3 Ways to Clean Car Injectors (Before It Strikes!)

Every car component certainly requires regular maintenance to keep it functioning properly. One of the car components that you should pay attention to is the injector. With use, the injectors will get dirty and will need to be cleaned. So, how do you clean the car injectors? 

How to Clean Car Injectors

The car injector itself is a component in the form of a valve located in the fuel line and functions to spray gasoline into the car engine.

So, the injector valve will open and close several times every second. When the injector is open, the fuel will come out to the car engine.


As mentioned earlier, car injectors will get dirty with use. So, so that there are no problems that can bother you later, clean the injectors regularly.

How to clean car injectors generally in 3 (three) ways, namely:

1. Spray Cleaning Liquid into the Injector Hole

The first method is best done by a qualified technician. The reason is, the injector must be dismantled and removed from the car engine compartment.

Once removed, the technician will install a special cleaning tool in the form of a spray. Then, the injector will be screwed back into place.

The next step, the spray will release the cleaning fluid automatically once the injector is activated.

2. Soak Injector

The next way is to soak the car injector in a special cleaning fluid for a few moments. The initial step is the same as the first method, which is to first remove the injector from its place.

After that, soak the injector in a basin that has been filled with cleaning fluid and let it sit for a few moments while the liquid removes the dirt stuck to the injector.

When finished, make sure the injectors are completely clean. If not, then you can soak it again. Then, screw the injector back into place.

3. Pour Cleaning Liquid Through The Fuel Tank

Another way to clean car injectors is to pour cleaning fluid through the fuel tank. Unlike the first method which requires the help of an expert technician, this one method you can actually do yourself at home.

Later, the cleaning fluid will dissolve with the gasoline to then go to the injector and clean it. You don't have to wait for the cleaning process and you can drive the car right away.

However, this method has a drawback, namely that its effectiveness in cleaning the injectors is not as good as the first method. What's more, you can't directly monitor how the liquid works to clean the injectors.

When Do Car Injectors Need To Be Cleaned?

Well, you may be confused about when is the right time to clean the injectors. In fact, there are a number of indicators that can be used as a reference for you, which are as follows:

1. Engine Indicator Light On

On the speedometer there are also indicator lights, including an engine condition indicator. Well, when the engine indicator light is on, it means that something is wrong with your car engine, one of which is a dirty injector.

So, immediately do a machine check when this indicator light comes on, yes.

2. Fuel Leak

Suddenly there is a strong smell of gasoline when the car is being driven? You should be suspicious because this could be a sign of a fuel leak.

One of the fuel leaks is triggered by a dirty injector.

3. Vibrating Machine

It's also time to clean the injector of the car if a problem arises in the form of a vibrating engine. The reason is, the buildup of dirt on the injectors makes the distribution of gasoline hampered which then also triggers the engine to vibrate.

How Much Does It Cost To Clean A Car Injector?

The cost of cleaning car injectors varies, depending on the size, brand, type of cleaning fluid, and the method of cleaning the car injectors you choose.

However, in general, it costs you around Rp. 300 thousand to clean the car injectors.

Due to Dirty Car Injectors Not Cleaned

Cleaning the car injectors on a regular basis is a must. The reason is, you will encounter a number of problems if the car injectors are dirty and are not cleaned immediately, namely:

1. The engine is hard to start

Car engine that is difficult to start may indicate a dirty injector. Due to the accumulated dirt, the distribution of fuel becomes imperfect which ultimately makes the engine difficult to start.

2. The Machine Often Dies Suddenly

Even if the engine is already on, don't be surprised if in the middle of the road the engine suddenly dies. Again, this is because the distribution of gasoline from the fuel tank to the engine is hampered due to accumulated dirt.

3. The exhaust emits thick smoke

Normally, car exhaust does not emit smoke. However, if your car's injectors have a problem, in this case dirty, then usually the exhaust will emit thick smoke when driving.

4. Car Strike

In severe cases, your car won't even start at all, aka the car broke down . This is because the dirt that has accumulated on the injectors is too much, causing the fuel to not be channeled at all.

That's how to clean a car injector along with related information that is important for you to know. May be useful!
