I am going to change the cooling on my engine from 2wd to 4wd,
Can someone please clarify the standard water connections, I have been unable to get a detailed diagram that shows all the connections, ie what does the small connection on the water pump connect to?

Would prefer a diagram if anyone has one showing all connections inc heater, modine, turbo cooling, expansion tank connections and 4wd thermostat connections.

Thanks in advance
