New cars are becoming more and more expensive and remain an unattainable dream for many car owners. They are forced to “wear out” obsolete vehicles, faced with all
Practice shows that antifreeze only attracts the attention of most motorists when the engine cooling system fails or threatens to fail. That is, when it leaks somewhere or when the engine begins to show obvious signs of overheating. The problem is that it is sometimes difficult to understand the reason for this. Especially in the summer, when the heat, unexpectedly for the car owner, can even boil the engine, which did not indicate the presence of problems with cooling.
This occurs when the increased outboard temperature shifts the existing balance of factors that ensure the balance of the “engine cooling system” to “the red zone”. This means that at some point the efficiency of the latter becomes insufficient and can no longer cope with the excess heat supplied by the engine. And its (efficiency) is determined by two main factors: the ability of the radiator to transfer heat to the surrounding air and the performance of the pump. Both parameters are most directly affected by the “freshness” of antifreeze.
The coolant that has not changed for a long time, among other things, no longer protects the internal surfaces of the pipes in the engine casing from corrosion. Which leads to the appearance of a suspension of rust particles in it. Sometimes you can at least look around the open neck of the expansion tank and try to see hints of red haze there. The eye does not see it, but it is there. And this dirt clogs the tubes in the radiator, greatly impairing their throughput, and also accelerates the wear of the moving parts of the water pump, bringing death closer.
An imperceptible decrease in the initial “conditions” of the radiator and coolant pump due to antifreeze problems increases the likelihood of the engine overheating in the summer, when the system is operating under high load. Therefore, experienced car owners try not to postpone the replacement of antifreeze if this scheduled procedure falls on a later date. In such a situation, it is better not to be greedy and postpone the operation – we change the coolant in the summer! We also do this with a mandatory flushing of the system: those who want to save on maintenance are punished with an exam in the summer heat with expensive repairs.
