thermostat A/C

Since it was  a mild day here ( 0C) I decided to see what else I could find out about the heater system as all the pipes seem to be in place. Logical point to start, I thought, was thermostat. After studying what I was looking at when I opened the back engine cover I decided the thermostat had to be the bit on the right with a threaded bit coming up through the small black panel and a nut on it. Never one to be slow stripping things down I started straight on the nut.  That came off so I assumed the circular bit of the top of the panel was only being held on by the washer Some of you might be ahead of me at this stage and know what comming. Screwdriver under the washer and off it came. Progress, except the thermostat threaded bit was not there any more. Minor things like that don't put me off so next was to decide the top metal plate had to come off. Thats  easy just two tiny nuts. I found the thermostat again but cant find how to either disconnect it from inside or how to get it up high enough to get the nut back on the first bit of thread.  That the point when my brain said it was time to come inside and have a cup of tea. Does the centre piece of that heater shroud come off if i disconnect a nut top centre
as I was thinking of changing the thermostat to see if the problem is there.

whip the whole thermostat housing off and take it indoors and have a cup of tea is the easiest and warmest solution . [-/

Hi Bis,
I agree with the cup of tea idea. Does the centre piece of the whole black housing come off if I remove the top centre nut or do I need to remove all the housing Going out to have another look at it before it gets cold again. Quite tropical to day its back up to +2C

you can get in to the thermostat via the top but its far easier to take off the whole housing as its easier to refit the arm that controls the flap.to undo just go round the outside and loosen off/ remove the neccesary bolts nuts etc.

Hi again,
That cup of tea worked wonders. Had it before I went out. Or perhaps it was the fact I put my glasses on. Found the flap that the thermostat is connected to so I held it up and then was able to get back on the small black centre piece and the nut. All it needs is three hands. I assume the fact that now I have found the flap and also found out I can move it by hand with the thermostat connected and bolted in place it might mean the thermostat is past its sell by date. Going to order a new one anyway and then take the whole housing off.  Might order a couple of spares since it saves money on postage and will have them in the future.
