Motorsport developments sell a uprated fan switch and 82 degrees thermostat

Fit these along with a brand new "genuine ford" coolant temperature sensor, this and a good service is all I would do

Most of the time they have had repairs and poor quality components have been used causing it too either run hot or "appear" to run hot on the gauge

Also check what year/ mileage the cambelt kit was changed, as they degrade by age as well as mileage, and while your there if it needs it fit a new water pump


These things on a standard car should have it running nice and cold

Then alloy rad and fan kit, and intercooler upgrade is only needed if upping the power

Enjoy mate, I have been messing with them for 10 years now lol
