Radiator Overflow Tank
A Guide to Installing the Radiator Overflow Tank Correctly
Basically, the radiator overflow tank's job is to guide the coolant fluid, which contracts and expands in the car. The tank is a transparent white plastic container that's found just near the radiator fill cap. If this gets busted, you'll have to get this replaced with a new one right away to avoid any leaks or problems that could possibly harm the coolant system. Installing this can be simple if you keep these steps in mind.

List of tools:
Getting ready for the task
Before doing the job, you'll have to take out the old radiator overflow tank from the car. This will entail you to let go of the hose clamp and to pull it really hard to unplug the reservoir. Once you find the mounting bolts, loosen them up by turning them clockwise. Take note that if you have an elongated tank, you'll have to locate the other bolts that are hidden. After, you can take out the old tank; if you find a computer, then you'll have to set this aside.
Installing the new tank
Once the old tank is out, you can safely install the new radiator overflow tank. Put it in position so that you can place the bolts. Be careful not to tighten them too much because this can cause the tank to split. To connect the new tank, attach it to the nipple and carefully tighten up the hose clamp. You'll have to either pinch it or screw it, depending on the kind that you have.
Replacing the computer
If you've securely installed the radiator overflow tank, you'll have to get the computer back as well. Be sure that you turn the mounting bolts clockwise and plug the adapter right back on.
Capping it off
For the finishing touches of the installation process, fill the tank with proper level and mixture of coolant. Take note that the tank comes with an open vent cap, which releases pressure while it opens for expansion of the coolant. As this happens, the fluid goes back to the tank and forces the air to exit. This is a sign that the radiator overflow tank is working correctly.
