What is the symbol for insufficient engine coolant?
2 Answers
When the engine coolant is insufficient, the water temperature warning light will display a thermometer shape, and there is also a kettle-shaped symbol. The functions of antifreeze are as follows: 1. Cooling effect: Cooling is the basic function of coolant. The engine generates a large amount of heat during operation, with 60% of the heat being dissipated to the surrounding space through the cooling system. Water and methanol coolants have low boiling points and are prone to boiling. If the vehicle operates under conditions where the coolant is boiling, even for a short period, it can cause engine damage or even complete failure. 2. Anti-scale effect: The coolant should minimize the formation of scale during circulation to prevent clogging of the circulation pipes and impairing the heat dissipation function of the cooling system. In summary, one should be cautious when selecting and adding coolant.
I learned this from my driving school instructor: The warning light for insufficient engine coolant looks like a thermometer floating on water, usually flashing yellow or red. When this light comes on, you must pull over immediately to check, or the engine can overheat and start smoking in no time. Once, I encountered this situation on the highway and found that the radiator hose connector had aged and was leaking, causing all the antifreeze to drain out. A reminder to all car owners: not only should you recognize this warning symbol, but it’s also best to keep a small bottle of antifreeze in the trunk for emergencies. Especially before long trips, remember to open the hood and check the coolant level in the overflow tank—it should be between the MIN and MAX marks to be safe.
