Types of cooling system contamination
One of the reasons for the overheating of the power unit is the clogging of the car's cooling system, which occurs during its operation. To prevent the system from clogging, it is necessary to periodically flush it. Find more here: oil in anti freeze
Foreign substances that accumulate over time do not allow the coolant to circulate normally, cool down and heat up, which is why it cannot fully cope with the functions assigned to it. Such substances are:
- scale - formed if non-distilled water is used as a coolant;
- pollution - sand, dust, residues of engine oil , sealant;
- the result of aging of antifreeze - over time it gradually decomposes, leaving a residue.
How to flush the cooling system and radiator from harmful deposits?
To clean the cooling system, you can turn to professionals who have the necessary tools and skills, but this procedure is not so difficult, so it is quite possible to flush the cooling system yourself.
The cooling system is flushed using water, acidified water or special preparations - the choice depends on the degree of pollution. If the system is relatively clean, then ordinary distilled or boiled water is enough, which is poured inside, after which the engine is allowed to idle for 10-15 minutes. Then the water is drained and the procedure is repeated until the liquid is clear when draining.
