The weight of the GW 491QE engine according to the catalog is 126 kg. The GW 491QE engine number is located at the junction of the block and the cylinder head. Structurally, it is a reliable and durable motor, but its assembly quality is lacking. This unit is also very sensitive to overheating and can blow the cylinder head immediately. Air leaks and frequent failures in the ignition system are also troublesome. Sometimes there are cracks in the block between the 4th cylinder and the coolant channel. After 100,000 km mileage, oil consumption of up to 1 liter per 100 km often occurs.
