that sounds about right. Did the cooling fan recall go all the way to 2016?
car has been at dealer for other recall(seat belt) and they didn't t say anything so I would assume it didn't go to 2016.
But I still can t understand the temps I saw a week ago.

Well, the recall was for a worn and/or noisy fan motor, and the following is dated 2015, so may not apply:
But being worn, it may not spin up to speed, or fail to start when needed. That could cause a temp spike. While the notice above doesn't apply to the '16, it can't hurt to check, since the car is already at the dealer.

Air in the cooling system will do that. We swapped in a 5L LS1 into our 3rd Gen Firebird autocross car, and although I thought I got all the air out, the first handful of events I'd see the temp gauge momentarily-spike to 230+ Deg-F. The spike would usually last for about 10-20 seconds then drop back down to a normal range (~180-200).
The first couple of times I almost wet myself and immediately shut the car off. After seeing it a few times, and after I had already verified we had zero leaks, I'd just watch the spike. Sure enough, it would spike, then after a few seconds of running, drop back down. After about 5 or 6 events, that issue is history.

I did think of that but wasn't t sure if it was possible with no leaks and nothing done to the system (probably ever).I do check the level often and never had to add any. Thanks
Just to report back, what I had found was that replacing the radiator cap has solved the issues. I would notice upon cool down that the lower hose would collapse from suction I assume. After the new cap this no longer happens and the temps don't spike as high.
