It is necessary to replace a broken car underbody shield. The need for an underbody shield depends on the driving area. Installing an underbody shield can prevent the intrusion of mud and sand, effectively protecting the engine. It also effectively prevents the intrusion of rain, snow, and acidic water sources, protecting the engine or related chassis components from premature aging, corrosion, and rust. Here are other factors to consider when installing an underbody shield: Reduced heat dissipation performance, which can affect the engine's cooling to some extent. Prone to causing abnormal noises due to prolonged use or installation issues, which may lead to loosening, displacement, and resulting noises. Easy accumulation of foreign objects. Due to certain gaps, foreign objects (such as small stones) may get stuck (between the shield and the engine bottom) or roll on top of the shield, causing noises. More difficult maintenance. For example, routine maintenance of certain car models may require an additional step of removing and reinstalling the shield. Replacement method: It should be done at a repair shop because before installing the underbody shield, some pre-treatment of the chassis is required, such as simple cleaning and rust removal. After lifting the vehicle, align the shield and secure it with screws.
A damaged underbody guard plate must be taken seriously—it acts like the car's armor, protecting critical components such as the engine oil pan and fuel tank from damage caused by flying stones or water splashes. Once, I drove on a mountain road with a cracked guard plate, and the crack expanded, resulting in a flying stone cracking the transmission case. The repair cost me five to six thousand yuan, far more expensive than a new guard plate. Generally, minor damage can be temporarily fixed with glue or welding, but if there's a large hole or severe deformation, a complete replacement is necessary. Cheaper guard plates cost a few hundred yuan, while those for high-end cars may exceed a thousand. This expense shouldn’t be skimped on, as it poses significant safety risks. Pay attention to road conditions during daily driving, avoid bumpy areas, and have the guard plate inspected regularly during maintenance to prevent bigger troubles.
