nope havent replaced anything but the thermostat so far,
wanted to get some opinions before i started to invest money into it

as for the sensor i was thinking of that also,only thing that boggles me is that the temp still stays at the A with the fan hotwired to run continuous,which is suggesting to me something other than that or maby a combonation of problems.

i have noticed my upper radiator line not being hard when i squeeze it until temp guage is all the way up before the red.
i put in a factory 192 thermostat.
