Get rid of the RR mate before the engine blows, the 4.6 is renowned for coolant problems, I sold one recently and the buyer got 15 miles down the road when it seized, he said that the temp gauge hadn't been climbing to red (which I don't believe) so instead of simply blowing the head gasket he kept motoring and cooked the full unit which cost me over £3k to replace
