What to Do When Car Coolant Is Insufficient?

[LeJulianna]

When the car coolant is insufficient, it should be appropriately replenished. Insufficient coolant cannot effectively cool the engine, which may accelerate engine wear in mild cases and potentially lead to engine burnout in severe cases. Below is a partial introduction to coolants: 1. Alcohol-based coolant: Uses ethanol (commonly known as alcohol) as an antifreeze. It is inexpensive, has good fluidity, and is simple to prepare, but it has a low boiling point, is prone to evaporation, has an easily elevated freezing point, and is flammable. It is gradually being phased out. 2. Glycerin-based coolant: Has a high boiling point, low volatility, is non-flammable, non-toxic, and has low corrosiveness, but it is less effective at lowering the freezing point and is costly. Only a few Nordic countries still use it.
