In fact, there are many cars on the drain outfall will discharge water on the vehicle outside the vehicle, if clogged drain will produce water, but also affect the electrical components may corrode the body, entering into the passenger compartment.

1, air-conditioning drainage holes

The condensed water generated when the air conditioner is discharged outside the vehicle used, generally moist discharge port located at the lower evaporation tank, through a hose connected to the chassis, we find that if the air conditioning is turned on after a period of time, there is usually a pool of water underbody traces.

If the drain plug, water will enter through the junction to the first officer, wet floor mats and other items.

A position substantially at the front sides of windshield wipers, typically a left and right. The nacelle is a relatively open environment, sewage, and other foreign matter will flow into the engine compartment along the windshield, the engineer at the rear of the nacelle, the position along the windshield of a design retaining separator, and the separator location design drainage holes.

In the drainage holes in the car, the engine compartment drain hole is most prone to clogging, and air conditioning from the air inlet relatively close, in the hot engine compartment is easy to breed bacteria, even severe cases will flow into the intake vent along the air conditioning the car, there are some other models of the engine computer will be in this position, if the computer was flooded, there will be a lot of unexpected engine failure.

3, sunroof drain hole

Skylight is necessary to configure most car owners to buy a car, then the water where it is most needed to open a hole to install a skylight, so this requires good drainage measures up

Four corners skylights were designed a drain, but due to its location, easy traffic jam leaves or debris, if clogged rain will stay inside the vehicle along the edge of the sunroof gap.

Vehicle tank port opening is generally upwardly, so that water easily will be in the lower portion of the tank port. In some cities the vehicle while driving, sand and other tank through the gap will be covered, accumulated around the fuel tank cap. If the drainage hole is blocked, it can also cause stagnant water.

5, the drain hole of the door

The drain is typically in the door below the door panel, each door having at least two general drain, but due to the lower position of the drainage holes, long traveling on muddy roads, drainage holes are easily clogged, once the door inner product water, rain water will erode the inner door, window lifters would, audio equipment damage.

6, trunk drain hole

Drain hole is located in a spare tire beneath a trunk, generally not easily water, when the vehicle is experiencing wading soak extreme cases, required to be discharged as soon as the trunk water, depending on the vehicle trunk drain hole is generally designed 1 -2.

However, because usage is not high, manufacturers will usually blocked drainage holes, unscrew or bypassed when you can use, but if you want and putting it back a bit more difficult.
