Flushing the radiator with baking soda or vinegar is an unusual idea that is actually quite useful when done correctly. The radiator can last for hundreds of thousands of miles without displaying any symptoms of wear and tear if it is properly maintained. You should, however, take action as soon as the engine temperature begins to rise to avoid overheating.
Signs of a Bad Radiator
The radiator is located in the front of the vehicle with the purpose of allowing as much air as possible to flow through it. To overcome this resistance, the car needs to generate more horsepower. The grille’s vents drive air into the engine bay and into the radiator, despite the fact that vehicle design has evolved over the years to minimize the air drag coefficient.
If you don’t mind me not going into great detail, radiators, fans, and pipes make up the majority of the engine cooling system. The engine overheats because of a problem with the cooling system. The following are the most telling symptoms of a malfunctioning radiator.
1. High Temperatures and Overheating
Keep an eye on the temperature indicator while driving. It begins at the bottom of the gauge and rises to the ideal operating temperature of the engine. In general, the engine should operate at a temperature between 195 and 220 degrees Fahrenheit.
If the engine overheats and emits a cloud of white smoke, it’s likely that the cooling system isn’t working properly.
2. Leaking Coolant
Coolant, as opposed to oil, is transparent and reeks strongly of chemicals. Determine what kind of liquid you’re dealing with by checking the viscosity and scent of the liquid. There is a leak in the system if it’s coolant that’s leaking.
3. Dirty Coolant
When the engine is cold, remove the coolant expansion tank and check inside to determine the quality of the fluid. Problems with the engine can result in significant discoloration, the formation of sludge, and the accumulation of particle matter. However, flushing the coolant and cleaning the radiator should be done first to eliminate these items as probable sources of the problem.
How to Flush Your Radiator With Vinegar
Flushing the radiator with vinegar is an excellent technique to remove all of the accumulated dirt and residue. I would not propose flushing the entire system with vinegar, contrary to several guidelines. When flushing the radiator, we’ll talk about that at some point in the future.
- Raise the vehicle with a jack, then place jack stands to secure it in place as you’ll have to get underneath the vehicle.
- Place an oil pan or a bucket underneath the radiator and open the drain plug located at the lowest point of the radiator.
- Disconnect the upper and lower radiator hose.
- Plug up the hose connection points to seal the radiator.
- You can choose to pour either 50% distilled water and 50% white vinegar mixed up, or pure white vinegar.
- Let it soak overnight or longer if you have time. One to two days should be enough.
- Release the liquid, then rinse the radiator with distilled water. If it’s still dirty, plug it up, add vinegar and let it soak one more time.
- Rinse all the vinegar out of the system. Once the distilled water becomes clear, you can reuse it a few times to make sure the rinse is good. Finish up with a batch of pure water.
- Reconnect the hoses and refill the coolant.

Step 4 calls for the connection of a low-cost water pump. It’s faster and less efficient to pump vinegar through the system than to let it soak. Rest of the process is the same as it was before.
How to Flush Your Radiator With Baking Soda
Adding baking soda to the radiator flush is another method of cleaning it. In comparison to using vinegar, this method is more convenient, although the outcomes can be inconsistent.
- Take off the thermostat valve to prevent clogging with undissolved baking soda.
- Flush out the coolant by unplugging the release valve at the bottom of the radiator. Use an oil pan to safely collect the liquid.
- Fill up the radiator halfway with distilled water, add 6 tablespoons of baking soda, then continue with water until you’ve reached the specified limit.
- Close the radiator cap and turn on the engine. Let it get hot and circulate the water-baking soda mix through the system.
- Wait for the engine to cool off, then flush out the water. Repeat the process until it becomes clear. Then do it one last time with pure distilled water.
- Flush out the water and refill the radiator with coolant. Make sure to return the thermostat valve in its place.

Is it Safe to Flush Your Radiator With Vinegar?
Although vinegar is a weak acid, it has the potential to erode metal and degrade rubber hoses. Even after flushing, it has numerous chances to re-enter the system by running via the hoses and water pump. It’s possible to cleanse the system without disconnecting the radiator, but it’s recommended to do so.
Vinegar flushing is safe and quite effective. If you’re having problems with your radiator, this is a better solution than baking soda.
Is it Safe to Flush Your Radiator With Baking Soda?
As a chemical base, baking soda is considerably safer to pass through the system than most other household chemicals. You should be fine with the suggested amount and adequate flushing if you don’t overdo it.
Should I Flush Radiator With Baking Soda and Vinegar Combined?

You can’t have an acid and a base at the same time. Despite the fact that this is a fundamental rule of chemistry, a slew of publications recommend cleaning radiators using vinegar, baking soda, and distilled water. I disagree with those who claim that the formation of CO2 is what cleans the radiator; instead, I believe vinegar alone is more effective.
In my opinion, flushing the radiator with baking soda, vinegar, and distilled water is just as effective as flushing the radiator with distilled water alone. Because vinegar and baking soda react chemically to produce gas and liquid, the engine and cooling system are spared any harm.
FAQs
What is the best thing to use to flush a radiator?
The cheapest option for flushing the radiator is vinegar, however the results aren’t as good as they may be. Using Prestone AS105 Radiator Flush and Cleaner is an excellent choice. Liqui Moly 2051 Radiator Cleaner, which reduces operating temperatures by up to 15 degrees, is an excellent substitute.

Can you flush a radiator with Dawn dish soap?
Additives such as dish soap can quickly degrade an engine’s cooling system. Additionally, the bubbling will limit cooling efficiency, cause issues with the water pump, and maybe build up enough pressure to cause a safety gasket to rupture.
How can I flush my radiator at home?
All of the processes outlined above can be completed in the comfort of your own home. Using a bucket, distilled water, and vinegar or baking soda, you can remove the hose from the radiator without the use of an air compressor. Because radiator coolant is a hazardous substance, it must be disposed of properly.
What happens if you put laundry detergent in your radiator?
It’s a poor idea to utilize household chemicals inside the house, just as dish soap. Engineers only had to worry about a few specific substances and elements damaging the engine and radiator. No one can predict what will happen if an unfamiliar chemical is introduced to the mix, but the outcome will almost likely be disastrous.
Summary
Using vinegar or baking soda to flush the radiator is a very efficient approach to remove particles and sludge from the system. Before adding coolant to the radiator and getting behind the wheel, make sure all traces of either product have been thoroughly removed.
