My son has a 2006 PT Cruiser and he was having the same overheating problem. After replacing almost everything, we found out that we could only use the factory radiator fan. We initially replaced the radiator fan with one purchased from Advance Auto, but it was still running hot. After replace the radiator fan with a factory radiator fan, he hasn’t had anymore problems with it running hot. I hope this helps someone.
