yeh sounds like your coupling has gone but also check between rads to be shure
burgerman:
Put a new rad in it, not a flushed one or second hand, A shiney"new" one, Ill bet ya a doughnut it will cure the problem ;)
sardonicus:
Yep,I had the same problem last winter.Long uphill,rad blew steam and water everywhere.I thougt it could be the head gasket !
The p gasket was leaking and I think the previous owner had put a rad turd in it to seal it. Anyway, spotted split in it as well,so I replaced it and has been fine ever since. New rads dont cost much more than £100 I think.

Sorry to ask but how do u tell the differance between the two more blades I think mine is dead anyways cos I can turn it freely when the engine is hot and it wobbles all over the place ?? :oops: ?

No need to be sorry, the serpentine V8 fitted to the soft-dash and 300 series Disco had the fan running the other way, the hub is RH thread rather than LH thread and has a different (smaller I think) nut to distinguish the fact. Anyway, the outside of the viscous hub is the same so it is possible to bolt the fan moulding from one onto the other.
The blades face the other way but it isn't obvious with the fan shroud in place.

I too have been having overheating issues with my Discovery in the last couple of years since it done the head on the way back from a caravan holiday in Cornwall.
I had the head replaced after it was skimmed by a friend and still failed. I now have a genuine water pump and thermostat fitted earlier this year. But when I tow the van it starts to overheat after about an hour and a half of towing! i found that if I put the heating on full with the fan on and reduced my speed below 50mph the gauge would start to drop back to its normal position. So after reading this thread, im wondering if a new radiator would cure my issues?
Also, I have noticed that my Discovery black smokes more since the head was replaced. Could this be be related or am I just getting paranoid!!
Any additional info would be greatly received.
Many thanks,
Sogster.
