What can be causing my 2008 Saturn Aura Xe 3.5 to overheat? READ DETAILS PLEASE.

What is your question?

Replaced the radiator and after a week or 2 it started overheating though it was the thermostat replace that and its overheating even faster than before and it made a bubbling sound after putting some more coolant in. No leaks at all and after radiator replacement is sucking up all the coolant but still no leak

How long has your 2008 Saturn Aura had this problem?

Overheating- 1 week
