i have a 99 reg fiesta and it overheats after about 15 minutes of 40-60mph driving. the guage goes into the red, the fan clicks on and the coolant bubbles like mad. i have just got the car serviced and had some valve thingy replaced and the problem is still there! the car only overheats when im driving on faster roads so i can still get around in the city... but i cant go beyond 5 miles or so...

please if anyone has any idea what the problem is it would be great!!!
thanks!

Sounds like they replaced the heater valve, there is currently a concern with them causing overheating- other possibilities are thermostat/head gasket/water pump.
