I have a 2011 Ford SD 6.7 Power stroke and the engine fan runs almost constantly. I saw another post on this forum that these trucks are prone to cooling problems. (I have smelled coolant but only slightly) The post said that the radiators have a leaking problem.Has anyone else experienced the engine fan issue? If so how did you address the problem? I don't have extra cash to have someone just throw parts at it until they figure it out.    Thanks in advance jeepguy66
