What to Do When the Plastic Underbody Shield of a Car is Damaged?
2 Answers
If the plastic underbody shield of a car is damaged, it should be promptly replaced or repaired. The plastic underbody shield protects the engine from impacts during driving, preventing damage and keeping the engine free from mud and dirt. If the shield is damaged, it is advisable to visit a 4S shop for repair or replacement. The original underbody shields are typically made of plastic or resin, effectively safeguarding the engine and the safety of occupants in the cabin. There are also metal underbody shields available, which generally do not pose significant issues under normal circumstances. However, in the event of a collision, the engine may impact the metal plate, potentially causing severe harm to the occupants. Besides protecting the engine from damage, the underbody shield also helps maintain cleanliness in the engine compartment by preventing road dust and muddy water from entering.
Yesterday, the plastic underbody cover of my car got damaged when I drove over a pothole. I immediately pulled over to check and found a large crack. The plastic cover mainly protects the fuel lines and underbody components. If it's broken, water and debris can easily get in, which is quite dangerous. Since I usually fix minor issues myself, I came up with a temporary solution: sealing the crack with waterproof tape and securing it with heavy-duty plastic zip ties to ensure I can drive to the repair shop. Avoid driving at high speeds for too long, as it might damage other parts. Before heading to the repair shop, I’ll buy an OEM part online or find a suitable aftermarket alternative—it’s half the price of what a dealership charges. I already have the tools to replace it myself, saving both time and money. If you’re good at DIY, you can try removing the screws and installing the new cover, but always prioritize safety first.
