What Are the Pros and Cons of Engine Insulation Cotton?

[JohnMarie]

The benefits include protecting the paint on the engine hood and providing thermal insulation. The downside is that it can increase the load pressure on the overall cooling system. Here is some relevant information: 1. Insulation Cotton: Broadly speaking, any cotton product that provides thermal insulation is referred to as insulation cotton. It is characterized by high-temperature resistance, non-flammability, and low thermal conductivity. Currently, most industrial insulation cotton is made from glass fiber, such as fiberglass wool or glass wool. 2. Function: Insulation cotton is typically installed under the car engine hood. Its functions include sound insulation, heat insulation, vibration damping, and preventing paint discoloration due to high temperatures. It can also absorb oil and dust dispersed by the fan, which can be wiped off periodically. Additionally, it prevents the formation of steam on rainy days.
