ok nope i have no shrouds she runs fine hasnt over heated just runs hot, i asked the radiator specialists about the shrouds and told him what it was in and everything and hes said the new core is a more efficiant one so it will cool better and how big the fan was etc etc, we made a template of the shrouds and it was only just covering the corners of the rad so it made no diffrance at all ,beside its some what cooler over here. like you say Bruce think it's the nature of the beasts, when i last drove it i had one door off and it ran cooler but with people in the back its hard to have a door off besides the amount of air that fan shifts its not wise to have a door off.but at the end of the day if your in my carrier prepair to cook hahahaha ( richard )
