Ah ha, I see. Sounds like the culprit. There is no over heating either. My
neighbour said it could be the waterpump/head gasket. Bar the loss of
coolant no other symptoms of those are present like white smoke and over
heating so hopefuly that's not it. I will start with the t'stat housing.
Usually I only top the tank up by an inch a month usually but today it was
just a smidge under minimum, glad I checked!
I'll monitor the coolant tank daily to see how it goes for a week ? and then
approach the stat housing just to see if there is any further loss. I'm just
wodneirng as I've been using the heating a lot in those 3/4 weeks if that
affects coolant levels ? and now not at all.
.....goes to have a look at the stat bolts ... ok heres a photo might be
better than my ramblings
As always thanks for the guidance MrCheerful
