Disadvantages of the Suzuki G13B engine

  • The main thing is not to allow the motor to overheat, then it will serve for a long time and without problems;
  • Overheating cracks the cooling jacket of the aluminum block, and sometimes the cylinder head;
  • Also, the exhaust manifold often bursts, but it is quite possible to brew it;
  • Quite a few problems here are due to the vagaries of an outdated ignition system;
  • It does not have hydraulic lifters and the valve clearance needs to be adjusted every 30,000 km.
