hi Stuart

First i would check your rad fans do come on 1. Turn on the mode 
switch to AC function do your fans come on straight away they should 
on a standard set up D    2. Jumper the two wires to the rad fan 
switch in the LH engine bay coolant pipe again the fans should come 
on staight away...

Have you felt the steel pipes that go to the radiator whilst the 
engine is warming up ? after the pump thermostat has opened then 
this allows hot coolant to the rad, if these pipes are still cold 
when the guage is at normal running temperature then this thermostat 
is stuck shut and not allowing coolant flow to the rad or back 
again .

Or you could still have a air lock... do you have a pump thermostat 
housing air bleeder, to the return pipe hose fitted?  ( i would get 
one DMUK have them for a reasonable price. ) 

Is the radiator blead of all air??...from cold *carefully* remove 
the little top hose from the rad till coolant flows out ( the rad 
nipple is plastic )... from cold i tend run the engine and whilst it 
is running i remove this a couple of times to release any trapped 
air in there... i also leave off the header bottle cap for a little 
while to disperse any air (only whilst the engine is still cold to 
warming up thou.:) )

My advise on filling is to make sure the car is on a horizontal 
level or even back end higher and *slowly* fill it using a funnel 
and jug not a hose pipe or by "glugging" it in  when you feel there 
is enough in the system to fill the radiator then bleed this 
first... then go on to fill the rest of it back to the bottle max 
fill line... make sure your hot/cold switch is set to #hot# so the 
internal heater matrix gets purged and filled... dont see that 
written down and it is easily overlooked...! I see yours doesnt blow 
hot ... could be trapped air in here

Hope this helps... just keep an eye on your guage ...dont overheat 
whilst you are diagnosing your problem ! :)

If you want to chat about this please call me 07779 081368, yes its 
damm frustrating but can only be one of a few things..

Also sorry but i have to say that im assuming you have a 
new 'proper' DMC pump ???
