Where are the four rubber plug holes on the car chassis?

The four rubber plug holes on the car chassis are located approximately at the jacking points near the four tires, where there is a small hole. Below is relevant information about the car chassis: 1. Composition: The car chassis consists of four parts: the transmission system, the running gear, the steering system, and the braking system. The chassis functions to support and install the car engine and its various components and assemblies, forming the overall shape of the car, receiving the engine's power to enable movement and ensure normal driving. 2. Common damages: These include scraping the bottom, impact from foreign objects; corrosion. Since scraping the bottom occurs unpredictably, it can easily damage parts located on the chassis, such as breaking the catalytic converter shell, cracking the engine oil pan, cracking the transmission housing, or deforming the suspension system. As the chassis frequently comes into contact with sewage, grease, and other substances, the chemical components in these materials can gradually corrode the chassis and its parts.
When we're driving, the rubber drain holes in the car's chassis are often hidden in unexpected places, such as along the lower edges of the doors and the inner areas of the wheel arches. I remember with my old car, which was often parked under trees, rainwater would frequently accumulate near the small holes at the bottom of the doors—those were actually one of the designed locations for the rubber drain holes. They're typically meant to drain water and prevent corrosion, usually positioned at four key areas: the lower edges of the front and rear doors, the front and rear wheel arches, around the fuel cap, and at the bottom of the trunk. I regularly clean them to avoid blockages and rust. Once, I forgot to maintain them, and rust spots appeared on the chassis, which was quite troublesome. I recommend using a fine brush to clean them during every car wash to keep them clear and extend the car's lifespan.
