I need the Fiat Punto 60s workshop manual

I need the Fiat Punto 60s 1995 workshop manual, I have to change the heating radiator and for that I need to disassemble the complete board, the problem is that inside there are connections that I do not want to harm, I had to make a bypass at the entrance and exit of the radiator to isolate and not wet inside the cabin.

I hope someone can help me ...
