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.
