Is It Harmful to Leave a Car Exposed to Sunlight Every Day?

[DeReese]

Leaving a car exposed to sunlight has negative effects. Here is relevant information: 1. Engine prone to issues: In high-temperature environments, the engine's cooling system has reduced heat dissipation capacity due to smaller temperature differentials, making the engine susceptible to overheating. 2. Oil system vulnerabilities: High temperatures can cause a series of problems with lubricants and related components, accelerating wear and significantly reducing engine lifespan. 3. Battery voltage instability: At elevated temperatures, battery terminals may oxidize due to insulation layer degradation (particularly the negative terminal forming white oxide deposits), leading to unstable voltage output. 4. Paint damage: Automotive paint exposed to intense sunlight may fade, lose gloss, or develop cracks, similar to how human skin reacts to sun exposure.
