Cooling System Tech Overflow Tanks Vs Expansion Tanks The cooling system is constantly under pressure with the use of an expansion tank. instead of sending the expanding coolant to the tank once it reaches a certain pressure, the coolant is always cycled through the radiator and out to the expansion tank. here the pressure released from the hot coolant fills the top half of the tank and acts as a. Expansion tank. some manufacturers and websites will confuse the overflow reservoir for the expansion tank, but the two perform very different functions. expansion tanks work in much the same manner as the overflow tank, but server a very different purpose. expansion tanks are just that: tanks that provide expansion of your cooling system.
Differences Between Expansion Tanks Overflow Tanks In Automotive A properly sized expansion tank must have room for 12 percent of the total coolant capacity, plus 6 percent for thermal expansion. so if you have a 13 quart system, you would need 1.56 quarts for drawdown and .78 quarts for thermal expansion. there are a lot of options with recovery tank sizes and configurations. This lower pressure creates a vacuum and pulls the coolant from the overflow tank back into the cooling system via the small valve inside of the radiator cap. expansion tank expansion tanks are a little more complex. pictured is the factory expansion tank from the fk8 civic type r, or the lesser version of the title image. Mcutler1. 1888 posts · joined 2010. #7 · nov 27, 2016 (edited) expansion tank or degas bottle has the only radiator cap in the system. the radiator would be sealed with only lines to the water pump. the tank would be plumbed from the hot side of water pump then to the heater core or back to the cold side, or a t off the heater lines or. An expansion tank is part of the pressurized section of the coolant system. an expansion tank can easily be recognized by the neck and cap used. since the tank is under pressure it will require a pressure rated cap and neck, (shown right). the pressure relief in the expansion tank should be the highest point in your coolant system.

With both devices, coolant will flow into the tank when the engine heats up. the difference, as i see it, is that with the expansion tank, the rad can suck the coolant back out of the tank into the system when the system cools, since the hose between the rad and tank is submerged in the coolant in the tank. with the overflow, the rad will draw. Expansion system: hot coolant can expand within the working system total volume. the working system has a volume of air inside. overflow system: hot coolant expanded but has to flow out of working the system into a separate overflow tank. the overflow tank contains coolant which is not part of a working coolant system.
