What should you do if your car’s Overheating light comes on?

What should you do if your car’s Overheating light comes on?

Many cars have an engine overheat warning light on the dashboard to alert the driver of an overheating problem. Some cars have blue and red lights, while others have green and red lights. When you start the car, it will display a blue or green light because the engine has not reached a sufficient temperature. The blue or green light should dim when the temperature is reached. This is completely normal for a car with a functioning engine. If your car’s temperature indicator light turns red while you’re driving, it means your engine is overheating.

Car Overheating problem

What should you do?

Check the following items to determine the source of the engine overheating.

  • 1. Inspect the radiator to see if it is broken and if there is any water in it.
  • 2. Examine the water pipe for any leaks.

This is only for the process of locating issues for quick self-repair in an emergency situation. You should have had it inspected by a mechanic if you can’t see the problems mentioned.

What causes a car to overheat?

There are numerous possible causes of car overheating. The most common cause is a thermostat malfunction. The thermostat controls the flow of coolant through the radiator, and if it fails, the coolant cannot do its job. A radiator leak is another possible cause. A leak can allow coolant to escape, causing the engine to overheat if not repaired. Furthermore, the radiator fans may be malfunctioning. These fans circulate air around the radiator, which helps to keep the engine cool. If they fail, the engine can quickly overheat.

Pull over in a safe location as soon as possible and seek professional assistance. Drive safe!
