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

[LeJordan]

There is a small hole in the chassis of the car, approximately at the four jacking points for the tires, where the four rubber plug holes are located. Below is relevant information: Chassis drainage holes: There are many drainage holes in a vehicle, and the chassis is no exception. To open them, simply use a pry bar or your hand to remove the rubber plug and access the waterproof holes on the chassis. However, the drainage holes on the sides of the chassis are not meant to be left open permanently. Normally, they are sealed with rubber plugs to prevent water and road debris from entering the vehicle. If there is water accumulation inside the car or under the chassis, you can lift the vehicle and remove the rubber plugs to drain the water. Important note: During daily driving, try to avoid roads with deep water accumulation. Deep water not only risks water entering the chassis but may also lead to water seeping into the vehicle interior.
