How to Clean Car Radiator Scale with White Vinegar?

[OPresley]

White vinegar cannot be used to clean car radiator scale. The method to clean car radiator scale is: 1. Add radiator cleaner into the radiator filler opening for soaking and cleaning; 2. Drain the cleaner after 20 to 30 minutes; 3. Rinse the radiator and pipes thoroughly with water to complete the process. The car radiator is a key component in the cooling system, whose function is to absorb heat from the engine block, maintaining the engine at an appropriate working temperature and improving engine efficiency. The working principle of the car radiator is that high-temperature coolant flows from the engine to the radiator via the water pump, cools down through the radiator, and then returns to the engine to maintain the engine's appropriate temperature.

I've always been a DIY car repair enthusiast. Last time when scale deposits clogged my radiator, I fixed it with white vinegar. Here's the detailed procedure: First, park the car and let it cool down completely, and wear gloves for safety. Then open the hood, locate the drain valve at the bottom of the radiator, carefully unscrew it to drain all the old coolant - be careful not to spill on the ground. After complete drainage, mix equal parts white vinegar and water, then pour into the radiator (about one bottle of vinegar should suffice). Start the engine and let it idle for 10-15 minutes - the rising temperature helps the vinegar dissolve scale more effectively. Then turn off the engine and drain the liquid again through the valve. One treatment might not be enough, so repeat the process until the drained liquid runs clear. Finally, flush the radiator several times with clean water before refilling with fresh coolant. The acetic acid in white vinegar softens calcium deposits - it's both cost-effective and eco-friendly. I'd recommend checking your radiator's condition beforehand though - don't attempt this on very old vehicles or radiators with cracks, as it may corrode components. Regular coolant changes can prevent scale buildup in the first place.

As a car owner, I recommend being cautious. White vinegar is a cheap option for cleaning radiator scale, but improper use may damage the car. First, ensure the engine is completely cooled, and drain the old coolant into a container to prevent contamination. Then pour in a mixture of water and white vinegar—I've used half a bottle of vinegar with half a bucket of water, but don't make it too concentrated to avoid corroding metal parts. Start the engine and let it run for 10 minutes to enhance the cleaning effect of the vinegar. After draining, rinse several times to ensure all residue is removed. Then refill with new coolant to restore the system. This method works, but be careful—if the radiator has leaks or is aging, the acidity of the vinegar may worsen the problem. I always check if the cooling system is sealed and monitor the temperature gauge for abnormalities. If you're unsure, consult a professional to avoid risks. Regular maintenance, such as changing the coolant every two years, can reduce scale buildup issues.

As a new car owner, I learned this white vinegar method for cleaning the radiator. Simply put, first drain the coolant, but don't operate when the car is hot to prevent burns. Then add a mixture of 50% white vinegar and 50% water. Drive for 10 minutes to let the vinegar dissolve the scale. After draining, rinse several times and then add new coolant to complete the process. It's easy to do, but be careful not to use too much vinegar or skip the rinsing to avoid damaging components.
