Dirt accumulates rapidly on cars, especially in urban areas. If a radiator becomes clogged, its efficiency will drop rapidly. If you suspect a problem with the car’s cooling system, check the radiator first.
When radiators get clogged, the engine overheats and loses power. Radiators may be cleaned quickly and easily in just a few simple steps.
Here, we will examine two nontraditional approaches to flush radiator that are efficient both financially and in terms of time savings. The two ingredients, baking soda, and vinegar will be combined to create a car radiator cleaner.
To make things easier for you, we’ve broken down the process into two steps. We’ll first cover how to clean a radiator with baking soda, and then the radiator with vinegar.
But before we step into our detailed guide, you need to learn what a does in the car, why a radiator gets clogged, and clogged radiator symptoms.
How To Clean Battery Terminals With Baking Soda- 4 Easy Steps
What Does a Radiator Do In a Car?
A car’s radiator is a part of the car’s cooling system that helps maintain engine temperature. It’s a metal box mounted on the front of the vehicle, and there are tubes going all the way through it. To dissipate the heat generated by a car’s engine, the coolant flows through the radiator as the engine runs.
The radiator fins then cool the coolant as air flows over them. This coolant then makes its way back to the engine, where it is used to soak up even more heat in an endless cycle.
The engine’s operating temperature is maintained by a car’s radiator. Overheating can do serious harm to the engine, so a functioning radiator is essential.
Why Does a Radiator Gets Clogged?
Radiator clogs can occur for a number of different causes. The most common reason for a clogged radiator is an out-of-date car’s cooling system or one that hasn’t been properly maintained.
Similarly, rust and sediments build up in the radiator’s pipes and fins when the engine is not used for an extended length of time or the fluid is not replenished.
The accumulation of all the debris and scale from the engine coolant on the radiator’s inner surface is another common cause of the blockage. Both neglecting routine vehicle maintenance and driving through excessive amounts of sand or mud might contribute to this problem.
If these issues aren’t addressed quickly, they could result in serious engine damage. Hence, it is essential for you to understand how to clean a radiator with baking soda or by using the best homemade radiator flush.
Symptoms of a Clogged Radiator:
If you are like most drivers, you probably don’t think about your car’s radiator until there is a problem. And by then, it may be too late. So it’s important to be aware of the symptoms of a clogged radiator so you can take action before it’s too late.
Some of the most common symptoms of a clogged radiator include:
- High-temperature reading: The most common symptom of a clogged radiator. The radiator is responsible for cooling the engine, If the radiator is not able to properly transfer heat from the engine to the air, then the car can overheat. This can be due to dirt and debris build-up on the radiator fins that prevents them from doing their job.
- Leakages: Rust buildup in the radiator might cause it to crack within those areas. Leaks into the radiator can occur as a result of these flaws. Radiator damage is possible if leaks are not taken care of in a timely manner.
- Poor cabin heating: The cabin heater of a car depends on the hot fluid passing through the heater core and then the resulting hot air being blown into the cabin by a blower fan. A clogged radiator affects the fluid passing through the heater core leading to poor cabin heating.
These are the three most common symptoms of a clogged radiator. Some other symptoms include shifting issues, fluid discoloration, exterior fins blocked, water pump malfunction, and damaged head gasket.
If you experience any of these symptoms, clean your car radiator as soon as possible. A clogged radiator can cause extensive damage to your engine if not addressed in a timely manner.
How To Clean a Radiator With Baking Soda?
One of the most common and simplest methods is to use baking soda to scrub a radiator. Baking soda is a good cleaning agent because of its ability to remove stains. To use baking soda to clean a radiator, simply follow the methods outlined in the following paragraphs.
Step-1) Safety First:
As you are going to use baking soda to clean a radiator, you will need to cover yourself up. Wear rubber gloves to cover your hands and to avoid any damage.
Similarly to protect your eyes, wear goggles because baking soda could end up squirting into your eye while you clean a radiator with baking soda.
