I recently had a problem with my cooling system, the mechanic checked it over and found that the coolant temp. switch was faulty and replaced it, the only problem now is that the dash still says " HOT COOLANT TEMPERATURE" even though it does not go above 202F. Now he is unsure of where to go from there, any ideas?? I was just hoping to get this thing fixed, any help would be appreciated.

Thanks
Steve

Try pulling battery power and see if that clears it. The clear the "U" codes that you will set by pulling the battery power.
