Blackie mate can't beleive you ain't sorted this problem yet, pull your finger out Nah mate messin i had a similar problem but mine was coured by fitting a brand new radiator for a fiesta si (alloy) £23 1x 10" spal fan new coolant and she runs a dream around town temp is 'O' on the temp gauge and on the motorway between 'R' and 'M'.

EDIT*** I REMOVED THE COOLENT PIPES FROM THE TURBO SO ENGINE TEMP HAS GONE DOWN FROM THAT, AS YOUR ENGINE WILL RUN COOLER AS YOU HAVEN'T GOT TURBO BOILED WATER PASSING THROUGH THE ENGINE.

The main problem with mine was the size of the standard rad its pants, try a bigger rad, xr2i conversion.

If you want pics i can post some for you mate.
