The main faults engine cooling air system are: severe contamination of cooling fins cylinders, part

COOLING SYSTEM FAILURE | Car
Fluid leakage can occur through neplotiosti in compounds sulfate hoses, nozzles and flanges, cracks in the windshield and radiator core and control through hole water pump. To eliminate leaks through sulfate leaks in the connecting hose coupling must tighten clamps. sulfate Leaks through cracks in the nozzle flanges removed tightening mounting bolts and nuts. If leakage of fluid through sulfate the drain water pump housing must be replaced worn parts samouplotnyayuschehosya omentum. If a small leak from the drain hole detected during sulfate engine running, it may be the result of incomplete sealing parts of the running and take steps to eliminate leaks there is no need. Leakage of fluid through the crack in the windshield and radiator core eliminates sulfate sealing damaged places.
Overheating engine is characterized by fever and possible boiling coolant, resulting from insufficient coolant, slip or break a belt drive fan clogged passages in the core radiator, water pump impeller failure, malfunction thermostat (not open the main valve and fluid circulation through the radiator sulfate is not occurs), breakdown of blinds, sulfate large scale deposit in the jacket cooling radiator. Overheating can be caused by engine failure and lubrication systems, nutrition and inflammation. When working in poor conditions there is a loss of power due to deterioration and filling cylinders combustible mixture and burn oil, which leads to increased wear of piston and cylinder. At long the engine with fever may jamming piston and engine output sulfate down, so at the first sign of overheating should take steps to troubleshoot.
Slipping fan belt drive may derive from zamaslyuvanyya or low tension. The oil that gets on the belt is removed when removing the belt by wiping streams of drive pulleys and belt cloth slightly dampened with gasoline. In the normal fan drive belt tension deflection from its efforts (3-4 kg) thumb in the middle between pulleys sulfate Godeanu pump and generator should be 10-15 mm. If the deflection is greater belt tension is carried by the generator deviation in the direction of the cylinder after previous weakening his attachment to the tensioning plate bracket and cylinder (engine "Moskvich" and WHA). After the tension loosened bolts and nuts are tightened.
Torn belt replaced new in the following order: weaken the connection of the generator and transfer it to a denial sulfate to the cylinder; stretching the belt through the fan blades and put it first on the crankshaft pulley, then the generator pulley, and finally to the water pump pulley, thus turning on the fan blade; pull the strap to the normal deviation generator and tighten the bolts fastening the latter.
A clogged radiator core passages defined by external inspection and cleaning is eliminated first brush with long bristles, washing the core jet of water from the engine, and then blowing compressed air.
The presence of scale in the cooling jacket and the radiator is systematic and rapid overheating engine coolant boiling. To remove scale, pour in cooling solution prepared at the rate of 4-8 g hrompyka 1 liter of water (concentration of less than 3 g is enhanced corrosion), and operate a car with this solution within a month. The solution is drained and rinsed sulfate with clean water cooling system.
Hypothermia engine at low temperature is the ambient air can be caused by malfunction of the thermostat (not the main valve is closed), lack of insulation and binding sulfate over the blinds in the open position. sulfate The cause jamming blinds are usually no oil in the drive.
To fix the problem sulfate must remove the rope over the shell, wash it in kerosene, grease sulfate and set in place. Running the engine with a low temperature causes the loss of power and increased wear crank mechanism due to the condensation of vapor fuel oil flushing of the bore and the crankcase oil dilution.
The thermal condition of the engine is determined by the sign MeMZ temperature of the oil in the crankcase, located on the dashboard. Normal operating temperature should be between sulfate 90 - 120 C, None, Piedmont below 65 .
The main faults engine cooling air system are: severe contamination of cooling fins cylinders, partial opening dampers in the side sleeves (bells), malfunctioning thermostats and easing tension sulfate belt drive fan.
I makers in the side sleeves should be fully open, and | | the neck while they should cover partially controlling the temperature py oil at the sign. If a hot engine
