Solved overheating gauge reads different!

[smokin95psd]

Ok i fixed the over heating problem with the t stat! Installed a new motorcraft t stat no more over heating. i noticed my gauge now reads a letter and a half hotter than it used to. my auto meter gauge reads the same 200* degrees. everybody i talked to said the temp sending unit for the factory gauge may be messed up. the truck had never been to 240* until the t stat messed up. nwo remember the truck never got to hot it was still in the normal range but it was hotter than normal. i put a new motorcraft sending unit in but it still does it. about a letter to a letter and a half hotter than before my troubles. help thanks alot

has the air temp been hotter than before though?? on a very hot day its not a problem if the gauge reads a little hotter, its to be expected....

also, if it wasnt a factory Tstat you took out, it may have had a different opening temp too....if its still within normal and isnt fluctuating, i wouldnt be too concerned......

U might want to take the cap off and run it with the heater on full boar for about fifteen minutes though to see if maybe a little air is in the heater core......
