ok peeps after several pm here you go
ok bleed niples are located here
first of all drain coolant complete you will need to disconnect the bottom hose on the bottom of the rad here

and reconnect it
then you will need a bleed bottle i heard of a coke bottle being used ect but get 1 from citroen it will be easyer there less than £20 makes life easyer
ok you need 3l bottles of coolant pore in just over 2L of coolant
undo all 3 nipples(in order of pictures) (this is a vts but all saxos are located in the same place
and now top up with water wait till the nipples start to leak with a nice stream of blue liquid and do them up nice and tight
now start up engine allow to idle for 1-2 mins then raise the revs to 1000-1500 rpm
wait for the cooling fan to kick in then return rpm to idle and allow the fan to kick in once again remove bleed bottle and give the car a good run
return and check the level all ok sorted
remember if this helps set me up a rep guys and girls cheer steve
ps ill try and get a pic of a bleed bottle
