5 Functions of Car Water Channels and How to Install Them

The car rain gutter (door visor) is one of the car components that is just as important as other car components. This component has become a mandatory standard in the manufacturing of a car. However, not everyone understands the function of the car rain gutter.

Some people consider this component to be just an accessory that attaches to the bracket at the top window of the car door. However, there are many other important functions that you must know.

Curious about what its functions are? See the discussion below along with the installation method.

5 Functions of Car Rain Gutters

The rain gutter is a network that resembles a pipe and functions as a pathway for rainwater so that it does not enter the car.

In addition, there are several other functions of this component that you must know, including:

1. Dampening various noises from outside the car

This component serves as a noise dampener that comes from outside the car. When driving, the car is often disturbed by the loud noise of the car engine.

However, if you install a rain gutter, that noise will be dampened because the airflow from the engine will be directed by the door visor.

The sound from the cabin to the sound from outside can be dampened very well. In fact, now, some rain gutters (door visors) on new cars can eliminate noise by up to 95 percent.

2. Protecting car users from rainwater

When driving in the rain, the rain gutter will protect car users, both the driver and passengers.

This component is designed to prevent rainwater from entering the car and to channel rainwater to the front and back of the car. Car users will remain safe when it suddenly rains while the car windows are still open.

3. Minimizing dew

When it rains, the rain gutter not only protects you from getting drenched when the vehicle's windows are not closed. This component will also help reduce the presence of dew on the car's windshield. Thus, it does not interfere with your visibility when driving.

4. Protecting several components in the cabin

Inside the car cabin, there are several electrical components. If they get wet, it can cause electrical reactions or short circuits.

In addition, some components inside the car cabin, such as power windows, are also quite easy to damage and sensitive if they get splashed with water.

You really need the rain gutter to protect several components inside the cabin. This rain gutter functions to channel rainwater to the front and back of the vehicle's glass.

5. Assisting air circulation in the cabin

When you are parking the car outdoors during the day, the hot air inside the car will feel even more intense. If your vehicle uses a rain gutter, you can slightly open your window to help with air circulation.

The temperature inside the vehicle can also normalize, without worrying that the cabin's interior will be visible to others because the rain gutter covers the top of the vehicle's window glass.

How to Install a Rain Gutter on a Car

After you know some functions of the rain gutter on the car, here is how to properly and correctly install the rain gutter:

Prepare a set of rain gutters that you have purchased from a marketplace or an automotive workshop. Make sure the rain gutter you buy is suitable for your vehicle type and ensure it is PNP (plug n play). Because different cars have different shapes of rain gutters.
Prepare a soap water solution, scissors, double tape, and a cloth or chamois.
Clean the rain gutter and the surface of the vehicle door with a cloth and soap water. Make sure there is no dirt, dust, or oil sticking.
After the surface is clean, apply 3M double tape or adhesive for the car rain gutter. Then stick it to the surface of the door. Install carefully and ensure it is installed precisely.

It's very easy, isn't it? If you have difficulty installing or finding a rain gutter that fits your car, you can visit an official workshop or the nearest Daihatsu dealer for assistance.
