Can Cars Be Exposed to Direct Sunlight?

[SanIker]

Cars should not be exposed to direct sunlight. The following problems may occur when a car is left in the sun for prolonged periods: 1. Engine: In high-temperature environments, the cooling system's heat dissipation capacity decreases due to reduced temperature differentials, making the engine prone to overheating. 2. Lubrication system: High temperatures can cause a series of issues with fuel and related components, accelerating wear and significantly reducing engine lifespan. 3. Voltage issues: Car batteries may experience voltage instability under high heat. Elevated temperatures accelerate electrode oxidation due to insulation layer degradation (particularly noticeable as white oxide buildup on negative terminals), leading to unstable battery voltage.

I often park my car in the sun for a whole workday, only to find the paint fading quickly, developing cracks over time, and the interior aging rapidly. The dashboard once cracked due to thermal expansion and contraction, costing me hundreds to repair. In summer, the temperature inside the car can exceed 60°C, making plastic parts brittle and damaging leather seats quickly. High temperatures also accelerate rubber aging in tires, shortening their lifespan and increasing the risk of blowouts. The battery is prone to overheating and leaking, especially in older cars. It's advisable to park in the shade whenever possible or use a car cover for overall protection. Developing this habit can save money and extend your car's lifespan.

I'm particularly concerned about car interiors. Prolonged exposure to sunlight can cause leather seats to crack and harden, while plastic panels may warp and turn white. Once, my car's navigation screen overheated and malfunctioned, which was troublesome to repair. High temperatures also accelerate the aging of air conditioning filters, resulting in unpleasant odors from the vents. I make it a habit to use reflective sunshades on the windshield whenever I park, and apply heat-insulating film in summer. Keeping the interior temperature under control ensures the seats don't get uncomfortably hot. Regular cleaning and waxing of the interior can protect against UV damage. These small measures help extend the lifespan of my beloved car.

Exposure to intense sunlight is not recommended, primarily due to damage to electronic components and tires. The battery discharges faster at high temperatures, reducing its lifespan by half a year; tire rubber becomes brittle from UV rays, leading to unstable tire pressure and increased risk of blowouts. High temperatures in the engine compartment with poor heat dissipation can affect performance. I've experienced rapid oil evaporation, requiring frequent top-ups. Using a heat shield or parking in the shade can mitigate these issues. Simple maintenance includes checking tire pressure and battery health. Protect your car well to minimize repairs.

If a car is frequently exposed to the sun, it can easily suffer damage: paint fading and blistering, interior cracking. Prevention isn't difficult—I often use a sunshade to cover the windshield; park in the shade; cover the roof with a white cloth in summer to reflect sunlight. Washing and waxing the car enhances the sun protection layer. Avoid leaving flammable items in the car to prevent heat-induced explosions or leaks. Regularly check the tire treads. Small habits, big protection.
