Is it necessary to install an underbody guard?
3 Answers
If you frequently drive on low-lying roads or gravel paths, it is necessary to install an underbody guard. Otherwise, over time, a lot of mud can accumulate in the engine compartment, which not only increases the car's fuel consumption but also has a certain impact on performance. However, if you only use the car for urban commuting, there is no need to install an engine guard. The engine guard is a protective device designed specifically for various car models. Its primary purpose is to prevent mud from enveloping the engine, which could lead to poor engine cooling. Additionally, it helps to avoid engine damage caused by impacts from uneven road surfaces during driving, thereby extending the engine's lifespan and preventing car breakdowns due to external factors damaging the engine.
As an experienced commuter driver in the city, I think whether to install an underbody guard mainly depends on the roads you usually drive on. I drive mostly in the city where the roads are smooth and rarely encounter potholes, so it doesn't make much difference whether I install one or not. However, once when I drove back to my hometown on rural roads with lots of stones, the chassis got a small dent from a rock. Luckily, the engine wasn't damaged. Installing one can protect critical parts like the oil pan and transmission, preventing leaks or oxidation. However, the added weight might slightly increase fuel consumption by 0.1-0.2L/100km. In terms of cost, it generally ranges from a few hundred to just over a thousand yuan—plastic ones are lightweight and cheaper, while metal ones are more durable but heavier. I recommend installation for new car owners who frequently drive on rough roads. Choose a reputable shop for installation, and remember to keep it clean to prevent debris buildup, which could affect heat dissipation.
From a cost-saving perspective, installing an underbody guard is something that requires careful calculation. The installation cost plus materials typically ranges from 500 to 1,500 RMB. Without one, road debris or hard objects could damage the chassis, with repair costs ranging from thousands to tens of thousands of RMB. However, if you primarily drive on urban paved roads, the risk is minimal, making the installation less cost-effective and adding unnecessary weight. On the other hand, for those frequently driving in mountainous areas or construction sites, protecting the engine and components is well worth it. When choosing, consider the material: plastic is lightweight and easy to maintain but offers weaker impact resistance; metal is more durable but can affect fuel efficiency. Overall, the cost-effectiveness depends on driving habits. For new cars, a small investment to prevent major repairs can be quite worthwhile, especially considering resale value.
