The indicator says my car is overheating.
Overheating can be caused by many things. Low coolant is the most common one. I would start by making sure the coolant level is appropriate. A bad thermostat, air pocket, or a fan that is not coming on when needed can also cause the vehicle to overheat. A mechanic, such as one from YourMechanic, can perform a pressure test to determine if there are any leaks in the system and diagnose your overheating issue. They can also test the fan if it is coming on at the correct temperature and the thermostat is opening properly. I advise you not to drive the vehicle until the overheating is corrected. Overheating an engine can cause secondary internal engine damage.
