A red engine coolant light warns the driver of two potentially serious problems: a low coolant liquid level or a high coolant temperature.

Both of these problems are very serious; therefore, stopping driving and turning off the engine immediately is necessary. Otherwise, there is a risk that the engine will start to overheat, as a result of which it may even seize.

Red symbols on the dashboard, unlike other warning lights, indicate a serious problem that must be solved immediately. If you ever find yourself in a situation where a red warning light comes on, don't ignore it!

It can be an applied handbrake, an opened trunk or door, low oil pressure, or engine overheating. In any case, you should pull over and, if possible, solve the problem. Every minute counts, and if you don't want to risk damage to the engine or other components, you must act.

The engine coolant warning light can have two functions, more precisely, a warning and an informative function. Beware that there may appear two coolant warning lights on your dashboard.

The first one is blue and has only an informative function, while the red one warns of a serious problem.
