   have you bled it properly? Is the water pump ok? Could be the head gasket is gone and the system is getting pressurised and cooked.

   Let the car warm up buddy and then check the coolant top and bottom hose, you might have a blockage on either the hose's or the new rad itself

   Flush the cooling system through until clean water comes through.

   got to make sure it flushes through all the pipes including the heater matrix as mine was blocked by the heater matrix
   
   as said let it heat up and check the system is not being pressuired *air/water will come out of the rad cap usually

   top the coolant up put the heaters on full blow and have it as hot as it will go if the top and bottom hose's on the rad are getting hot and the heaters are blowing worm you dont have a air lock or blockage in the system ....... next step head gasket ~!!!

    I'm surprised no one has mentioned thermostat as that could be locking up.

    ill try another stat and see if its fixed my problem. It isnt half as bad as it was but still rising when giving it some beanz.
    
    I really dont think it is the head gasket thats away as I've been having this problem for a while and havnt exactly been careful, still rip the beanz out it and there no cream and my coolant isnt dropping =S I've had a gasket go before on a rover a it just drank so much water it was unreal.

    is the top hose getting hot? Is it a good coolant mix youre using?
    
    Let it idle and see at what point on the gauge the fan kicks in, just in case the gauge is shagged and showing a dodgy reading.

    I was just going to post, how come no one has mentioned the thermostat! Id check thermostat, see if the fans kicking in then bleed the system if needs be.
