I would go and talk to Neil at Sutton Motors he will give you the advice that you need.
This is where I would go, if things get serious and you have a cooling issue go and see Keith Maskell just up the road he advised Land Rover on thier radiator design ( I might add that they ignored him to thier folly ) Neil wil tell you where he is if he is still trading ( I left Alice 12 Months ago )
