Chang'an CX20
Brake fluid capacity & service interval
The Chang'an CX20 uses brake fluid with a capacity range of 0.47-0.53 liter. The data covers 2 configurations.
The configuration chart below lists fill volumes and service intervals for each engine and trim variant.
| Type | Specifications |
|---|---|
| CX20 1.4, JL473Q1 (2013-2016) |
|
| CX20 1.3, JL474Q (2010-2012) |

Additional Notes
- The Chang'an CX20 1.3 with the JL474Q engine, covering 2010-2012, carries a fixed brake fluid capacity of 0.5 liter for the hydraulic brake and clutch system under normal use conditions.
- The 1.4 JL473Q1 variant, spanning 2013-2016, lists a capacity range of 0.47-0.53 liter rather than a single fixed value, reflecting an allowable tolerance band within the hydraulic brake and clutch system fill.
- A capacity range such as 0.47-0.53 liter typically accounts for minor variation in reservoir level between the minimum and maximum marks, meaning an acceptable fill falls anywhere within that window rather than at one precise point.
- Both engine variants share the same system scope, covering the hydraulic brake and clutch circuit together, which means a single fluid reservoir serves both functions across the CX20 lineup.
- The shift from a single fixed value in the 1.3 to a tolerance range in the 1.4 represents a measurable difference in how capacity is expressed between the two engine generations of the CX20.
