When I bought my truck the temp gauge did not work so I replaced it. Drove it for awhile and the gauge read on the "L" of Normal it started having the symptoms of a head gasket. (White Exhaust sweet smelling). I changed the head gasket. I also replaced the upper and lower Radiator hoses and the thermostat from the Ford dealer. Now it goes past the L but not into the red H zone. When I was driving today the Engine light came on so I pulled off the road and let it cool down. I haven't driven it anymore except home. I noticed that the top Radiator hose to was blazing Hot but the lower one was just Warm and When I turned the truck off I can hear a dripping noise in the engine bay somewhere (It wasn't dripping on-the ground. What is my problem? Any help would be much appreciated.

 

don't you have another thread about having gas in your oil? id say that could have an affect

 

water pump?

 

I replaced the temp sender the temp sensor and the fuel regulator and the problem seems to be fixed
