Hi and thanks for using 2CarPros.com.
I am not sure what component was replaced. Let me know. Also, many things can cause an engine to over heat. Components such as a thermostat, radiator, head gasket, faulty radiator cap, plugged radiator, cooling fan issues, low coolant can all lead to a problem. Take a look through these links that discusses the different components.

Here is a link that shows how to check for a bad head gasket:

As you can see, there are many things that can cause it to over heat. If you could, tell me if it only happens when in stop and go traffic, if it starts leaking from the overflow when first started or soon thereafter, if there are any leaks, if the radiator cap has been replaced.
Anything you can think of that may help me diagnose the issue may be helpful. Also, let me know if the component replaced was the reservoir itself and if it was done by someone trained in bleeding the system.
I will watch for your reply.
Take care,
Joe
