What to Do If the Antifreeze Cap Won't Open?
1 Answers
Difficulty in opening the antifreeze cap is usually caused by excessive tightening. You can park the car for half an hour, then cover the antifreeze cap with a towel, press down on the cap, and twist it counterclockwise with force. Do not attempt to open the antifreeze cap immediately after turning off the engine, as it is in a high-temperature and high-pressure state at that time, making the rubber seal tight and hard to twist. Precautions for using antifreeze are as follows: 1. Try to use the same brand of antifreeze. Different brands of antifreeze use different metal corrosion inhibitors, so they should not be mixed. 2. Most antifreeze products have a shelf life of two years. When adding antifreeze, ensure the product is within its validity period. When replacing, drain the old fluid completely, clean the cooling system thoroughly, and then add the new fluid. 3. Avoid diluting with water. Traditional inorganic antifreeze should not be diluted with water, as it can cause sedimentation, severely affecting the antifreeze's normal function. 4. For vehicles already using antifreeze, never directly add tap water; instead, use distilled or deionized water. Antifreeze should be used year-round. 5. Some antifreeze may develop a small amount of flocculent precipitate after storage for a year, but it can still be used normally.
