rite i have a 90 2wd saff cossie stage 1 chip standard intercooler standard rad etc, but my temp gauge goes the whole way 2 the white line beside the red boilling point.... before the fans cut in... yes above the n and o of norm on the gauge but the car is not running that hot ive changed fan switch, water temp sender, clocks and have a air charge sender and temp transmitter on the way from uk has anyone ever had this problem as its scary to look at when driving but the car drives fine even in traffic with not a hint of over heating

 

If it is not overheating and fan cutting in and out then it is just the guage.
Mine, 2wd sapph has a mind of it's own too, and regualarly hits the red and beyond before fan cuts in, sits for hours in traffic though, next day it could be on bottom of scale before fan!
I measured my temps and they were nothing like the guage was suggesting, best thing I ever did was to take off the sheild between rad/intercooler from front air flow!!

Or, there may be an earthing problem somewhere - it is a Ford after all

The temp sender (as you know) has a single wire that pretty much crawls straight back to the instrument cluster. As you've changed the clocks already, and have 'second opinions' on the water temp, you probably have a wiring fault somewhere in the wire from the sender to the clocks.

 

Just earth the wire on the engine to test if guage reads full, right over the red and beyond till it can read no more, some people do not even have them connected!!
