I took the car out for the inaugural ride today, of course it overheated. I looked at the fluid level and it was quite low, luckily I had extra in the trunk. After I added fluid and let it cool down it ran pretty well and the cooling system seemed to be working well. It lingered between 190 and 210 until I got to where I was going and had to sit at idle for awhile and it krept up to 230 or so. So I parked it and waits for it to cool down a little, it wouldn't start until it cooled down to 200 again. Any tips to get my cooling system working better at idle?
