What does it mean when your coolant reservoir is full?

When the overflowing coolant reservoir does not return to the radiator the hot coolant that needs to be cooled down, means that there might be a leakage or clog of the radiator hoses that allow the flow of fluid from the coolant reservoir to the radiator. It can be a result of a damaged radiator cap.If your radiator is empty but your coolant reservoir is full, it can mean that there is one or more than one problem with the components of your engine cooling system. This will mean that there is a possible fault in the radiator or your radiator hose. You might also have a damaged gasket, a damaged radio cap, or some damage to other components.

Why is my coolant reservoir full but my radiator is empty?

If your coolant reservoir is full but your radiator is empty, there might be something wrong with one or more in the components of your engine cooling system. There are a lot of possible things that you can do, you just have to know the reason for it.

What does a coolant reservoir do?

It’s responsible for storing all the coolant that your car’s cooling system needs to cool your engine off when your car is turned on. It’s important for your car to have a fully-functioning coolant reservoir in it because your engine is going to need different amounts of coolant at different times.

What happens when a car coolant reservoir boils?

When the fan does not keep the radiator cool, the car coolant reservoir can boil. A failing cooling fan is characterized by overheating the engine and often a loud noise coming out of the radiator fan. If the cooling fan motor fails, its blades stop spinning, and airflow is not generated. How To Fix It?

What do the marks on the coolant reservoir tank mean?

One of the marks denotes the coolant in the reservoir when it is hot, and the other indicates the coolant present when it is cold. Generally, when there is too much coolant in reservoir tank, it gets expelled out through the overflow hose. In case the expelling does not take place, it could lead to potential damages.
