What to Do When Engine Coolant Is Insufficient?

[OwenMarie]

Add coolant. Below is a detailed introduction on how to add coolant: 1. Reasons for insufficient coolant: Low coolant level is caused by the thermal expansion and contraction of the coolant. If the outside temperature is low enough, the contraction will be more severe, causing the level to drop below the standard minimum line and trigger a dashboard warning. Thermal expansion and contraction of coolant is a very common phenomenon and occurs in almost all vehicles. 2. Precautions: Do not mix different coolants. Different types of antifreeze should not be mixed. This is mainly because most coolants on the market are ethylene glycol-based. Even if they are from the same manufacturer, non-ethylene glycol-based coolants should not be mixed. If you need to replace the coolant, it is best to flush the system clean before adding new coolant.
