Disadvantages of the Suzuki G10A engine

  • If this power unit is not overheated, then it lasts a long time and without any problems.
  • Overheating leads to cracks in the cylinder head or cooling jacket of the aluminum block.
  • At high mileage, oil consumption is often encountered due to wear of cast-iron liners.
  • A lot of problems for owners are thrown by the whims of an outdated ignition system.
  • Most versions do not have hydraulic lifters and the valve clearance must be adjusted.
