![]() One option you might like in terms of an upgrade isn’t related to size. You’ll also need one that fits all the stock mounting points and hose connections. So, you’ll need a radiator overflow tank that accommodates the size recommended by the vehicle’s manufacturer. The cooling system and the expansion tank are matched so that they will work well together. What Size Radiator Overflow Tank Do You Need?Ī standard radiator overflow tank’s design is fairly specific to a given vehicle. The excess pressure opens a valve, allowing some of the fluid to escape into the overflow tank, preventing a rupture in the cooling system and keeping all the gas and fluid inside of the cooling system. Since the coolant fluid has expanded as it grew hotter, it no longer all fits inside of the radiator and tubing. The radiator overflow tank works by allowing the excess fluid to vent out of the primary cooling system. How Does the Overflow Work on a Radiator? Modern cars require an overflow tank or some sort of expansion system to accommodate the excess pressure without leaking coolant to the atmosphere or dripping it onto the ground, where it could hurt curious animals, people, or the environment. It’s also sweet, so animals might taste it and become sick or even die. After all, coolant, also known as antifreeze, can be quite toxic. That kept the system from exploding when it got hot, but it created pollution. Instead, the cooling system had a vent or multiple vents that allowed extra pressure to escape the system. Before working on a radiator system, you have to understand the layout of all the components and how everything fits together. Note how all the hoses connect the radiator and overflow tanks to the engine, the water pump, and other vehicle components. If you’d like a more detailed look at a design from a real car, this schematic from a mid-90s BMW 3-Series shows the radiator in the lower-left corner and the radiator overflow tank just to the right of it. That captured fluid then flows to the overflow tank.Ĭheck out this simple diagram to better understand how a typical cooling system works with a radiator overflow tank. Typically, a tube near the radiator’s cap collects the expanding fluid that doesn’t fit inside the primary cooling system. The radiator overflow tank lives near the top of the radiator. Where Is the Radiator Overflow Tank in a Car? A radiator overflow tank allows the pressurized cooling system a little bit of extra room so that when the heated fluid expands, there is enough space for it, and nothing overflows or breaks. When the fluid in the cooling system gets hot, it expands, just like when a pot of water on your stove at home gets hot and overflows. By the time the fluid cycles through the radiator, a portion of the heat has dissipated. The cooling system on a car uses fluid to transfer the engine’s heat to a radiator, where fresh air interacts with the heated fluid. ![]()
