The weight of the AJ34S engine according to the catalog is 190 kg. The engine number AJ34S can be found on the cylinder block. The aluminum motor is very susceptible to overheating, so keep the radiator clean. VVT phase regulators have a limited lifespan, sometimes less than 100,000 km. The VKG valve quickly gets clogged, resulting in high oil consumption. Periodic cleaning is required for the throttle body and fuel injectors. On high mileage, coolant leaks often occur due to burst hoses.
