Well I changed the viscous fan and it's had a slight improvement, but
it's still too hot for my liking.

So it looks like we're down to thermostat or radiator.  I've got a new
thermostat (I've found that the LandRover Orphanage is now on the same
site as where my son works :-) but who else would you reccomend to get
a new radiator from ?

I know I could flush this one through, but I have been told a common
problem is furring up in the centre which you can't do much about.

Cheers

Peter
