Hi everyone .
Just had the same problem with my rover 75 . Your problem is the CYLINDER HEAD . Exhaust gas as is getting into the water coolant and after 5 or so miles the gas will cause an airlock and the water will not move around the system , top hose will be very hot and under pressure . Radiator will be cold due to fan always on , bottom hose cold . Changing the head gasket will not fix this, you will need a new or recon cylinder head . Hope this help .
