Cooling System - Description and Operation 4.0L and 4.4L petrol engines 5 pages807 viewsThis is a 5 page pdf that provides some insight into how the coolant flows thru all the hoses. Of interest is the paragraph,(page 3/5), that attempts to explain how and why the thermostat is designed to open at different engine operating temperatures - in brief, the reason for the spaghetti tangle of small hoses on the top of the engine.

There is also reference to an engine oil cooler that I gather cools something I think related to a supercharger, if fitted.
