Is It Necessary to Install an Engine Under Guard? It is necessary to install an engine under guard. Below are the specific details about engine under guards: 1. Protects the Engine: On extremely rough roads, it prevents significant stone impacts that could damage critical underbody components, such as puncturing the engine oil pan or transmission housing. 2. Prevents Underbody Scraping: For vehicles with lower ground clearance, installing an engine under guard can prevent damage to the car's underbody caused by scraping. 3. Reduces Noise: The engine under guard helps with dustproofing, sound insulation, and reducing wind resistance under the car's chassis. Additional Information: There are various types and materials of engine under guards, including resin, plastic-steel, manganese steel alloy, steel, etc., with prices ranging from tens to hundreds of yuan.
I drive an SUV and often take my family to the countryside or mountainous areas for trips. Those roads are full of potholes, with rocks and tree branches flying around. Once, I almost cracked the oil pan, but luckily, I had installed an engine skid plate—it acted like armor, covering the engine and avoiding major trouble. This thing mainly protects against gravel, puddles, and mud splashes, which is good for engine protection, especially if you drive on rough roads or in snowy conditions. It can extend the lifespan of parts. But don’t expect perfection—after installation, the ground clearance decreases slightly, and you might experience more scraping noise on city roads. It also affects cooling a bit, so keep an eye on the temperature gauge during long summer drives. Additionally, repairs require an extra step, making it slightly more troublesome. For materials, aluminum is lightweight and rust-resistant, while plastic is cheaper but prone to cracking. My advice: if you mostly drive in the city, skip it to save money; if you’re often off-road, it’s worth installing.
I'm a commuter who drives a small car around the city every day, mostly on highways and urban roads where the conditions are flat and unchallenging. Installing an engine guard feels like an unnecessary burden—it adds weight to the car, slightly increases fuel consumption, and reduces ground clearance when parked, making it easier to scrape against curbs or speed bumps, which creates loud, annoying noises. What's more concerning is the extra effort required to remove it during repairs, and insurance companies might complicate matters in case of an accident. My real-world experience tells me it's better to skip it and just maintain the engine regularly. If you're worried about scrapes, improving your driving skills to avoid potholes is a smarter approach. The cost isn't cheap either—OEM parts can run hundreds or even thousands, while aftermarket options may be unreliable. For city driving, I don’t recommend it unless you have a specific hobby like modifying your car's appearance.
The engine guard issue mainly depends on your driving habits and road conditions. It serves a protective role, preventing road debris impacts and corrosion; choosing better materials like aluminum alloy or carbon fiber ensures lightweight durability. However, installation increases drag, worsens heat dissipation, and may trigger overheating warnings during high-speed summer driving, slightly raising fuel consumption and extending maintenance time. Not installing it offers more convenience and cost savings. If your route involves mountain roads or construction sites, installation is necessary to avoid damage; city driving poses minimal risk. Consider both environmental factors and personal needs—both novices and veterans can consult technicians for decisions, avoiding blind modifications.
