Engine Overview and Common Failures
The weight of the 6G73 engine according to the catalog is 195 kg. The engine number 6G73 is located at the junction of the engine and the gearbox. The GDi system. This distributed injection engine is not very demanding in terms of fuel quality, but many of these engines were equipped with a capricious direct injection system GDi, which can cause you a lot of problems. The fuel injection pump is especially prone to failure. In all other aspects, this is a reliable engine and owners regularly complain only about excessive oil consumption. At mileage over 200,000 km, oil control rings wear out or piston rings get stuck, resulting in oil consumption. The main thing is not to neglect the oil level, or else the bearings will spin. Another common issue is fluctuating engine speeds, which can be caused by a variety of reasons such as throttle body contamination, idle air control valve and injector malfunctions, broken wiring, burnt-out oxygen sensors, or incorrectly installed manifold after spark plug replacement. Despite the fact that the timing belt is thick and lasts longer than recommended, breaks still occur frequently. The cause can be clogging of the oil channel of the hydraulic tensioner or oil leakage from under the front engine cover, where the oil drips directly onto the belt. Other weaknesses of this engine include an unreliable ignition system, short-lived hydraulic lifters that can start ticking before reaching 100,000 km mileage, as well as weak gaskets and hoses, leading to frequent oil or coolant leaks.
