Unhappy Overheating problem !!

Hi All,
I am new here so sorry if this has been asked before, i am having problems with my 06 PT.
As the title suggests i am suffering with overheating problems.
I will try to mirror what happens and what i have checked so far.
Ok, after driving for a short while the engine gets up to working temperature and the gauge sits in the middle like it should, whilst driving there seems to be no problem however when i stop you can hear the water boiling, when opening the bonnet i can see the water boiling up in the expansion tank and overflowing out onto the floor.
i have checked the fuses to the fan, there are no water leaks, the radiator cap and filller neck are fine, i have run my OBD2 code reader and get no codes found back, in fact i can't see anything wrong.
i will say however i have not heard the fan come on once
Can i test the fan in anyway?

Any help would be great please

Welcome to the forum. I would suggest you introduce yourself and say a few things about your PT Cruiser.

I would suggest you stop driving the PT Cruiser until you find out why the radiator fan is not working. .

First thing you need to do is manually check the low and high speed on the radiator fan by manually applying 12 volts. With the engine cold try starting the engine, turn on the A/C and see if the radiator fan automatically comes on.

Post what you find out.

Also, when you say the radiator cap is "fine", is it new? Did you do a pressure test on it?

When you say "overheating problem", is the temperature gauge going above 3/4 or into the red or is your symptom the "boiling water" into the tank?

...and welcome.

Hi, and thanks for the welcome, i did post a newbe message already.
I am no longer driving the car. On you advise i checked to see if the fan came on when using the A/C as you described and it didn't.
I am now going to check for power at the connector ( Well if it ever stops raining that is.) I will also try adding 12V diredtly to the fan and see what happens. I will post my results later.

Hi Thanks to all for the welcomes....
Yes the cap is new, also there are no leaks or steam anywhere.
No the temperature gauge is sitting at half way, it has never gone higher.

Why did you get a new cap? Has there been any work done to the cooling system?

My car had some fairly severe chugging and bubbling in the overflow after shutdown when it had air pockets, but I don't think that would just happen out of the blue. I figure you had something going on to swap caps, so maybe you changed the coolant?

I didn't get a new cap, i bought the car recently used and the cap was already on it...i have no idea if any work has been done to the cooling system.
The car was running fine for a few weeks and the problem has only just started.

Then why do you say that the radiator cap is fine? Did you test it? It is possible that it has just been overfilled, but that might be among the least likely options.
