GAC GS3
Brake fluid capacity & service interval
GAC GS3 uses brake fluid with a capacity range of 0,7 to 0,8 liters. Service intervals require a change every 24 months. The data covers 5 configurations.
The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes
- The GAC GS3 hydraulic brake system holds 0.8 liters of brake fluid across both the 1.3T and 1.5 naturally aspirated variants covering the 2017-2022 model years.
- The 0.8-liter figure represents a service fill capacity, meaning the amount of fluid the hydraulic brake circuit holds during normal operating conditions rather than a dry or overhaul fill.
- Three configurations introduced from 2022 onward, the GS3 EMZOOM 1.5T, the GS3 Power 1.5T at 110 kW, and the GS3 Power 1.5T at 117 kW, each carry a reduced hydraulic brake system capacity of 0.7 liters compared to the earlier 0.8-liter specification.
- The 0.1-liter difference between the 2017-2022 variants and the 2022-onward variants reflects a variation in brake circuit volume, which can result from differences in caliper design, master cylinder sizing, or brake line routing between generations.
- All five configurations share an identical change interval of 24 months under normal use conditions, meaning the fluid replacement schedule is not differentiated by engine output or variant type.
- A 24-month brake fluid change interval is consistent with the hygroscopic nature of brake fluid, which absorbs moisture from the atmosphere over time and lowers the fluid's boiling point, reducing braking effectiveness under heat.
- The two GS3 Power 1.5T variants from 2022 onward differ only in power output, at 110 kW and 117 kW respectively, yet both share the same 0.7-liter brake fluid capacity and 24-month service interval.
