The weight of the Z28NET engine according to the catalog is 215 kg. The engine number Z28NET is located at the junction of the block and the gearbox. Chain stretching in the timing drive is done with three plate chains from Morse with a modest resource, often they stretch up to 100,000 km, and their replacement is complex and quite expensive. Engine overheating: This unit quickly overheats, so keep an eye on the condition of the cooling system, moreover, the thermostat here is not very reliable and coolant leaks often occur. Air leakage: The thin-walled air duct that goes from the air filter to the intake manifold wears out quickly. When unaccounted for air enters, the engine starts to run unstable. Turbocharger: The turbine itself is reliable and the problems are caused only by the bypass membrane and the bypass valve. Their failure results in insufficient or excessive boost pressure. Other drawbacks: The weak points of this engine also include the electronic engine control unit, fuel pump, oil pressure sensor, power steering pump, and electric vacuum brake booster.
