Default 2007 PT Cruiser Overheating

2007 non-turbo PT cruiser is overheating.

When sitting at idle the temp leans towards hot. Eventually going to Hot if the car sits long enough.
Once driving the car comes back down to normal temp.
Fan is coming on. Coolant is full and I see no leaks.

First time with issues on this convertible. Car has 69K on it.

Any suggestions from the pros here would be awesome.

Welcome to the forum from Pontiac, MI! You may want to go up to the 'Welcome'thread, third from the top, and introduce yourself.

If the fan is working and you are not losing fluid you may have a clogged or damaged radiator. At idle the fan us unable to draw enough air through the radiator to cool the fluid.

A couple of things to do first is visually check the radiator for damage, bent or damaged fins, etc. if you see nothing wrong the radiator may be clogged. Have it reversed flushed and see if that takes care of the problem.

Thank you. I'll google how to do the reverse flush.
I appreciate your answer so quickly.

Welcome to the forum.

You need to first check your radiator fan to see if its working properly. You have two speeds and one of the them might not be working when you are at slow speeds or at an idle.

With the engine cold, start the engine, turn on the A/C and see if you hear the radiator fan come on almost immediately. If you don't hear it come on please don't drive the Pt Cruiser until you find out why the radiator fan does not come on. Manually apply 12 volts to the radiator fan to see if the fan might be faulty. If the Pt Cruiser still has the original radiator fan it might be due for replacement.

A clogged radiator is going to mostly affect the high speeds at the beginning so this is why it's recommended to check the radiator fan first. A high percentage of the time the radiator fan is bad when the engine starts to overheat.

You might want to replace the thermostat if the engine temperature went above the normal engine temperature. They can get damaged when the engine gets overheated and cause more engine damage after repairing the root cause of the overheating.

On my 2007 Convertible Pt Cruiser it is on the third radiator fan due to using the A/C all the time.

If your 07 Pt was mine I would first either check or simply replace the relay #15 in your under hood fuse box.

If you want to know the truth, I would probably replace it without checking it. It's an eleven year old car. I recommend it as a first step because it's easy to do and relatively inexpensive.

If that doesn't cure your problem, then others will have many more suggestions I'm sure.

It's in the upper left hand corner of the box.

Do you have a copy of the Service Manual?

You're probably going to need it, if not for this, at sometime in the future

I would suggest manualy applying 12 volts to the fan with the radiator plug disconnected before replacing parts. Complete diagnostics is important as the more parts you replace the more confusion you put in the process if the new parts are faulty.
