Boxer 1.9 Diesel Workshop Manual.

Hello friends, they could help me, buy a 1.9 boxer in poor condition that I am repairing, I came halfway, I have already assembled it the whole engine but as it was incomplete I do not know which one how the refrigerant circuit is going. I have many hoses or I have connections if they could help me with a workshop manual to know where each of these will be very grateful.
Greetings.
