Hi Everyone,
Can anyone help me with a photo of the three way pipe that sits in the engine bay, near the bulk head and supplies water to the heater and also to the inlet manifold?
I've searched online for this part but as I don't know what it's called in the Fiat parts list I've not found anything.
I removed mine years ago because it was broken and I didn't bother with the heater but I'd like to reconnect it now and that three way pipe has long since disappeared.
Thanks so much for any help.

Our South African Uno Mias seem to all be the same. I'm impressed with how your doors look. Mine rotted out at the bottom and I had to do some bodywork to fix it.

I've had my heater core out for cleaning, so I've had to bypass this manifold on mine, but here's a photo of it. The pipe from the inlet manifold goes to the bottom, then the return to the front of the engine goes out the left. There's a small orifice as a restriction in the plastic manifold to discourage much flow during normal operation with the heater valve in the cabin turned off.

Thank you so much!

That's exactly the piece I'm looking for.

As mine was removed a long time ago I'm going to make a replacement out of copper pipe.
