Changed thermostat, water pump and had head gasket done but still overheating. Water appears to be circulating properly, any ideas what else could be causing her to overheat?

Is the fan working?

Yes, kicks in just before it tips into the red and brings it back down to about 3/4 on temp gauge. Since having new thermostats (its had 3 lately) temp gauge sits middle to 3/4 up whereas original one never moved from the cold unless on the rare occasion sat in tonnes of traffic. Totally confused with whats up.

Try the original one see what happens

Unfortunately no longer got the original one, although the one thats in now is a genuine part 

Did you check the head for cracks? Silly question I know but we all forget to check these things sometimes. Believe me I have lol

Yes no cracks

I would try changing the Temp sender for a new one in case that is giving false readings. Cheap and worth a try seeing as you had the major things done already.

Thanks guys

Have you changed the expansion tank cap. If its not holding the pressure it will give the same symptoms of a head gasket failure. It will also boil at a lower temperature.

Thanks for the help, i'll give them both a go and see how i get on