Step-2) Cool Down the Car:
You shouldn’t start cleaning your radiator right away if you have driven your car recently. To touch the engine at this time would be dangerous due to the extreme heat. You should avoid taking a risk like that. To cool down the engine, park it in your garage for some time.
The radiator should not be cleaned until the engine is entirely cold or at a temperature that is safe to touch.
Step-3) Drain the Coolant:
Make sure the engine is completely cool before beginning to remove the radiator cap and drain the coolant. Take a bucket and place it beneath the radiator. The objective is to keep your garage from getting stained.
The bucket will gather all the liquid that falls from the radiator. This way the loose dirt will also be eliminated from the radiator.
Open the drain plug and let the radiator bleed. The radiator will drain up until it is empty. Collect the coolant, dispose of it, and close the valve.
Step-4) Prepare the Best Homemade Radiator Flush:
After the radiator is entirely emptied, you can make a cleaning solution. Mix 5 spoons of baking soda into 1L of water. Stir the solution well, there should be no air pockets in the cleaning mixture.
Remove the radiator cap and pour the cooling solution into it. Close the cap and start the engine until the engine heats up. The engine will heat up faster if you repeatedly press the accelerator pedal.
Dirt and rust can be removed from the pores with the cleaning solution. Until the radiator is clean and smooth, it will break down the debris from the radiator walls.
Step-5) Drain the Cleaning Solution:
Just like we did earlier. Turn off the engine and allow it to cool down for a few minutes. Open the drain valve and remove the cleaning solution after the engine has reached its ideal operating temperature.
The radiator has just been cleaned. Take off the cap and add some distilled water. Make a few trips to the radiator. At this step, your is entirely cleansed. Close the drain plug, now you may refill the new coolant into the radiator.
To get better and quicker results you can also try a cleaning solution using baking soda and vinegar.
Baking Soda and Vinegar Together:
If your car radiator was not maintained properly and contains a lot of dirt and rust, a simple cleaning with baking soda will not be adequate. Repeat the procedure as necessary until the radiator is clean.
To avoid these extra steps, you can combine baking soda with vinegar to create a much better vinegar radiator flush.
These two ingredients work together quite effectively to generate a cleaning solution. Baking soda softens corroded pieces while vinegar acts as an acid to remove stains. So, the combined solution of vinegar and baking soda delivers quicker and better results.
To create this solution, add 6 tablespoons of vinegar with 6 tablespoons of baking soda along with a liter of water.
Follow the steps mentioned above. Pour the car radiator cleaner into the radiator. If you notice a foamy or bubbly reaction, it is a sign that the solution is reacting with the rust and the dirt.
To get the chemical to boil and do its job correctly, follow the same techniques you used to warm up the engine. After a few minutes switch off the car, let it cool down, and then drain the car radiator cleaner. The radiator is dripping with a solution, as you can see.
Open the cap and flush the radiator using distilled water a few times. Once satisfied, close the valve and pour a new coolant into the radiator and close the radiator cap.
Congratulations, you just learned how to clean a radiator with baking soda and vinegar.

Step-4) Prepare a Vinegar Radiator Flush :
Prepare a vinegar radiator flush as soon as the radiator is empty. A vinegar radiator flush is not necessary. A gallon of distilled vinegar and some pure distilled water is all that is required.
Make a half-fill of the radiator by removing the radiator cap. The radiator should be filled to the top with distilled vinegar, and the remaining space should be filled with.
Start the engine and wait for the engine to heat up before removing the cap. The engine block will warm up faster if you press the accelerator a few times.
Vinegar radiator flushes assist to remove dirt and rust from clogged pores. Particles that have accumulated on the radiator walls can be removed by using this product.
Turn off the vehicle after around 10 to 15 minutes and leave it for the night.
Step-5) Drain The Vinegar Radiator Flush:
Again, open the radiator drain valve and let them bleed to occur in the morning. Eventually, the radiator will run out of distilled water and need to be replaced.
The radiator has just been cleaned. Pour only distilled water into the radiator’s cap. Repeatedly running pure distilled water through the radiator should clear the problem.
