The dry weight of the G4HD engine according to the catalog is 84 kg. The engine number G4HD is located on the right at the junction with the gearbox. This engine does not have any structural problems, although it cannot be called long-lasting. The most important thing is to keep the radiators clean, as overheating can immediately lead to cylinder head damage. Often, the engine speed fluctuates due to throttle and idle control valve contamination. Spark plugs here have a very short lifespan, and the insulation of the wires quickly deteriorates. After 250 thousand km, a major overhaul is often required, and there are repair dimensions available.
