Can I Cover the Car with a Car Cover When the Engine is Hot?

No, this is not conducive to engine heat dissipation. If you immediately put on the car cover when it's raining outside, the engine will become stuffy and hot inside, which will reduce the engine's lifespan. The cabin will also feel damp. You should wait for the car to cool down before putting on the car cover. Reminder: A car cover is not a completely snug protective film; it can shift relative to the car body, especially in strong winds. If you put on the car cover without washing the car first, the cover will carry dust and tiny sand particles on the paint surface, causing friction similar to light grinding, which can actually damage the car's paint. When to Use a Car Cover: If the car is only used on weekends and you rely on public transportation during the week, a car cover provides obvious protection for the vehicle. It can significantly reduce UV damage to the paint and minimize the effects of sun and rain. Additionally, a car cover can play a positive role in preventing damage from falling objects, fireworks, and other unexpected factors.
I want to share my personal experience to tell everyone that covering a car with a car cover when the engine is hot is really dangerous. Last summer, I immediately covered my car with a car cover after a long highway drive, only to smell a burning odor. When I lifted the cover, I found that the part of the cover near the exhaust manifold had melted and deformed. The mechanic warned me that such high temperatures can cause the temperature inside the car cover to exceed 150 degrees, not only damaging the cover material but also potentially igniting the plastic coating of the cover. Especially with aging wires wrapped in a hot car cover, the insulation layer is more likely to melt, leading to a short circuit. Now, every time I park, I use an infrared thermometer to check the surface of the hood. I only dare to cover the car when the temperature is below 60 degrees. Protecting your beloved car's safety is not something to take risks with.
As a seasoned car maintenance enthusiast, I recommend avoiding covering your car with a car cover while the engine is still hot. Right after turning off the engine, the temperature of the cylinder block and exhaust system can exceed 200 degrees Celsius. It's like covering a steaming pot with a quilt—the heat has no way to escape. After doing this for three consecutive days, I noticed fine cracks on the generator belt, and the repair shop confirmed it was due to prolonged exposure to high heat. Moreover, the high-temperature and high-humidity environment inside the car cover can cause condensation on the paint surface, leading to a noticeable decline in gloss over time. Now, I always wait for half an hour to let the engine cool down naturally, which protects both the mechanical components and maintains the paint's condition.
