    Range Rover 4.0 P38 water pressurizing HELP!!!

    Hi I went through a similar process and it cost hundreds but it was the dreaded head gasket after all, even though the gas test kept proving negative! The main cause of the initial over heating was the viscous fan unit which looked fine and seemed to be turning ok but was gone with no real...
