Where does coolant flow in the ZJ 4.0?
 

When I was doing some work on the cooling system a while back, it was pretty clear how coolant was directed across the cylinders. I couldn't see any passages for flow to any other areas though. No luck in the service manual or searching online.

Anyone able to help give me an idea? I'm sure I'll have the engine more apart some time in the next few years, but just curious in the meantime.
