I suspect I may have a sticky thermostat on a C1. Top radiator hose hot but bottom one cold.

I am used to old cars where the thermostat housing is nice and obvious and accessible - but I'm damned if I can see where it is on the C1!

I can see a small domed & finned plastic moulding lying horizontally where the bottom rad hose enters the engine block, so I assume that's it(?) but it looks nothing like any images I've seen on Google of 'C1 thermostat housing'!

So, is that it?

A thousand thanks, in advance!
