Hello All, new to the team and new to the vette family...I have a 78' silver anniversary ed. I replaced the temp sending unit and the temp gauge...when running the gauge is spot on 200 degrees, but when cold, it shows 100 degrees, isn't this high for a cold temp? I am in Florida and I was expecting the gauge to go below 100, a side note: the minimum in the gauge is 100. Thanks for your help!
