Is there a radiator cap or just overflow tank?
The radiator pressure cap is the unsung hero of your cooling system and works in unison with your overflow tank. Many people think that your radiator cap is simply a screw-on-lid for your radiator, but it’s so much more. Inside your radiator cap is a spring loaded valve.
How to find where my radiator is leaking?
Why is my radiator leaking?
- Parts of the radiator are damaged
- Loose radiator pipe joints
- Corrosion caused by a build-up of debris during installation
- Corrosion caused by air being drawn into the system
What is the purpose of a radiator overflow tank?
- Make sure the engine is cold.
- You can either drain the cooling system first by opening the coolant drain plug or disconnecting the lower radiator hose (if your car doesn’t have a drain plug) or pinch ...
- Remove the nuts and bolts that keep the tank in place. ...
- Afterward, remove the lower overflow tank hose. ...
Where does the radiator overflow tube go?
An overflow hose connects to the radiator below the cap and the reservoir tank to store overflow of coolant. As pressures in the cooling system increase due to coolant temperatures, a valve on the radiator cap permits coolant back into the reservoir to help ease the build-up of pressure and prevent coolant loss.

Does my radiator need an overflow tank?
In terms of overflow you do need one. Radiators will cool and heat dependant on how hard you are working the engine. Additional heat means the fluid expands and pushes water out the overflow, cool and it'll try and recover some of that water.
Where do you mount a radiator overflow?
Choose a mounting position for the overflow tank. Be sure that there is enough room to connect a hose(s) to the bottom of the tank without interference from any other components. It is recomended to use the side tank of your Flex-a-fit radiator to mount the overflow tank.
How does a radiator overflow tank work?
The radiator coolant overflow tank works by filling the tank with coolant when the cooling system's pressure is too high and withdraw coolant from it when there is under pressure in the system. The coolant is transferred back and forth between the tank and cooling system depending on the pressure.
Does a coolant overflow tank need to be higher than the radiator?
Since the radiator is lower than the engine a pressure relief and fill point that is higher than the engine is needed. This is accomplished with an expansion tank. When the radiator is high enough to act as a fill point and pressure relief an expansion tank is not necessarily required.
Will a car overheat without a overflow tank?
tl dr; Not directly, but yes. The purpose of a recovery or overflow tank is to allow for expansion of the coolant, then to recover it back into the radiator as things cool off. If the tank is not there (or it all leaks out), the radiator is pushing it out onto the ground without the ability to recover any of it.
How does coolant flow from reservoir to radiator?
To do its job, the coolant moves in a continuous cycle, pushed through the engine by the water pump. The engine contains internal hollow structures called water jackets. The coolant flows inside the engine through these, absorbing the engine's heat. It then travels through hoses to the radiator, where it cools down.
Why is my radiator full but reservoir empty?
When the overflowing coolant reservoir does not return to the radiator the hot coolant that needs to be cooled down, means that there might be a leakage or clog of the radiator hoses that allow the flow of fluid from the coolant reservoir to the radiator. It can be a result of a damaged radiator cap.
What size radiator overflow tank do I need?
The general rule of thumb for proper capacity of expansion is 12% of total coolant volume for draw down and 6% of the total volume for thermal expansion. Drawdown capacity is the amount of coolant that can be lost before air reaches the water pump and is introduced into the system.
How much antifreeze should be in the overflow tank?
The coolant overflow tank is made to hold the coolant in reserve to adjust for engine temperature and altitude variances. You need to have at least 30% of the tank full to safely operate your vehicle, but it can be just as bad to keep the tank too full.
How does a coolant reservoir work?
As it passes by the engine picking up heat, the coolant expands, backing up into the reservoir. As it releases that heat in the radiator, the coolant contracts, leaves the reservoir and returns to the engine.
How does a radiator overflow tank work?
The radiator coolant overflow tank works by filling the tank with coolant when the cooling system’s pressure is too high and withdraw coolant from it when there is under pressure in the system .
Why does the radiator cap open?
As the coolant temperature increases and the pressure inside causes the coolant to expand, the valve inside your radiator cap opens to allow the excess coolant to flow into your overflow tank. This valve allows your cooling system to stay pressurised but will help prevent the system from over pressurising and thus overheating.
What happens when coolant is overflowing?
As the coolant begins to cool, it contracts and increases the amount of room once again inside the cooling system. This contracting of the coolant creates a negative pressure which draws the extra coolant stored in the overflow tank back into the primary cooling system. Therefore, your overflow tank is used as an expansion vessel to allow ...
What is a radiator pressure cap?
The radiator pressure cap is the unsung hero of your cooling system and works in unison with your overflow tank. Many people think that your radiator cap is simply a screw-on-lid for your radiator, but it’s so much more. Inside your radiator cap is a spring loaded valve.

How does a car cool off?
Your vehicle’s cooling is simply designed to cool the engine by carrying it’s generated heat away. As your engine turns over and gets hot, the coolant that passes through and around your engine steals this heat away and carries it to the front of the car where it’s cooled off by the radiator and cooling fans.
Why do we need an overflow tank?
This is the reason why we need to have an overflow tank as the pressure inside the coolant pipes increases due to the coolant solution being heated and therefore expanded. The expanded coolant needs somewhere to go. Any liquid that no longer fits inside the primary cooling system is now forced into the overflow tank, ...
Why does my exhaust glow orange?
The cooling system. As you’re probably already aware, your engine gets incredibly hot as you drive. So hot in fact, that it can cause parts of your exhaust to glow bright orange! So your car needs a system in place to provide an efficient means of cooling.
Step 1 - Preparations
- Now that you have the tools in hand it is time to remove the old radiator overflow tank. Release the hose clamp and pull firmly to unplug the reservoir from the tank. Then turn the mounting bolts counterclockwise to loosen them. If you have an elongated tank, look for bolts that may be hidd…
Step 2 - Removing The Old Reservoir
- Pull the old radiator overflow tank free to remove it. Sometimes you will find the computer to the car on top of the reservoir. So carefully set aside the computer to remove the reservoir. This is true for General Motor products.
Step 3 - Putting in The New Tank
- You can now put the new tank in and position it so that you can secure the bolts, but do not over tighten them. If the bolts are over tightened they can split the tank. The bolts tighten clockwise.
Step 5 - Replacing The Computer
- Once the new tank is in place, gently replace the computer and any other engine components that were removed. The mounting bolts will be turned clockwise and then you can plug the adapter back in securely.
Step 6 - Finishing Touches
- Be sure to check the proper levels of fluid in the tank before you go to refill it. The tank is equipped with an open vent cap. This releases pressure as it opens to allow the coolant to expand. As the coolant expands, the fluid is forced into the tank by the lower hose, thus forcing air to escape into the tank. This will allow the cooling system to expunge the air which will cause lowering the cool…
