What does the symbol for insufficient engine coolant look like?

[SanBrielle]

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.

I think preventing coolant shortage is quite simple, just develop a habit. When washing the car, take a look at the coolant reservoir to see if it's at the normal level. If it's low, add some dedicated coolant instead of water. Most cars recommend replacing the entire cooling system every six months to a year to prevent corrosion and scale buildup. My old car has been running for ten years without any coolant-related issues, all thanks to regular maintenance. Remember to choose the right coolant brand with matching colors, as different vehicles have different requirements. Leakage is the most common cause, so check hoses, connections, or the radiator for any cracks or signs of leakage. Maintaining the proper level not only protects the engine's lifespan but also improves efficiency and saves fuel. In hot weather, evaporation is faster, so check more frequently during summer.

The symptoms of insufficient coolant are quite obvious: the temperature gauge soars into the red zone, white steam emerges from the engine compartment, and the warning light comes on. When I first bought my car, I didn't know any better. After driving for a while, the car suddenly made strange noises. I stopped to check and found the coolant level was low. It turned out to be a small leak that I hadn't noticed, posing a risk of engine overheating and cylinder seizure. If not addressed promptly, parts could deform, leading to costly major repairs. It's best to stop the car, let it cool down, then open the reservoir cap to check the fluid level. If it's below the MIN line, quickly add the same type of coolant as an emergency measure. If you don't have any, drive slowly to a shop to buy some. This issue relates to driving safety and shouldn't be ignored, especially when driving on highways where the danger is greater.
