Hello guys,

I have purchased 07 XF few weeks ago.
car was running fine, I haven't touched anything yet.

Today when I was driving on highway w some traffics, I have noticed temp gauge was reaching slightly over 50%, which usually stays around 46~8%. I turned on A/C on then I heard fan running and temp went down to normal. I wasn't sure so I tested few times, temp was keep trying to rise if I turned a/c off.

So... heres some Qs need to be ruled out..
1. Does XF uses 2 fans? 1 for cooling, 1 for ac?
2. Assuming XF is using 1 fan, and if fan runs on AC, it means fan and fan module or fuse is all fine.. then what could the problem be?
3. No warning lights lights are on, connected reader to see if there's anything pending, nope.

Please helppppppp
Thank you!
