Ford Coolant Tank: Hold Your Ford’s Coolant Efficiently w/ Ford Coolant Reservoirs

Any vehicle would need fluids for it and its parts to function properly. Among the more common fluids that are used in vehicles are fuel (which may be gasoline or diesel), lubricant oil, brake fluid and coolant. Inside your vehicle, all these fluids have their own container on which they will be stored before they are used. All types of fuels are stored inside the fuel tank while the lubricant oil is stored in the oil pan and the brake fluid in the master cylinder reservoir. The engine coolant, while it is meant to flow continuously through the various parts of the engine, must also have a container. And in your Ford, this container is the Ford coolant tank.

The coolant tank is a semi-transparent plastic tank, which may be pressurized or not, that is used for storing the coolant before it is transferred to the radiator. But what would you need the tank for if the coolant is continuously flowing through the various parts of the cooling system? The coolant tank is also known in various other names. It is often called the coolant reservoir, coolant expansion tank, coolant recovery tank or coolant overflow tank. These alternative names should be enough to give you a hint of what the coolant tank is really made for.

Coolants, by nature, have a tendency to expand as temperature rises. As the engine gets hotter, the coolant in the radiator would normally overflow and it is the function of the coolant tank to hold this excess coolant. As the cooling system cools down, however, this coolant is drawn back to the radiator and out of the coolant tank.

Aside from serving as a container for the expanding coolant, the coolant reservoir also makes checking the cooling system fluid level a lot easier and safer. Coolant tanks are usually marked with two indicators on their side, one for the safe fluid level when the engine is hot and the other when the engine is cold. In modern vehicle systems, the coolant would even be used for another task—that of adding coolant to the system which would formerly require the removal of the radiator cap.
