The presence of oil in the expansion ship is not very frightening. Usually, a driver learns this problem when the amount of antifreeze occurs in the liquid cooling system. So, let’s see what are the main signs, the causes and ways in which oil can damage this ship.

Seed indicating the presence of oil in the expansion ship:

• The appearance on the neck of the tank of an emulsion (resulting from the combination of oil with antifreeze)
• The presence of an oil film floating on the surface of the antifreeze. Usually the film has a dark shade and reflects the rays of light in different colors (diffraction effect);
• Change of the color of the antifreeze and the consistency of the cooling liquid. The antifreeze is a light blue, yellow, red or green liquid – all light colors.
• Unpleasant smell in the expansion vase: the antifreeze does not have a prominent smell, at most a weak and sweet smell. If the oil has entered the antifreeze, it is very likely that the smell becomes strong (a burnt smell) and pungent.
• The cooling liquid will feel oily to the touch. The antifreeze will never be oily in its natural state.
• Frequent engine of the engine. Due to the fact that the oil reduces the performance of the antifreeze, the latter is no longer able to cool the engine naturally. This also leads to reducing the antifreeze cooling point. For this reason, most specialists consider at this point that the antifreeze has diluted and taken under the coverage of the radiator or under the coverage of the expansion ship of the cooling system. In summer, when it is already hot, the phenomenon becomes much more visible. In addition, the overheated engine will be more easily observed its irregular operation, which will surely think.
• On the walls of the expansion tank of the cooling system are visible oil stains;
• On the lid of the radiator and the expansion vase you can see an emulsion deposit (mixture of antifreeze oil).
• With the increase in engine speed, in the expansion ship there are visible air bubbles that come out of the liquid.

After notifying the above signs, the conclusion is clear and without doubt: there is oil in the antifreeze!

How to test the presence of oil in the expansion ship?

In the situation in which you noticed some of the signs above, but you are not sure that they are really oil in the antifreeze, so you can test the hypothesis as follows:

Take a clean and dry towel that will sink into the expansion ship. The process will be quick, as the substance can assume. Then remove and burn.

In the situation in which there is oil, it will burn. If the solution does not shoot, then it is only antifreeze (why? Because the antifreeze does not burn)

The fact that these two liquids have come to combine means that the estate has surrendered and the entire point system must be controlled. Therefore, the delay of repairs can lead to clogging of the radiator, overheating and engine defect, as well as other unfortunate consequences.

What are the defects of the oil entry into the antifreeze?

To be easier to follow, we offer this table with symptoms and ways in which you can check the defect:

Causes of penetration of the oil in antifreeze

There are several causes of oil penetration in the antifreeze. Therefore, see the list from the rarer to the most common:

• Gasket of the Arrsa newspaper
• Garning wear or defect The heat exchanger (oil radiator)
• Crack in the cylinder coating (especially outside)

Methods of eliminating the causes that lead to the penetration of oil into the antifreeze:

Replacement of the gasket with a new one, the correct tightening of the pair screws using a dynamometric key

Sleep the head of the block using special cars, existing inside an automotive service

You can try to glue the heat exchanger, but this is not always possible and the piece will have to be changed with a new one

Clean the surface with a grinding roll, weaving, sealing with epoxy pasta. In the final phase, the surface was built with cast iron bars. In the worst case, a complete replacement of the cylinder block will solve the problem.

The consequences of the penetration of the oil in antifreeze

Most beginner drivers are interested in the question if it is possible to drive when the oil entered the antifreeze. In this case, it all depends on how much oil has entered the cooling liquid.

In the ideal case in which a small amount of oil in the antifreeze has penetrated, it is necessary to contact a seminar or a service to remedy the problem as quickly as possible. Only in the case of a small amount of oil can you travel a small distance by car (possibly even to the service).

It should be understood that the oil not only reduces the performance of the antifreeze, but damages the entire cooling system.

Below has the entrance of oil into the antifreeze:

• Seniorman frequent of the engine
• Clog the elements in the cooling system
• Damage to the elements of the cooling system
• The wear wear of the engine

If the oil enters the antifreeze but also the antifreeze in the oil, the engine can be partially or completely defective, drastically lowering its level of lubrication.

In these situations it is better to immediately start the repair work to minimize the negative impact of the lubricant – not only on the cooling system, but also for a negative effect on the car engine as a whole.

Therefore, if you come from Brasov or the environment, we invite you to make a Online programming At our service, where you can be sure that your car is in the hands of professionals.

Conclusion

It is possible to use an oil car in the cooling system only in the most extreme cases, for example, to reach an automotive service. The repair works must be performed as soon as possible, with the identification of the cause and its elimination.

The use of a vehicle with long -term oil and antifreeze mixture leads to defects that require very complex and expensive repairs.
