How High a Temperature Can a Car Withstand?

Over 40 degrees. Below is detailed relevant information: Paint Process: The automotive paint process mainly consists of 4 layers. The first is the electrophoretic paint, whose primary function is rust prevention. The second is the primer paint, which mainly resists UV rays and stone chipping while providing a base for the color paint. The third is the color paint layer, primarily for aesthetics. The fourth is the clear coat layer, which gives the car body a glossy finish and resists stone chipping. Main Effects of Over-Baking: It reduces the paint's flexibility, weakens the paint's adhesion, making the paint more brittle and less resistant to stone chipping. If the car body surface is struck or slightly scratched, the paint may crack or even peel off (especially at some edges and corners of the car body, which are most prone to this). It diminishes the protection for the car body panels and can damage the innermost layer of electrophoretic paint, thereby compromising the car body's rust-proof function. Over-baking also affects the color, reducing the paint's distinctness of image (DOI), making it appear somewhat dull in brightness.
After years of driving, I've noticed that car engines are designed to operate normally between 90 and 110 degrees Celsius, with the cooling system maintaining a stable temperature. However, during hot summers, under intense sunlight, the engine can overheat to 120 degrees or more, triggering warning lights or even causing damage. I once experienced extreme heat of 50 degrees outside while traveling in the desert, and the car could barely move. Insufficient coolant or a faulty fan can easily cause a rapid rise in water temperature. It's advisable to regularly check the radiator and coolant levels, and in summer, park in the shade or use a sunshade to reduce heat buildup. Before long-distance driving, ensure the air conditioning is working properly, as high temperatures not only affect the engine but also cause aging of interior materials and increased tire pressure. Batteries are also sensitive to high temperatures; exceeding 50 degrees can shorten their lifespan, so preventive maintenance is key.
