The 1.3-liter 16-valve Suzuki G15A engine was produced in Japan from 1991 to 2002 and was installed on the second and third generation of the Cultus models popular in the local market. Then this power unit was sent to third world countries, where it is still being assembled.

Disadvantages of the Suzuki G15A engine
- This is a simple and reliable motor, but its aluminum block and cylinder head are afraid of overheating;
- With regular overheating, cracks appear very quickly in the cooling jacket;
- The timing belt often bursts before the regulations, but it’s good that the valves do not bend here;
- After 150,000 km, valve stem seals wear out and lubricant consumption appears;
- There are no hydraulic lifters here and every 30,000 km you will have to adjust the valve clearances.
