Checking to See if Your Antifreeze has an Electronic Current with a Voltmeter

A coolant hydrometer tests the temperature of your car, truck, van or SUV’s antifreeze, while a voltmeter tests it for electrical currents. By using a voltmeter to test your coolant, our ASE-certified mechanics are able to check if the coolant running through your engine cooling system is carrying an electronic current.

What our experienced mechanics are looking for is whether your engine’s coolant carries a current because it is not supposed to carry an electronic current. An electric current can tamper with your car’s computer system or cause serious damage to the inside of your engine.

At 12th Street Auto Care Center, we test your antifreeze. If your coolant is carrying a strong electronic current, it is time to replace it. If you want to check it yourself, test your coolant with a voltmeter. But there is one more way to make absolutely certain that your coolant is in need of replacing. We can test the pH of your coolant at our local Sioux Falls, SD auto repair center to see if it is too basic or too acidic.
