The gauge of pressure of oil on models М10 will screw in the left back part of a head of cylinders, on models М20 – in the block of cylinders under the oil filter, on М40 – in a back part of the case of the oil filter. For pressure measurement turn out the gauge and screw the believed manometre.
The prevention At major repairs of the engine all hoses of system of cooling, drive belts, the thermostat, the oil pump and the pump of a cooling liquid are subject to obligatory replacement.
