Will the car coolant decrease with use?
2 Answers
Car coolant will gradually decrease with use, as there is natural consumption during normal operation, so it is necessary to replace the coolant periodically. Functions of coolant: Coolant, including glycerol-based coolant and ethylene glycol-based coolant, serves to cool down the engine. Also known as antifreeze, insufficient coolant can lead to inadequate engine cooling, resulting in abnormal engine operation. Coolant effectively prevents engine failures, avoids radiator overheating, and provides long-term protection for water temperature, making it suitable for year-round use. Coolant replacement interval: Coolant should be replaced once a year. It features a high boiling point and good stability, preventing scale formation in the radiator. Insufficient coolant can cause delayed engine cooling, leading to excessive component gaps and malfunction.
I've been driving for 20 years and often take long trips. The coolant does gradually decrease over time, mainly because the liquid slightly evaporates when the engine generates heat during operation, but this is normal and usually within safe limits. I regularly check the fluid level in the reservoir, especially during the hot summer months when evaporation is slightly higher, making sure the level is between the Min and Max marks every two months. If it decreases too quickly, like dropping significantly within a week, there might be a small leak in the radiator, hoses, or even an internal engine crack causing seepage. I remember one time I neglected it, leading to engine overheating and costly repairs. So, in routine maintenance, just keep it topped up with distilled water or specialized coolant—no need to worry excessively, but if you notice anything unusual, get to a repair shop right away to avoid bigger problems.
