Ssshhhhhh!!!!! If you dare mention that you drive a few miles over the speed limit on this forum they have your guts for garters!!!

I concur with Rob you obviously meant 65 !!! other wise you may be blamed with global warming the onset of terrorism andGordon Browns demented lisp. !!!!!!!!!
Is the fan coming on/off, air filter new(ish), coolant not just water,

The radiator tubes that the water flows through could be full of crud, this also happens to the heater matrix.

This normally follows someone sticking a bars leaks pellet in the radiator without breaking it up properly which stops the leaks but can also block the aforementioned tubes.

And of course if the car was used withut antifreeze for awhile (because of the leak) this can also promote corrosion.

Take the plug out of the rad and have a look at the few tubes you can see there.

Dave, do you ever talk on this forum and not just give answers???

At the moment I have a lot going on in my private life and just get on the computer for a few minutes distraction in an attempt to help someone out, why do you ask?

No way pedro!! I am sorry if that's the case but that really is not true. I think it comes from the fact that a thread can lose it's original issue very easily so I try to keep 'banter' if you like to a minimum.

Feel free to have a wind up or a joke ect I'm good for it and as long as you have broad shoulders there's no problem.

Oh by the way, a mate of yours sent me a picture of you recently and thats a great shirt your wearing..........I had one just like that............it didn't fit me either!!
