In summer, a car suffers not only while driving but also while parked. While the driver relaxes on the beach or works in the office, the body heats up to 70 °C, the plastic in the cabin becomes softer, and the air inside turns into a real sauna. One hot day rarely ends with serious consequences, but if the car sits under the scorching sun for weeks, problems begin to accumulate. The good news is that most of them can be avoided.
The main enemy is not the high air temperature, but direct sunlight. In the sun, a car's body heats up much more than the surrounding environment, and the paintwork constantly experiences temperature fluctuations.
Heat can damage:
If the body has not been protected with wax or ceramic coating for a long time, ultraviolet light gradually reduces color saturation. This is especially noticeable on red, blue, and black cars. The sun does not pick favorites—it is equally merciless to both a budget sedan and an expensive crossover.
The car's cabin heats up faster than the body. Within an hour, the temperature under the windshield can be significantly higher than the air temperature.
To reduce heating, it's worth following a few simple rules:
Even a simple sunshade can noticeably reduce the temperature of the dashboard and steering wheel.
If the car will not be used for several weeks, it's better to prepare for storage in advance.
Before a long parking period, it is recommended to:
If possible, it's better to use a breathable protective cover. However, covering a dirty car with a tight tarpaulin is not advisable: underneath, dust turns into an abrasive that, at the slightest wind, begins to polish the paint in a rather peculiar way.
Many believe that the battery only discharges in winter. In practice, heat also shortens its lifespan.
High temperature accelerates chemical processes inside the battery, increases self-discharge, and promotes electrolyte evaporation. If the car sits idle for a long time while the security system remains on standby, the charge gradually decreases.
This is especially noticeable in cars with alarms equipped with tilt and shock sensors. In summer, the body expands and contracts more, and there are more vibrations from thunderstorms, wind, and passing traffic. The electronics wake up more often, periodically activating sensors and consuming energy. This creates a peculiar paradox: in winter, the battery spends energy on cold engine starts, and in summer—on patiently waiting for its owner.
High temperature is dangerous not only for the car but also for the items inside it.
In hot weather, it's better to take out of the cabin and trunk:
When strongly heated, the pressure inside aerosols and lighters rises sharply. At best, they will lose their seal; at worst, they may rupture, damaging the car's interior. Such a firework display is definitely not on the list of summer entertainment.
It is impossible to fully protect a car from heat, but it is quite realistic to significantly reduce its consequences.
It is enough to follow a few rules:
A few minutes of preparation cost much less than restoring a faded interior, replacing a battery, or repainting the body. The summer sun does not forgive mistakes, but it willingly rewards careless owners with them.
