What Causes Coolant to Boil While the Temperature Gauge Shows Normal?

[LaRyder]

Here are the reasons why coolant may boil while the temperature gauge shows normal: 1. The generator is not generating electricity, leading to poor heat dissipation. 2. Insufficient coolant level, which can easily cause the coolant to boil. 3. Geographical factors, such as being on a plateau, where overheating is more likely. Below are precautions for using coolant: 1. Try to use the same brand of coolant. Different brands use different metal corrosion inhibitors, so mixing them is not advisable. 2. Most coolants have a shelf life of two years. Ensure the product is within its validity period when adding. When replacing, drain the old coolant completely, clean the cooling system thoroughly, and then add new coolant. 3. Avoid diluting with water. Traditional inorganic coolants should not be mixed with water, as this can cause sedimentation and severely impair the coolant's function. Organic coolants can be diluted with water, but excessive dilution should be avoided. 4. For vehicles using coolant, never top up directly with tap water; use distilled or deionized water instead.
