u seem to have changed everything but your radiator?

Is the fan working?

[rmalov]

the radiator isnt blocked its fine, the fans are working fine, the tacho says its overheating but the car is not boiling over, my mate seems to think its some regulator or something thats behind the tacho? could it be this? even thou the sensor is working perfect could it stil somehow be the tacho showing the wrong temp?

Its not a prelude but check everything that has been posted and see if it applies to your situation

It could be the coolant temp sensor, most likely thats the problem if the car isn't actually overheating
