Where does antifreeze go?
Where does antifreeze go?
Faults in the cooling system mayrather serious problems with the car, so, barely noticing that the arrow of the thermometer crawled up, the engine overheating warning light came on, steam appeared from under the hood or the white smoke from the muffler came out, the heater suddenly started to blow slightly cold air, stop the car and turn off the engine. These signs may indicate that you have a lack of antifreeze.

The first reason is the breakdown of the head of the blockcylinders. It is most likely for cars with a mileage of more than 100,000 km. The cylinder head gasket is under severe load. If the gasket is made of metal, the temperature and compression effects only slightly affect it, but here the paronite gaskets are much more susceptible to destruction. Most often, the breakdown of the head of the block occurs when the engine overheats.

The manifestation of the breakdown of the SGB: 1) Antifreeze bulges out of the expansion tank, which indicates that the gases at the time of compression in the engine cylinders under pressure penetrate into the cooling jacket, creating there an excess pressure. 2) Antifreeze goes inside the cylinder (s), rushing into the exhaust system together with the exhaust gases. There is white smoke, as well as a sweetish smell from the muffler. 3) Through a defect in the PHB, the coolant enters the crankcase of the engine, mixing with the engine oil and forming an emulsion of white color. 4) The antifreeze goes out because of the loose fit of the cylinder head to the block.

In any of the above cases, you should immediately call the service station to repair the malfunction. So you will avoid more serious problems with the engine.

Mechanical wear of the components and mechanisms of the systemCooling can also lead to a lack of coolant. Antifreeze can get to where it should not be in many places. For example, through the damaged radiator of the cooling system, the radiator pipes, the radiator drain box seal, the stuffing box of the water pump and other places. There are many options, and defects of this kind are determined visually during the passage of maintenance.

If there is a suspicion of a latent leak of antifreeze, the system of cooling is pressurized. Having identified the source of the leak, the defect can be eliminated by replacing or repairing the defective unit.
