The auto expert listed the risks of temperature fluctuations for the car

Sudden temperature changes are harmful to various components and assemblies of the car. Yulia Trushkova, Rolf's Director of Service, told about this on April 28. First of all, the battery suffers — when the temperature drops, the chemical processes inside the battery slow down.

"And if it's minus at night and plus again during the day, the plates begin to collapse faster. This is especially critical for old batteries: they can give up at any moment," Rossiyskaya Gazeta quoted Trushkova as saying.

The cooling system also suffers due to sudden temperature fluctuations. Antifreeze is designed to operate in a certain temperature range. With sudden fluctuations, microcracks appear in the pipes, the radiator may break through or the lid of the expansion tank may burst, the expert explained.

In addition, in such conditions, the oil thickens, then abruptly liquefies. The oil seals of the engine, gearbox and axle shafts are especially sensitive to sudden temperature fluctuations — the rubber loses elasticity, microcracks appear, and oil begins to leak. Electronics start to malfunction due to condensation and aging connectors (contacts "sweat", close, and phantom errors appear). Finally, when it gets cold, tire pressure drops, which leads to fuel overspending and increased rubber wear, the expert added.

When to expect the mass appearance of "Chinese" with mileage on the car market

On April 18, expert Alexey Abrameytsev said that buying summer car tires on the secondary market can lead to serious problems during operation. Such tires may have hidden damages and flaws, although visually they may be without defects or even resemble new ones.

On April 11, Roman Sokuev, head of the Sintec Lubricants Technical expertise center, said that due to the operation of the start-stop system, additional loads on the engine and engine oil arise, which requires special attention from the car owner.
