Chevrolet C10 Manual

Estimated, by chance someone will have the manual of the Chevrolet C10 1979 onwards, to this vehicle of my belonging an engine change (the same as the original) was made but the old man who changed it does not connect any hoses and suppressed some, and I need to know where they go so that the engine works like people and all this I add that something left badly that when checking the level of oil, white salt Refrigerant liquid to the engine and at the moment the truck is lying.
