If a coolant leak happens longer, it will be translated into a low coolant level. For example, if you look at the reservoir on your engine compartment that holds the equivalent, you'll see that the coolant is sometimes dropping below the minimum point.
4. Temperature fluctuations
Since the temperature gauge on the dashboard is responsible for monitoring the engine temperature all the time, you'll also notice some fluctuations in the reading, which is inconsistent all the time.

2. Turn off the engine
You need to turn off the engine once you're in a safe area and allow people to see you by using some triangles or turning on the hazard flashlights. This allows you to control the problem and prevent it from worsening.
3. Allow the engine to cool down
Before you touch the cooling system, you must leave your car to cool down for at least 30 minutes to an hour in some instances. This is because the cooling system will be very hot, and touching it at this point might lead to some hazards of getting burned.

6. Tighten the holes
If you notice some connections you need to tighten, try tightening them and see if this resolves your problem. However, if the problem is related to a broken seal, it could be out of your hands.
7. Check for damages
You also need to check for any potential damages within the cooling system. Sometimes, you might see a broken seal or even more major damages that cause your coolant to leak outside the car.
