The last time I was at Beaver Run I noticed that sometimes after starting the car up after the last session I would see the temp needle sky high and then it would come back down to normal once i started moving, like 10 mph or a certain amount of distance, so I don't think it is actually a cooling problem. I wouldn't see the needle do this right when I started it, but I would always catch it back on its way down a couple of minutes later. And on a side note, there is a cool down lap and I would idle my car for a minute or so after parking and the hood was up all day when parked.
That was the first time I noticed it happening. It has happened occasionally since then, and the coolant has always been topped off. And it always happens after a "hot" start. Anyone else experience this funky needle fluctuation? I also saw the needle jump for the first time while sitting in traffic. It went back down to below half again once I got over 40 mph. Don't know if the two are related, but my needle moves now... whereas it never deflected more than a half degree before when fully warmed up.
