In gasoline engines N42 The resource of the chain and tensioner is about 200 thousand km. Engines of the N series manufacturer allow oil consumption to 750 grams per 1000 km. Six-cylinder gasoline engines are extremely reliable with timely replacing oil and filters (oil, fuel, air), as well as supporting the cooling system in fully working condition, because These engines do not like overheating. The chain resource with the tensioner on six-cylinder gasoline engines is about 400 thousand km. In the case of untimely replacement of the worn circuit, it is possible and, as a result, expensive repair (cost of the chain and tensioner: 5300 rubles and 3800 rubles; work on the replacement of the chain with a tensioner of 55,000 rubles, at the cost of the norm-hour 3200 rubles). In diesel engines M47 and M57 with the Common Rail injection system in the intake manifold there are vortex flaps, the resource of which is 120 - 150 thousand km., the failure of the vortex dampers leads either to the need for expensive repair, or to the replacement of the engine. Bibeedia recommends propagatively remove vortex flaps from the intake manifold in M47 and M57 engines to avoid possible engine damage (in case of failure, they are found in cylinders). Bibipeedia recommends on vehicles with diesel engines in mandatory every 10 thousand km. Change the fuel filter, as well as use only high-quality fuel, as the use of low-quality fuels leads to damage to electronic nozzles and fuel equipment. |
