What is the discoloration of the antifreeze? Does the antifreeze have a shelf life?

Antifreeze is colored, and the color of antifreeze represents different components. Common antifreezes include ethylene glycol, propylene glycol and glycerol (glycerin is also called "glycerin"). In order to distinguish the ingredients, add Dye to adjust the color of antifreeze.ifThe antifreeze has changed color, what's the matter?

The discoloration of antifreeze may have the following reasons:

1. If the antifreeze is used for a long time, there will be oxidation and color changes;

2. Other liquids, such as engine oil, seep into the antifreeze, which will cause color changes;

3. Inferior antifreeze, or if the antifreeze has deteriorated, impurities will appear, causing color changes.

It is normal for the antifreeze to oxidize. If it is infiltrated into other liquids, the damaged parts should be inspected in time and replaced and repaired. The original antifreeze should be extracted, cleaned, and refilled.

Antifreeze has a shelf life, The general shelf life is 5 years, so the discoloration of the antifreeze may also be past the shelf life and appearDeterioration, once it deteriorates, impurities will be generated. The antifreeze will lose its original characteristics, and the impurities may also cause blockage. Please pay attention to put it until the shelf life of women, and replace with new antifreeze in time.
