   whoops
   
   managed to snap one of the bolts that connects the pipe from the rad to the thermostat housing, so half of its stuck inside. had a drill to it, nothing. car will drive but forms airlocks every other day
   
   how hard is it to remove the housing and replace it? or is there a better way of getting the broken bolt out?

   housing just bolts on so easy to remove.
   
   Just drill the bolt out and then run a tap through it to clean it out

   well you could buy a tap set, for less than a mechanic would charge to do it I'd say + you'll have the set in the future when you need it.

   If you take the thermostat housing off you may find you have a bit of bolt to hold and screw out.
   If its snapped below the surface then use a quality easx out

    I don't use these 'easi-outs' at all - don't trust them.
    
    Thought I'd bought a quality set, and it snapped on me and was an utter ballache trying to drill it out along with the originally snapped bolt.
    
    Rather just drill bolts out on their own.

    This will cost you less than a mechanic and will be handy to have anyways
    
    This one is cheaper tho

    Is the bolt loose inside? if it is get a flat head and tap a way untill its loose then keep trying to turn it anti clockwise untill it comes out.
    
    If not best bet is to drill it out, ive used easy outs before and they really can snap so easy and are made from colbolt. If you do use an easy out go very very slow.

    "eazy-outs" should be sued under the trade descriptions act
