Can you help me ID this thermostat housing? It came with a group of Ford Kent/Lotus Twin Cam parts. On the side is cast "bleed off valve". I think I've seen these on the '78-'80 Mk1 Fiestas.
I can answer my own question. It's the water neck for a Mk1 Fiesta fitted with air conditioning. Taller neck needed to pass over the high mounted alternator.
