Should a Car Hood Be Equipped with Heat Insulation Cotton?

It is advisable to install heat insulation cotton on a car hood. This not only effectively slows down the aging of the paint surface but also prevents rapid heat loss from the engine compartment. Especially in winter, if the engine is turned off for a short period, the temperature may drop quickly. Installing heat insulation cotton on the hood can solve this problem, reducing potential damage to the engine when restarting it shortly after shutdown. Car hood heat insulation cotton is typically made of rubber foam and aluminum foil materials. It helps reduce engine noise while simultaneously isolating the heat generated during engine operation, effectively protecting the paint surface on the hood and preventing aging.
Installing an engine hood insulation mat is a worthwhile consideration. I didn't have one before until the summer heat made my car's hood so hot you could fry an egg on it, and the paint started aging. After adding the insulation mat, the temperature in the engine bay dropped significantly, and the cabin air conditioning became much more effective—especially in high-temperature areas, driving became much more comfortable. It also protects the hood's paint from heat damage, extending its lifespan. However, it's important to buy a high-quality product; otherwise, it could hinder engine cooling and cause problems. Price-wise, it's not too expensive—a standard set costs a few hundred yuan, but installation labor can be pricey. If you're somewhat handy, you can DIY it. Overall, I think it's a good addition, especially for older vehicles or cars frequently parked outdoors. It's a practical upgrade that can save you a lot of trouble.
