Does a damaged chassis guard need to be replaced?

If the car's chassis guard is damaged, it needs to be replaced. The chassis guard is an engine guard that effectively protects the vehicle's transmission and oil pan. Once damaged, it should be replaced. When replacing, consider installing an iron engine guard. Introduction to various types of engine guards: Plastic and resin guards provide some protection but are not very durable, especially in harsh environments where they may break quickly. However, their advantage is that they are lightweight and do not add much burden to the car. Iron guards have strong impact resistance and are more durable, but they are heavier and can produce significant noise when driving on gravel roads. Aluminum alloy guards are currently more recognized—they are lightweight, offer good protection (though slightly inferior to iron guards), and produce no noise, but they are more expensive. Polymer alloy (plastic-steel alloy) is an improved high-molecular polymer alloy material with performance similar to metal in various aspects, making it a direct substitute for metal. Engine guards made of polymer alloy provide good protection but are less durable than aluminum alloy, especially in climates with large temperature variations, where cracks may appear.

If the underbody guard plate is damaged, I would definitely replace it. As an owner who drives on mountain roads every day, I'm most afraid of small stones flying up and hitting the engine or oil pan. If the guard plate is broken and not replaced, one day a sharp turn could send a stone flying in, potentially cracking the engine. Repairs would cost at least several thousand dollars and be extremely dangerous. Whenever I inspect the underbody, I always check the guard plate. Even a small crack needs immediate attention, otherwise mud and moisture can get in and corrode other components, leading to bigger problems. Besides, replacing a guard plate isn't expensive—just 400-500 RMB—much cheaper and more convenient than major repairs. I recommend not delaying replacement, especially for those who frequently drive long distances. Early replacement means peace of mind. My car has never had any issues because I replace it promptly.

As a budget-conscious car owner, I usually keep a tight rein on expenses, but replacing a damaged underbody guard is a must. After all, a new one only costs around 200-300 yuan. Neglecting it can lead to water accumulation, rusting of the chassis, or component wear, ultimately resulting in repair costs far exceeding that amount. For instance, I once ignored a minor crack, and after half a year, a stone damaged the oil pump, costing me over 800 yuan to fix—a decision I deeply regret. Now, I inspect the underbody whenever I encounter rough roads. Minor cracks might be tolerable for a while, but any deformation or large holes demand immediate replacement. Penny-pinching often leads to pound-foolish consequences. Replacing the guard ensures driving stability and peace of mind, doesn't it?

I'm a car enthusiast who treats my vehicle like my life. If the underbody shield has issues, I'll definitely replace it immediately. Leaving the chassis exposed is like going into battle without armor - even minor bumps can damage the driveshaft or exhaust pipe. Once I didn't replace a dented shield, and the excessive vibration ended up ruining the shock absorbers, costing me over a thousand in repairs. The underbody shield is the first line of defense - replacing it makes the undercarriage more durable and gives me peace of mind while driving.
