Bongo Fury

Hi, I have a diesel Bongo and need to replace the coolant pipes to the rear heater matrix, is there any reason these could not be made of copper? as I have the capability to bend and flange copper pipe

Thanks

No reason whatsoever , you could also consider lagging them.
You could also make them from rubber/plastic as long as the materials used are suitably rated.

Thanks, on another note, how do you remove the plastic clips that hold these pipes?

Thanks

did you figure this out I see the nut and bolt just could not undo the clip or see how to undo it

I've just posted a picture of the clip and its release catch on your original post.
