356 flapper boxes.

[mycar]

As my heating is so rubbish in the 356 I thought I'd investigate.

When the flaps in the flapper boxes are in the closed position, i.e.blocking the passage of air through the flapper box... Is that heating on or heating off ?

Ok, I think I've got it :- flaps open, heating off, flaps closed, heating on !

The beauty of having the lovely lift is it's easy to see what's going on and what's been done. The rods weren't connected up correctly to the heater cans and flapper box levers last time the engine was fitted. All sorted now I think.

The heater cans are clever, little silencers with a valve/trapdoor to allow the heat through.



Looks a bit ropey but actually pretty good considering what it does and where it lives.
