140

120 is not too hot if it stays there but if it jumps to 140-145 thats a problem

1,855

These cars generally do NOT run hot; have your mechanic flush the system and put in the proper mixture first and replace the thermostat while at it. See if that solves the problem...if not move on to the temperature sending unit.....
