Tried searching, couldn't find anything. I drove home from Fort Worth last night, about a 20 minute drive. Everything appears normal until I pull into garage. I hear a clicking noise coming from under hood I narrow it down to somewhere around radiator. I looked for loose parts, but see nothing. All gauges reading normal it sounds like it's coming from waterpump area. could this be telling me something? Could this be waterpump problem, or something else? Thanks for any insight. 1990 4.0 all maintenance up to date. And no problems other than the noise.:flipoff:
