What is the "normal" operating temp for an 1988 vette? I am running about 226 to 246 on the highway with the air on. At night, about 205 max. I know it will run a little hotter during the day but that just seems high. I just had to replace the radiator,thermostat and water pump so may by Im just paranoid. I have checked the radiator housing and the cap. Everything has been cleaned out. Any advice?
