The 1.25-liter Chevrolet B12D2 or LL0 engine has been produced at the concern’s factory since 2012 and is installed on the third generation of the popular Spark model and the similar Ravon R2.

Disadvantages of the B12D1 engine
- This is a simple and reliable power unit without any pronounced weaknesses.
- On specialized forums, only noises under the hood and the appearance of the Check Engine in winter are discussed.
- Saving on lubrication greatly reduces the resource of hydraulic lifters, sometimes up to 50,000 km.
- It is also important to monitor the condition of the timing chain, since when it jumps, the valves bend.
- The remaining problems are related to overheating or attachment failures.
