Car on the road!!!!

I think that because that is a high spot in the cooling system that any air in the system will stay in that area until it all gets purged out. I know it might be a little work but having a temp guage that has numbers on it instead of the stock guage will give you a better read on temps. The stock one is so vague. Just make sure your shroud is on and the fan clutch is working and that you have a good radiator cap on so it can purge the system of air.

I am sure there are more opinions from some of the more experienced owners though, but that is some of my thinking on the sound. It could also be a noise that the idle control valve makes when the engine shuts off. It makes a similar noise but it is on the intake up high. Keep us informed.
