I was struggling with figuring this out and I couldn't readily find this (maybe I'm retarded?). So once I figured it out I made a diagram. Just thought I would share it for those of you that are interested.
I did figure out that the coolant flow is the same as an american V8. Which is the type of picture shown in the install diagram with the block heater I was installing on my car. I don't know how all cars are set up, so that is why I'm using the american V8 as an example because I know it is different. Like Charlie once said the system is set up to flow with the direction of convection, and the water pump always sucks from a low point, the lower radiator hose. The only difference with this set up compared to the american V8 is that the thermostat is before the water pump keeping cold coolant from entering before the engine is warm. The V8 set up has the thermostat on the outlet keeping warm coolant from leaving until the engine is fully warmed up. Once it is draw out in a simple diagram it seems very straight forward, compared to staring at the engine compartment.
If I have something wrong please feel free to comment or correct.
