On a hot day, and in winter, especially when the car moves in traffic jams - the car often suffers from overheating. And if the driver does not pay attention to the engine overheating problem, believing that the cause is a high outdoor temperature, a trouble may occur with the car. The car engine may fail due to overheating, but the antifreeze leak can be caused by this. Based on this, we advise you to deal with the problem of engine overheating at the initial stage.

Signs of cooling system malfunction

Antifreeze is coolantTo protect the engine from overheating, thereby increase the efficiency of the engine and save fuel.

The efficient operation of the engine, occurs at a certain temperature segment, and when the cooling system begins to malfunction, the engine increases the temperature and the driver can observe the following:

-par is knocked out of the hood;

- White smoke is visible from the muffler;

-The salon does not heat the stove;

- on dashboard, engine overheating signal;

-Terometer issues maximum value;

-New spots on the site of the car parking.

The driver can see only one sign, since the remaining signs of overheating may appear later.

But in any case, with such a scenario, the car needs to stop and make a thorough visual inspection.

Where the coolant is dried

If the driver, after stopping the car, looked under the hood, did not find antifreeze in an expansion tank, do not immediately rush into panic, you need to understand why the volume has decreased coolant And where could the cooling fluid might go.

There may be several reasons:

- low temperatures, coolant is capable of decreasing in volume, so it is necessary to add antifreeze and trace it in the future;

-Antifriz can flow through the slots and cracks of the expansion tank or cover, so visually inspect the tank and if everything says that a tank or a cracker cover, it is necessary to replace the expansion tank or the tank cover;

- the problem is possible in damage to the hoses, tubes, or the depressurization of the compounds occurred, leakage is possible from under the laying of the thermostat;

- perhaps a breakdown of heating radiator;

-Ard failure of the car cooling radiator;

-Ard failure of the pump is accompanied by leakage of antifreeze;

- perhaps, antifreeze got into engine oil (the worst version of the development of events);

Eliminate antifreeze leakage problems

If you analyze the reasons for reducing the volume of antifreeze in your car and install a specific malfunction - you can decide how to cope with this problem, remove it yourself or contact professionals to the service center.

In each case, it is necessary to figure out:

- negative outdoor air temperature. When coldly occurs, the coolant is capable of decreasing in the volume and the driver will only need to add antifreeze into the expansion tank. At the same time, it is impossible to dissolve antifreeze with water, otherwise the water will freeze and various breakdowns may occur, up to the engine breakdown;

- perhaps a crack in the tank. If a crack appeared in a tank or lid - the coolant will quickly evaporate, and although you will pour antifreeze - this will not solve the problem. In this case, you need to replace the tank or cover.

Damage in cooling system connections

When suspected damage in the connections system - put a piece of cardboard over the night.

If in the junction system leakage, on cardboard, in the morning, detect stains. In this case, by adjusting high-quality workplace lighting, carry out a visual inspection of all hoses and tubes, connecting places with a radiator, inspect the thermostat gaskets.

The easiest way to do the inspection of rubber pipes, cracks may appear on rubber due to the rapid aging of the material, under the influence of high temperatures.

Nozzles need to be examined on all sides, for this you can use a mirror or check the quality of the rubber nozzle to the touch. If necessary, replace rubber pipes.

Since the above operation is performed with direct contact with the car, starting to work, give the car to cool so as not to get thermal burner.

If, after inspection, you did not find a leak in rubber nozzles, you need to check the quality of the connection tightening (clamps), try tightening the nuts of the clamps.

If you checked all connections and did not find leaks - proceed to check the pump. About the malfunction of the pump you can notify unpleasant screech, when the car starts, then the screech will stop.

Antifreeze can flow due to wear of the pox seal.

In this case, you will notice traces of splashing, to the surrounding details, around the axis of the pump rotation.

This problem is more complicated, the pump can be changed independently, or consult professionals.

Leak antifreeze in cooling radiator

Eliminate the flow or change the car cooling radiator is better to produce in specialized car repair centers.

Antifreeze leak through heating radiator

If the problem with the heating radiator, in this case, there will be constant fogging of the windshield, and near the chair, under the legs of the front passenger of the antifreeze. Urgently repair.

Radiator repair is better to entrust professional workers.

If antifreeze enters the engine oil

The cooling fluid can get into the oil channels if there are cracks in the metal of the cylinder block or the blocking of the block head came out.

In this case, antifreeze and oil are mixed, a foaming fluid is formed, which has low lubricating properties, the result is increased friction and the engine can jam.

Such a defect happens most often by the car, which has a mileage of more than 100,000 km.

Due to large loads, there is a breakdown of the cylinder block head.

If the gasket is made of metal, this laying is very reliable, and if the gasket is made of a paronite - it can quickly fail. The driver detects this malfunction when inspecting the detection of the Motor Oil level.

If traces of white foam are present on the dipstick, the antifreeze is mixed with oil.

In addition, there will also be white spots on the ignition candles, the exhaust pipe will go white smoke, and in the cabin there will be a lightweight, sweet smell of antifreeze.

This malfunction can solve only maintenance station workers.
