The weight of the AR32310 engine according to the catalog is 170 kg. The engine number AR32310 is located at the junction of the block and the gearbox. The unit is characterized by rapid wear of the cylinder walls and subsequent oil consumption. Due to the wedging of the hydraulic compensators, the camshafts lobes wear out quickly. Sensor malfunctions, especially the DMRV and crankshaft position, are causing a lot of problems. Keep an eye on the condition of the balancer belt, as if it breaks, it can get caught in the timing belt. Weak points of the engine include the oil pump, phase regulator, and VLIM system in the intake.
