BMW 3 series Gran Turismo, F34 (USA)
Coolant capacity & service interval
BMW 3 series Gran Turismo, F34 (USA) coolant capacity ranges from 3.5 to 10.5 liters depending on the cooling system type. The data covers three configurations. Capacities include 7.6 liters, 8.1 to 9.3 liters for high temperature cooling systems, 3.6 liters for low temperature cooling systems, and 9.3 to 10.5 liters for high temperature cooling systems with another low temperature system capacity of 3.5 liters.

Additional Notes
- The BMW 3 Series Gran Turismo F34 (USA) coolant specifications cover three engine configurations across the 2015-2019 model years, each with distinct cooling system capacities.
- The 328i Gran Turismo with the N26 engine, produced for 2015-2016, carries a single cooling system capacity of 7.6 liters, reflecting a conventional single-circuit cooling architecture.
- The 330i Gran Turismo xDrive and 340i Gran Turismo xDrive, both spanning 2016-2019, are specified with two separate cooling circuits: a high temperature cooling system and a low temperature cooling system, indicating a dual-circuit thermal management layout.
- For the 330i Gran Turismo xDrive, the high temperature cooling system holds 8.1-9.3 liters, while the low temperature cooling system holds 3.6 liters, with both figures applying as of production date 01-08-2018.
- The 340i Gran Turismo xDrive carries the largest high temperature cooling system capacity in the lineup, ranging from 9.3 to 10.5 liters, alongside a low temperature circuit of 3.5 liters, also applicable as of production date 01-08-2018.
- The capacity ranges listed for the high temperature circuits on both the 330i and 340i Gran Turismo xDrive models reflect variation within the configuration rather than a single fixed fill volume, meaning the actual service fill amount falls within the stated range depending on the specific build.
- All three configurations are specified under normal use conditions, meaning the capacities listed apply to standard operating environments rather than severe-duty or first-change scenarios.
- The production date qualifier of 01-08-2018 on the 330i and 340i Gran Turismo xDrive rows indicates the dual-circuit specifications are tied to vehicles produced from that date onward within the 2016-2019 production span.
