The weight of the 4A31 engine according to the catalog is 105 kg. The engine number 4A31 is located on the right, below the exhaust. The aluminum head is sensitive to overheating and easily cracks if the bolts are tightened too much. The engine mounts wear out quite quickly and the unit starts to vibrate. The timing belt is designed for a mileage of 90,000 km, but in case of valve failure, it always bends. It is necessary to adjust the valve clearances approximately every 50,000 km. By 90,000 km, the rings or valve stem seals are usually worn out and oil consumption begins.
