Disadvantages of the Suzuki M18A engine

  • Most often, car owners with such an engine complain about high lubricant consumption.
  • The motor overheats quite quickly and at the same time often breaks through the cylinder head gasket.
  • The reason for floating engine speeds is usually a dirty throttle or EGR valve.
  • Other weaknesses of the unit include short-lived supports and problematic sensors.
  • At high mileage, liners can sag and antifreeze will mix with oil.
