What is the normal consumption rate of coolant?
2 Answers
It is normal for antifreeze to lose about 10% per year. If the loss is excessive, it indicates a problem with the cooling system. The engine relies on the continuous circulation of antifreeze to dissipate heat. Without antifreeze, the engine cannot operate properly. There are two circulation paths for antifreeze in the engine: a small circulation and a large circulation. Relevant information about antifreeze is as follows: 1. Introduction: The full name of antifreeze should be antifreeze coolant, meaning a coolant with antifreeze properties. Antifreeze prevents the coolant from freezing and expanding in cold winter conditions, which could damage the radiator or freeze the engine cylinder block or cylinder head. 2. Function: It provides anti-corrosion protection for components of the cooling system; prevents scale buildup, avoiding reduced heat dissipation in the radiator; and ensures the engine operates within the normal temperature range.
As an ordinary person who has been driving for over twenty years, I think the normal consumption rate of coolant is really slow, almost negligible. In my daily driving, the fluid level might drop by a few tens of milliliters during quarterly checks, mainly due to minor evaporation in the system or gaps caused by aging seals. There's no need to worry within the normal range, but if you find yourself needing to top it up every two weeks, there's definitely an issue—it could be a radiator leak or a faulty water pump. I always remind myself to check the coolant reservoir when the engine is cold, ensuring the level is between the minimum and maximum marks. Excessive consumption not only wastes money but may also lead to engine overheating, causing serious damage. I recommend monthly routine checks and having professionals inspect it during maintenance cycles to maintain the right antifreeze concentration and fluid level balance. Safe driving is the top priority.
