

TypeSpecifications
G 450 d, 465.310 (2024- )
  • Use: Normal
  • Capacity 20 liter
  • Change 200000 km/ 120 months
G 500, 465.210 (2024- )
  • Use: Normal
  • Capacity 20 liter
  • Change 200000 km/ 120 months

Additional Notes

  • Both the G 450 d (465.310) and G 500 (465.210) share an identical cooling system capacity of 20 liters, a figure that reflects a full system fill rather than a partial top-up or overflow reservoir volume alone.
  • The Mercedes-Benz G-Class W465 (EU) coolant change interval is rated at 200,000 km or 120 months, whichever comes first, under normal use conditions.
  • A 120-month coolant service interval translates to a 10-year replacement cycle, which is consistent with modern long-life coolant formulations designed to maintain corrosion inhibitor effectiveness over extended periods.
  • The normal use condition tied to the 200,000 km / 120-month interval means the specification applies to standard operating environments, without adjustment for more demanding driving cycles.
  • The G 450 d carries a diesel powertrain designation, while the G 500 is petrol-powered, yet both share the same 20-liter cooling system capacity and identical service interval, indicating a common cooling architecture across the two engine variants in the W465 platform.
