FAQ:
Q: What is an overflow tank in a vehicle for?
A: The overflow tank is connected to an overflow tube that comes from the radiator. This tank provides extra storage space for coolant as it expands when the engine heats up. Without this extra overflow storage space, the coolant would expand and run out from the overflow tube and onto the ground.
Q: How does the overflow tank work?
A: An overflow is directly related to the pump you run to move water from refugium/sump/resivoir back to the main tank. The overflow also acts as a skimmer helping to create a constant water surface change to allow better O2 exchange.
Q: Where does the water go from the overflow tank?
A: An overflow pipe leads from a water storage tank or cistern inside your home to the outside . They’re a vital part of your home’s plumbing system. If the water in the tank or cistern fills up to a higher level than it should, the excess water flows down the overflow pipe and runs outside, rather than leaking into the room.
Q: Why does the coolant go into the overflow tank?
A: As the pressure causes the coolant to get higher than the radiator pressure cap, the excess coolant needs to be captured somewhere in order to prevent leakage. So, the radiator coolant overflow tank functions to serve this exact purpose. The excess fluid flows into the overflow tube and goes into the overflow tank.
