Duetto (1600) Cooling water lines routing

All,

I need to refurbish my Heater box and all associated hoses in my 1967 Duetto. The hoses connected to the heater box are most likely original and the bypass tube from the main supply line to the engine has been rubbing against the intake manifold.

As the hose is now rubbing against the inlet manifold I need to move the t-piece to a better place. I was thinking of putting it further in the line against the scuttle line.

Does anyone have some pictures of how it should be routed and where I should place the t-piece?

Your positioning looks correct. Do you have it secured under the two metal folding tabs and are your motor mounts solid enough to keep the motor rocking under control? It might also be a a section of hose is a bit long, or short, making it rub.

Nice looking engine bay. Very original looking. Get yourself some crossover clamps for your crossover hose.

I don't know if this original, just how I did it. The metal folding tabs aren't the most secure, my hose pops out and rubs on the white paint.

This is the factory set, the tee fitting is more inboard of the fender wall.
Cheers, Jon

Dr G, Jon,

Thanks for the pictures. I see that the t-piece indeed needs to be closer to the wall - That was the solution I was thinking of.

I guess the cw lines were replaced at some point in time. Yesterday I found that the small 90degree was definately NOT replaced since 1967.

Jon, resurrecting this thread...you noted in your photo of the cooling lines for the 1600 Duetto that they were original. Are those the original hose clamps? Do you by any chance know the name/style of clamp? If so, do you know if they are still available.

Thanks

Adam

The clamps are original. Brevetti is stamped on the metal .. 24 mm.
I have seen them for sale on occasion but I'm not sure they are still being made. Try running a "wanted" in the classified section.
