Overheating and overheated!

Asked by Aug 13, 2017 at 05:08 PM about the 2007 Chrysler PT Cruiser GT Convertible

Question type: Maintenance & Repair

'07 PT Cruiser. Stuck... I think I tried all the small
stuff... Flush, thermostat, fuses and fan. However
my radiator keeps losing coolant which causes it
to overheat yet there are no leaks on the ground
nor is there any coolant in the oil. What do I do
from here?

Pressure test system and make sure there is no air in system. Coolant does not get used only circulates. If you are refilling you have a leak somewhere. Internal or external.

Thank you Guru9FSV8. I failed to mention the pressure test I had done in January. Once the weather turned warm, the issue returned. After 4 mechanics who either thought it was one or another thing, I brought it to one more mechanic this week. He found coolant outside and on top of the radiator. Needless to say, I agreed to replace it. However, once he took it AND the fan out, he found the fan wasn't working. It kept shutting off when it was suppose to turn on. I'd like to say here. I thought it was the fan from the very beginning. I had 2 mechanics say it was fine. But I wasn't convinced. I should have stuck with that diagnosis. Regardless. Now I have a new fan and radiator as of today. I'll be testing it this weekend. Fingers crossed.

Fans are very easy to test for the future. Take 2 leads with alligator clips and disconnect the pigtail of the fan and connect these two wires, one to each contact. Next put the ends on the battery terminals. The fan should immediately turn. It does not matter on the polarity. It is a DC motor and will turn based on connectivity. All you are wanting to see is that they run.
