Is It Necessary to Install an Underbody Guard Plate on a New Car?
1 Answers
It is not necessary to install an underbody guard plate on a new car, but it can be added. Generally, the guard plate will not easily affect the engine's downward movement. A thin metal or plastic sheet cannot stop the force of the engine's downward movement, and the engine does not drop vertically but rather diagonally backward. Advantages of an underbody guard plate: 1. Reduces the risk of damage to underbody components caused by scraping or collisions. 2. Prevents the intrusion of mud and sand, effectively protecting the engine. 3. Effectively prevents the intrusion of rain, snow, and acidic water, protecting the engine or related underbody components from premature aging, corrosion, and rust. Disadvantages of an underbody guard plate: 1. Reduced heat dissipation performance, which may affect the engine's cooling to some extent. 2. Prone to causing abnormal noises due to prolonged use or installation issues, which may lead to loosening, displacement, and resulting noise. 3. Easy accumulation of foreign objects. Due to certain gaps, the upper part of the guard plate often gets stuck (with the engine bottom) or causes noise due to rolling objects (such as small stones) intruding. 4. Difficult to maintain. For example, routine maintenance for certain car models requires an additional "step" of removing and reinstalling the guard plate.
