running hot, not overheating

As a check to see what your coolant temp actually is you could replicate something I set up recently with the Torque Pro app.
Configure the 'engine coolant' PID on a screen and in the settings there is a configuration to set the polling interval of all PID sensors.
I've been doing this to try to figure out why my car is over-cooling.
I wanted to configure the oil-temp too but this isn't available via OBD sadly. It's on the canbus I think.

It could be useful for you to confirm if it's not just a faulty sender giving weird fluctuations by having a second temp readout to collate the data in real time.

Ok so I checked the fan out and it appears to be running correctly , as the motor warms up it turns on and then slowly increases speed. If you turn on the A/C it jumps into turbo mode.

And.. the car once running in slow traffic still gets hot and then will cool down with no apparent change in the fan speed (ac running). Starting to think its the radiator....

Also Chris_d can you please tell me whats involved in the Torque set up? Is it similar to Carly?

Thanks all!

I've got Torque Pro, you download it from your mobile app store, pay a couple of quid for the pro version and you will need an OBD2 dongle from ebay/Amazon etc for about £10 for a decent one. It plugs in under the dash. Follow the set up on the screen with bluetooth switched on and you are up and running.

WHen trying with car static, and watching fan, which you say ramped in speed - did the needle move ( a/c OFF ) up and down then ?

What ewazix said.
Useful for me to see it fluctuating between 70-80 where it should ideally be constant 90-95.
You will also be able to record a diagnostic session, complete with map and speeds for later analysis.
Good luck

So there is a clue, ONLY with the A/C on does this issue occur

Interesting though as from my understanding the A/C have nothing to do with the coolant or path it takes ? Just the fan is on faster than it might be. So why your temp sensor reads up is strange when its on
 
Baffling, I am home now and from cold watched the car warm up, at no time did the fan come on...however the needle was dead center the whole time. I drove it around the block and still no fan...

At what temp does the coolant have to be for the fan to come on?
 
lets be clear here.. are you saying it ONLY gets warm when the ac is ON ?

the ac and the engine fan work for different masters, both have temp sensors and are independent of each other, it seem likely one of the sensors is faulty/give a bad reading, shorting each one should make it come on.
the sensors are pre set of course.
