What are the dangers of sudden temperature changes in winter for a car?
Winter is still in full swing, and residents of the European part of Russia are already tired of the frequent and sharp temperature changes characteristic of the current cold season: 30 degrees of frost in one day can give way to thaw and vice versa. But cars also have to bear the brunt of such tricks of nature…

Warming usually occurs due to the arrival of wet cyclones. And then the water-saturated air is cooled by the next Arctic anticyclone. Which causes precipitation. The problem is that these types of climate mechanisms not only work outside the car, but also in the fuel tank. This leads to the appearance of water in the fuel.

It is heavier than petroleum products and therefore accumulates at the bottom of the tank. Where it can get into the fuel pump and freeze during the next cold snap, leaving the car parked until the next thaw. The development of events in this scenario can be prevented by preventively pouring a liter of pure ethyl or isopropyl alcohol into the gas tank every month.

Wash your car in cold weather? “Not really!” – many car owners will answer. And they will be wrong worldwide. Although this approach eliminates the risk of the doors and tank flap freezing after a visit to a car wash. But in fact, a periodic “bath” for a car during frequent “weather jumps” from severe frost to relative warmth is not a whim, but an enforced necessity.

Indeed, temperature changes aggravate problems with the bodywork paint, facilitating the penetration of aggressive road chemicals into the “micro wounds”. The only way to reduce the negative effect of its impact is to wash your car regularly to remove salt and reagents. Without taking into account the temperature outside the window.

Temperature changes also contribute to the accelerated aging of all types of rubber equipment. Various seals, oil seals and hoses in particular are affected. This can be especially noticeable on older machines. Because all these essential little things have already lost quite a bit of their original elasticity during their long lifespan. And then, after the thaw, there was a strong and sharp cold wave. Well, how can you not get into trouble here?!

It is during the bitter cold, which has replaced the ghostly warming of winter, that oil from the engine often begins to flow through the gaskets and seals. Or, for example, a cooling system hose ruptures, causing the entire engine compartment to flood with antifreeze.

As a rule, car electricians are also “not happy” with temperature fluctuations. First of all, they every time check the elasticity and resistance to tearing of the insulation of all kinds of wires for suitability. Well, the ubiquitous sweating is there. No electricity benefits from contact with moisture. Therefore, do not be surprised by sudden “malfunctions” of certain electronics or electrical systems in the car after a sharp warm-up or cold.

Please note that it is impossible to protect your car from all the negative consequences of temperature changes in winter. Therefore, at such moments you should pay more attention to the “health” of the car and immediately respond to the slightest symptoms of possible defects. It’s better to be on the safe side than end up with serious repairs later.
