The weight of the 4A30 engine according to the catalog is 104 kg. The engine number 4A30 is located on the right, under the exhaust. The aluminum head of the block often cracks due to overheating or bolt overtightening. When there are strong vibrations, replacing one of its mounts usually helps. Some engine modifications are equipped with a turbocharger, which has a short service life. The valves need to be adjusted every 50,000 km, and the timing belt should be replaced every 90,000 km. After 100,000 km, oil consumption begins due to worn piston rings or valve seals.
