The weight of the G4CS engine is 159.7 kg (excluding attachments). The engine number G4CS is located on the cylinder block. The most well-known issue with the engine is the low lifespan of the timing belts and balancers. Due to the vibration of the balance shafts, the supports of the power unit quickly deteriorate. The use of inexpensive oils has a significant impact on the lifespan of the hydraulic lifters. On high mileage, the exhaust manifold may crack, but it can usually be welded. Additionally, floating RPMs are often encountered due to throttle or MAF contamination.
