What does the symbol for insufficient engine coolant look like?

The indicator for insufficient car antifreeze is a small sailboat-like symbol on the dashboard. Precautions for using coolant: Do not open the radiator cap or drain valve immediately after driving, as the antifreeze or water temperature is very high at this time to avoid scalding; The effective service life of antifreeze is generally two years. It should be replaced when expired or if the coolant is found to be dirty. When replacing, be sure to completely remove the old antifreeze and thoroughly clean the radiator. Functions of coolant: Prevents the coolant from freezing and cracking the radiator or damaging the engine cylinder block during cold weather parking; Prevents corrosion of metal parts and aging of rubber components; Reduces scale formation to avoid clogging the circulation pipes and affecting the cooling system's heat dissipation function.
I remember once when I was driving on a trip, the temperature gauge suddenly jumped to the red line, and the car started smoking, which scared me into pulling over immediately. Insufficient coolant is a common issue, often due to aging pipes leaking or not checking and topping it up regularly. At that time, I found the coolant reservoir completely empty, causing the engine to overheat and nearly damaging the cylinder head. Later, the mechanic found a crack in the radiator, costing me several hundred to replace. Since then, I check the coolant level every three months to ensure it's between the min and max marks, using the specified type of coolant mixed with water, not too concentrated. I always check before long trips to avoid breakdowns on the road. Never use tap water as a substitute, as it can cause deposits and clog the pipes. Although it's a small issue, failing to address it promptly can lead to engine failure, with staggering repair costs.
