they don't have valves anymore, water always flows through the matrix, flaps direct the air through the matrix or pull in cold air
Ok I have even had impellers snap of a Renault pump that had frozen. BUT we turned the crank with a guy feeling the vanes were all in place.
I will admit my first thoughts were water pump as I have had similar before......but my lads mate needs it back for Monday to go to work....Yeah I know not good but the guy is skint. So paying 50 quid on a gamble was not a good option.....he had convinced him self it was a cheap thermostat.
I know some have pins fitted that sheer but the impellor still has a grip on the shafts..

Been ages but I once worked on a Montego, memory is struggling a bit but am sure it was the same sort of problem...well 70% sure 
Turned out the thermostat housing apart from the main pipe connection also had a small bore outlet and it was blocked solid with crud, cleaned it out and problem sorted.
Probably nothing like yours and not the problem but was worth mentioning just in case.

Ok now for the additional we were not given at first. ( or we would not have took the job on)
When it was first purchased second hand head gasket went after 2 weeks.... doh. Now they tell us. Our guess is the new head gasket did not fix it as the heater never worked so they bashed the center out of the thermostat.
So.......I was convinced it was water pump but.....as the guy can't leave the car I am not rushing doing a favour. It was rad pack and bumper removal as one of the thermostat housing Bolts had a duff head. Arrggg.

usually when its head gasket gone the cooling system will pressurise very quickly when cold yet the hoses will be cold or just starting to warm up

coolant cap off and sniff for combustion fumes
Because he reckoned he could feel each of the vanes through the thermostat opening.....does not mean it's still connected 100% though I agree.
ITried it not convinced.....either way.
Does not seem to pressurise at a without thermostat in.
