When to use an expansion tank in a cooling system?
An expansion tank is designed so there is space in the tank for the coolant to expand. If an expansion tank is overfilled it will discharge coolant when the system is at operating temperature. An expansion tank can also be used as a fill point for the system.
Where can I find oil in coolant expansion tank?
Alright had a car on the regular auction site that everyone uses, and the final bid goes to a new user which has only created the account a couple of days ago (this should have already sent alarm bells ringing already). The chap rings me (broken English) and discuss details collect the car.

Why does the coolant go into the overflow tank?
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.
