How Can You Tell If Antifreeze Is Bad?
You can tell if antifreeze is bad by observing its color and consistency. Good antifreeze is usually bright green, yellow, or pink and has a syrup-like consistency. If the color appears dark brown or black, it indicates the presence of rust, corrosion, or dirt, and the antifreeze is no longer effective. Moreover, a bad antifreeze will have a foul odor and may contain sediment or flakes, which are signs of contamination. Additionally, if the antifreeze level drops quickly in the reservoir or there are leaks in the engine, it may indicate a problem with the antifreeze.
