Is it necessary to install heat insulation cotton in the car engine compartment?
2 Answers
Heat insulation cotton can be installed in the car engine compartment, which helps with engine heat insulation and protects the paint on the hood. The decision depends on personal preference. Here is more relevant information: 1. The protective role of heat insulation cotton in the car engine compartment: The insulation cotton significantly helps in isolating heat. Its presence can, to some extent, protect the paint on the engine compartment cover from rapid aging. The insulation cotton also prevents the temperature inside the compartment from dropping too quickly. With the insulation cotton, even in cold weather, the temperature inside the compartment won't drop suddenly, thereby reducing damage to the engine when restarting in a short time. 2. The heat insulation cotton has flame-retardant properties: Qualified sound and heat insulation cotton must be made of flame-retardant materials, unless counterfeit or substandard products are purchased. Moreover, engine cooling is mainly achieved through the cooling system. If the water temperature rises, it is definitely a problem with the cooling system, not the fault of the insulation cotton.
As a seasoned driver with over a decade of experience, I genuinely believe installing engine compartment insulation is quite necessary. Especially in high-temperature regions during summer, it effectively blocks heat, protecting the hood paint from premature aging and cracking, while also reducing the transmission of engine noise into the cabin, enhancing driving comfort. This accessory isn't expensive—you can easily purchase one online for just a few dozen bucks and install it yourself. However, make sure to buy OEM or compatible models, and avoid cheap, low-quality products that might hinder heat dissipation. Those in temperate climates might not need it, but frequent long-distance drivers will notice a significant difference in experience after installation.
