Why is no coolant in radiator but reservoir tank is full?

Consequently, we will concentrate on the signs of no coolant in the radiator but the reservoir tank is full, the causes of lack of coolant in the radiator when there is a full reservoir tank, and the ways to fix this issue. Note that this article is focused solely on liquid cooling systems.

Where is the coolant reservoir in a car?

The coolant reservoir in your car is a plastic reservoir that is located in your engine bay. 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.

When does the coolant go back into the radiator?

It maintains a pressure when the radiator is hot, but also has a secondary valve that is blocked when the radiator is pressurizes, but opens when the radiator pulls vacuum to let the coolant from the reservoir go back to the radiator. If the coolant is dirty, the secondary valve can get plugged.

How does a liquid cooling system work on a radiator?

It includes; the radiator, which is mostly an aluminum radiator, the thermostat, hoses, water pump or coolant pump, a radiator cooling fan, heater core, bypass system, head gaskets, and few other components. The liquid cooling systems function by transporting the coolant through a passage in the engine blocks and heads.

What does it mean when your coolant reservoir is full?

If your coolant reservoir is perpetually overflowing and full, it means that there’s something stopping the coolant to return. This is a sign that one or two of your hoses are leaking. Or even worse, your radiator has a hole somewhere. And lastly, a bad radiator cap can also cause this problem.

Do you add coolant to the radiator or the reservoir?

If your vehicle has a reservoir, the coolant should be added directly to the reservoir instead of the radiator. Except in a case where you have an empty reservoir tank, then you can add the coolant directly to the radiator but consequently top the radiator through the coolant reservoir.

What does it mean when there is no coolant in the radiator?

Signs of no coolant in the radiator, but the reservoir is full. These are some of the common signs you are going to experience when there is no coolant in the radiator of your vehicle irrespective of the fact that your reservoir tank might be full:
