This problem can drastically reduce the functionality of the vehicle due to engine poor performance. It can be due to a faulty radiator or a bad thermostat or even other related issues. It is a very common sign that reflects that something is wrong with the cooling system. It could be as a result of lousy thermostat, bad radiator, and other related cooling system parts.

However, other factors can cause issues in the cooling system. Once the reservoir gets filled, the rest will waste through the overflow outlet. If a head gasket blows, the combustion gases from the cylinders will leak into the cooling system and push the coolant into the reservoir.

The common reason for no coolant in radiator but the reservoir is full is a blown head gasket. Signs of No Coolant in the Radiator, but the Reservoir is Full. Immediately the liquid is cooled, it flows back to the engine to reduce its temperature.

The heated coolant moves through the thin tubes in the radiator, and it is cooled by the airflow toward the engine compartment from the car’s grill. The coolant is heated and then flows to the radiator through a rubber hose. The coolant picks up heat as it passes through the engine. The liquid cooling systems function by transporting the coolant through a passage in the engine blocks and heads. So, 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. 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 a few other components.

The liquid cooling system of a vehicle consists of various components. Note that this article is focused on liquid cooling systems. Though, it is uncommon to see a vehicle manufactured with an air-cooling system. Vehicles can either be liquid-cooled or air-cooled. The engine cooling system plays a very important role in the efficient operation of the engine.
