When the fluid in the cooling system heats up, it expands, causing the pressure to build up. The cap is the only place where this pressure can escape, so the setting of the spring on the cap determines the maximum pressure in the cooling system. When the pressure reaches 15 psi, the pressure pushes the valve open, allowing coolant to escape from the cooling system. This coolant flows through the overflow tube into the bottom of the overflow tank. This arrangement keeps air out of the system. When the radiator cools back down, a vacuum is created in the cooling system that pulls open another spring loaded valve, sucking water back in from the bottom of the overflow tank to replace the water that was expelled.
What else can I help you with?
Where is the antifreeze tank in a 1995 Honda Accord or do you just put it in the radiator?
Put it in the radiator but also make sure the overflow tank is full. Follow the overflow tube from the radiator and you will find the tank.
Did the 1965 impala have a radiator overflow tank?
No.
How does the overflow tank work?
if your water/antifreeze gets to hot it pushes out the over flow tube into the overflow container, as it cools down it will suck it out of the overflow and back into the radiator.
How do you refill radiator in a golf GL 1997?
You have to fill the overflow tank as the radiator does not have a fill cap. Run the engine as you fill the overflow tank but just up to the marks on the tank.
What is an overflow tank?
An overflow tank is a bottle that holds coolant that expands and leaves the radiator under driving conditions. The Coolant will go back into the radiator as needed.
What is the difference between a Coolant Overflow Tank and a radiator overflow bottle?
A coolant overflow tank and a radiator overflow bottle serve similar purposes but are distinct components. The coolant overflow tank is designed to collect excess coolant that expands from the radiator when the engine heats up, preventing pressure buildup. In contrast, the radiator overflow bottle typically refers to a specific type of tank that captures overflow from the radiator directly, allowing for the coolant to return to the system as it cools. Both components help maintain the proper coolant level, but they may be used in different cooling system designs.
Where do you put radiator sealant in a 2003 Dodge Intrepid or where is the radiator cap?
the water overflow tank
Where is the radiator cap on a 2002 Chevy silverado truck?
Its on the overflow tank.
Should there be an overflow tank for the radiator on a 1992 Nissan Sentra?
yes
What is the white container connected to radiator?
coolant overflow/reservoir tank
Where is the top radiator tube located in a 1999 Oldsmobile cutlass?
You fill the radiator through the overflow tank.
Where is the antifreeze tank in a 1992 Honda Prelude?
there is an antifreeze overflow tank, look on the radiator next to the radiator cap and there should be a smallish hose, follow it and you will find the tank.
