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
