Hi Roger,
I live in Dubai and its 47C outside, I am not saying I am not having problems but as a start...
Change your Thermosat to one that open a lot sooner like a 74C Thermostat.
Secondly drain your coolant and flush the system and add Red Line Water Wetter x 2 bottles along with the cooland/water mix.
Not 2 sure about the condiation of your belts..
Lastly check your fan switches relay as mine was faulty.
Good luck,
Regards,
Ahmed
