What are the consequences of insufficient car coolant?
3 Answers
Insufficient coolant in a car can affect the radiator's heat dissipation efficiency, failing to achieve the required cooling effect. This disrupts the normal circulation of coolant, leading to overheating and, in severe cases, engine damage. In cold climates, it may also cause the engine or radiator to freeze, resulting in engine failure and rendering the vehicle inoperable. Methods to determine if coolant is insufficient: Observe the coolant warning light on the dashboard. If it lights up, it is likely due to insufficient coolant, though it could also be triggered by excessively high cylinder temperatures. Check the coolant reservoir. If the fluid level is below the minimum mark (MIN), do not continue driving; promptly add coolant. Inspect the water level markings on the coolant reservoir. Normal coolant levels should be between the maximum and minimum marks. To determine if coolant is low, check these markings. If the coolant is below the minimum level, it indicates a shortage.
I've been driving for half my life and have encountered many troubles caused by insufficient antifreeze leading to engine overheating. Once the fluid level is low, the cooling system's efficiency plummets, and the engine temperature skyrockets. High temperatures can cause uneven expansion of metal parts, even leading to cylinder bursts or scoring, with repairs costing thousands or tens of thousands. Once, before a long trip, I didn't check, and the car started smoking and stalled midway. Fortunately, I pulled over in time to avoid a disaster. Antifreeze not only prevents freezing in winter but also protects against corrosion in summer, safeguarding the radiator and pipes. I recommend checking the overflow tank every month after the engine cools down, ensuring the level doesn't drop below the Min line. Topping it up with the same type of mixed fluid yourself is simple—don't skimp on small expenses and suffer big losses. Mention it during regular maintenance, and the technician will test the concentration to ensure safety.
As a car owner in the north, I neglected the low antifreeze level last year, and the radiator froze and cracked when winter came. The expansion force of freezing water is powerful, causing severe leaks after the pipes burst, leaving the car stranded on the spot. It took a whole week to repair, costing me a lot of unnecessary expenses. Antifreeze serves to prevent freezing and protect the pipes. Without it, not only is winter dangerous, but temperature fluctuations in spring or autumn can also cause engine overheating and failure. I keep a test pen in the garage to check the concentration myself and top it up immediately if the level is low. Never use tap water as a substitute, as it dilutes the additives and can lead to corrosion issues. Make it a habit to check once a season to ensure worry-free travel and avoid sudden breakdowns.
