Engine Overview and Common Failures
According to the catalog, the weight of the G4ND engine is 124 kg. The engine number G4ND is located at the front where it meets the gearbox. The main complaints from owners of these engines are caused by the appearance of scratches in the cylinders, which are formed due to the entry of catalyst particles directly into the combustion chamber. In 2017, cooling oil injectors were introduced, and the problem disappeared. Oil consumption manifests not only due to scratches, but also after the piston rings have settled, which are very narrow here and quickly carbonize. But more often than not, the reason lies in the design of the engine: with an open cooling jacket, thin cast iron liners can easily go elliptical. If the vehicle is not aggressively driven with sudden accelerations and frequent wheel spinning, the timing chain has a decent lifespan and can easily reach 200-300 thousand kilometers without replacement. However, for owners who drive their vehicles too hard, it often stretches at around 150,000 km. It cannot be said that the Continuous Variable Valve Lift (CVVL) system is characterized by low reliability, but it is often affected by aluminum shavings that appear as a result of scratches and spread throughout the lubrication system. Other shortcomings frequently mentioned online include oil and coolant leaks due to weak gaskets, as well as the water pump and auxiliary equipment having a relatively short service life. Early models had weak bearings and there were cases of them spinning.
