Extreme heat significantly impacts not just driver comfort but also the overall performance of a vehicle, particularly if summer driving precautions are overlooked. This was highlighted by Yegor Stepanov-Kim, a race car driver from the G-Drive SMP Racing program.
Stepanov-Kim advises against idling with the air conditioning on when stuck in traffic, especially if the car`s interior temperature is rising. Instead, he suggests airing out the vehicle by opening windows for a minute before switching on the AC to reduce the initial heat build-up. He also cautioned against overworking the climate control system, as this can quickly deplete its lifespan.
“Avoid parking your car directly under the sun,” Stepanov-Kim recommends. “If there`s no alternative, try to orient the front of the car towards any available shade and use a reflective sunshade for the windshield. The cabin temperature can easily exceed 40 degrees Celsius (104°F), which is detrimental to plastic components, wiring, and onboard electronics.”
The expert further emphasized the importance of monitoring engine coolant temperature when driving on highways. If the temperature exceeds 90-105°C (194-221°F) and the cooling fan runs continuously, it`s crucial to pull over immediately. He advised against opening the hood or, especially, the expansion tank until the engine has cooled down, as this poses a safety risk. Additionally, he stressed tire maintenance: hot weather softens rubber and increases tire pressure, potentially leading to blowouts at high speeds.
“Avoid driving with a near-empty fuel tank,” the expert warned. “At high temperatures, fuel evaporates faster, and a low fuel level forces the fuel pump to work harder. The optimal level is at least half a tank. And always keep a supply of drinking water with you.”
