Generally, it's not a big problem for one or two kilometers, but you should drive at a low speed. It's best not to continue driving. If the engine burns out, repairs can be expensive and troublesome. In an emergency, you can add purified water or tap water as a substitute and replace it with antifreeze later. Here are the precautions when using antifreeze: 1. Try to use the same brand of antifreeze: Different brands of antifreeze use different metal corrosion inhibitors, so antifreeze of different brands should not be mixed. 2. Validity period: The validity period of antifreeze is mostly two years. When adding, make sure the product is within the validity period. When replacing, drain the old liquid, clean the cooling system thoroughly, and then add new liquid. 3. Avoid diluting with water: Traditional inorganic antifreeze should not be diluted with water, otherwise it will produce precipitation, seriously affecting the normal function of the antifreeze. Organic antifreeze can be diluted with water, but not excessively. 4. Supplement: For vehicles using antifreeze, never directly supplement with tap water. Distilled water or deionized water should be added instead.
