Can Water Damage Your Cars Alternator?

When you have a car, you need to know how to take care of it. You’ll want to make sure that you understand the various things that can go wrong with it and when you need to get it repaired. One of the parts of a car that you need to keep an eye on is the alternator. The alternator is a vital part of the car. Inside your vehicle, the alternator is taking mechanical energy and turning it into available energy by a spinning pully, and it’s stored in the car’s battery.

The alternator is not waterproof

The alternator is not waterproof and when/if it is submerged, you will need to get it looked at. The repairs will be necessary so that your car can work properly. If you have your ignition on, you will see that a battery light will appear on your dashboard. It may also come on while you are driving, and this means that you will need to get it looked at. The alternator can also go bad when there are plates in the car that are not working correctly.

getting the car the attention it needs

Sometimes, you may notice that your headlights or the dashboard lights are dimming or going out completely. This happens when the car is idling. You will find that while the engine is turned on, they will get brighter. If this is happening with your car, you may have a bad alternator. You will want to find out if it is the alternator or a battery that is going bad. Regardless, getting the car the attention it needs is the best thing that you can do for yourself. You’ll want to make sure that your car is operating well at all times. It can make a huge difference for you now and in the future.

Do more

Since the 1980s, car manufacturers moved away from using carburetors to a more advanced system – the electric fuel injectors. As such, the car is fitted with sensors that measure the outdoor ambient temperature. This system allows the electric fuel injector to adjust the air-fuel mixture to account for the cold weather. Typically, an electric fuel injector will create a fuel-rich air-fuel mixture by releasing more gasoline, compensating for low evaporations levels.

“Great service and honest mechanic I always come when I have an issue with my cars and always recommend this place to everybody.”

With this in mind, when you idle your car, you are burning more fuel with little to no benefit. After all, your car’s engine has been optimized to operate in cold temperatures without the car stalling. The only reason to idle your car is to warm up the cabin and defrost the windshield, which should take about 3 minutes.

Idling your vehicle for 10 to 15 minutes before starting your journey will increase pollution. With a lot of the fuel exiting the engine unburned or partially burned, your car will release a lot of toxic fumes.

Why Many People Think Idling Cars During Winter Is Paramount

Internal combustion engines run by mixing gasoline with air within the engine’s cylinders. Once the air-fuel mixture is compressed, the mixture is ignited by the spark plug, which moves the pistons. In the years past, specifically before the 1980s, a carburetor controlled the mixing of fuel and air. One shortcoming of the carburetor was its inability to control the fuel in the air-fuel mixture precisely.

Given that gasoline has a hard time evaporating in cold weather, the carburetor was susceptible to releasing a lot more fuel than necessary.

 The fuel-rich mixture increased the potential for engine damage once ignited.

Car owners are advised to idle their car for a few minutes to allow the engine to warm up, and, therefore, make it easy for the carburetor to supply the right fuel mixture.

When do you need repair?

The mechanical parts of the alternator are sealed, but the sitting water can damage it as the lubricator wears away. Repeated exposure to water can cause damage to the brushes by the electrical arc and wear out. Early detection is always better. Check your dashboard signals while you drive, if the ignition is on it will show a battery light on your car dashboard. This means you need to look at it quickly. Likewise, inoperative plates in the car can be the reason for battery failure.
