The weight of the AJ28 engine according to the catalog is 180 kg. The engine number AJ28 can be found on the cylinder block. The early motors in this series had a nikasil coating, but the version AJ28 with cast iron liners has a shorter lifespan due to its timing chain, sometimes lasting less than 100,000 km. The engine control unit (ECU) often malfunctions here, and it is better to immediately update the firmware. This engine is sensitive to overheating, so monitor the condition of the radiators, water pumps, and thermostats. The remaining problems are related to sensor glitches and leaks of lubricant or coolant.
