The coolant level warning light will appear on your dashboard when your engine is too hot. This is to inform you that your engine needs to cool down and is at risk of overheating. Below we look at why this may occur and the steps you may need to take.
Why is My Coolant Level Warning Light On?
Combustion engines in cars are driven with a series of controlled explosions that generate huge amounts of heat. Because of this, engines are required to have a variety of passages and a pump that constantly circulates coolant throughout the engine to maintain a safe temperature. The computer in your car is always monitoring the coolant temperature and fluid levels to make sure that the correct temperature is always maintained. When the coolant temperature is too hot, the warning light will be displayed on the dashboard.
What is the Coolant Level Warning Light?
The coolant level warning light usually means that your car is running low on engine coolant, and your engine may be potentially at risk of overheating. A low coolant level usually means that there is a leak present causing it to escape from the engine, which will need to be checked by a mechanic as soon as possible otherwise the problem is only going to occur again.
What Does it Mean When the Coolant Level Warning Light is Flashing?
If the engine coolant light is flashing, this could indicate a cooling system fault. This could mean that there is a sensor fault or a serious problem where the coolant is no longer circulating around the engine. This problem is usually caused by a faulty coolant pump, which will need to be replaced to avoid the engine overheating.
How Does the Coolant Level Warning Light Work?
The coolant level warning light will show up on your dashboard when your car is running low on coolant. Most of the time, this will occur due to a leak that is causing the coolant to escape from the engine. With less coolant circulating around the engine, this increases the risk of your engine seriously overheating while you are driving, which can lead to significant damage. If you notice this light, you may need to book a coolant change or have your car serviced.
What are the Common Reasons the Coolant Level Warning Light Will Come On?
Low coolant levels in your car are most commonly caused by leaks. These can occur either in the coolant reservoir or somewhere in the lines. Coolant leaks can often be a serious issue as they are not always easy to diagnose and can be difficult to fix. Since the coolant travels around the engine, there are various pl
